As cotas XFS não são uma opção remountable. Hardwareseitig gibt es bei Btrfs jedoch Ausnahmen. 여러 가지의 HDD를 장착하여 사용을 하신다면 사진이나 중요한 자료들을 저장하는 드라이브에는. 7. However, I was using the openSUSE's default partition layout, which is btrfs for / and xfs for /home. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. btrfs is also slower in some benchmarks but I very much doubt thats visible in normal use. With not having the time to conduct the usual kernel version vs. You might also want to consider Btrfs for your array drives, but you should be aware of the potential risks. Ext4 is kind of the "tried and true" old file system that works and has good performance, but lacks many modern features, like snapshots, subvolumes, etc. It is the default file system in RHEL 6, Debian 7, Ubuntu 18 and so on. EXT4 vs. BTRFS hatte auch etwas höhere Latenz als EXT4, was bedeutet, dass es länger dauerte, bis Dateien auf dem Dateisystem zugegriffen werden konnten. Now, lot of development efforts are pushed to Btrfs development and most probably it will become next generation default FS for Linux, a successor of EXT4. 0, and is just some quality-of-life command line. 另外，我们常说的file对象，它用于关联进程和dentry对象的. XFS and ext4 are probably where I'd look for a single disk hard drive. The only concern I have is performance, maybe btrfs in a HDD will be really slow. 6. while ext4/xfs/btrfs are rather classical filesystems as such (and might have their benefits or not) - ZFS is not. Btrfs also has snapshots so you can revert back to an earlier snapshot easily, say you run arch and some update borks your system (highly unlikely), you can simply revert back to the last good snapshot. A daily snapshot of Ubuntu 19. Vide. XFS vs EXT4!This is a very common question when it comes to Linux filesystems and if you’re looking for the difference between XFS and EXT4, here is a quick summary:. XFS. With not having the time to conduct the usual kernel version vs. Softwareseitig werden die Dateisysteme ext4 und Btrfs generell ab Diskstation Manager (DSM) 6. File-systems tested on the NVMe SSD included Btrfs, EXT4, F2FS, XFS, and NTFS. XFS is about as mainline as a non-ext filesystem gets under Linux. 특히 시놀로지에서는 데이터 보호와 백업의 용이함을 장점으로 내세운 Btrfs를 권장합니다. Where “file-sparse” is the file name, and the number at the end is the size that can be set in bytes, megabytes, and so on. Compared to Ext4, XFS has a relatively poor performance for single threaded, metadata-intensive workloads. What concerns me is reports that its heavier on ssd's due to all the extra metadata tracking etc. Improve this answer. EXT4 vs. For SSDs, F2FS really is a hands down winner still, although EXT4 and XFS are catching up, they still lose. I heard BRTFS filesystem with continuous trim and unit allocation size of 64kb are the best configs so far. 7 star rating. Installing and booting with BTRFS has its advantages too. Você pode então configurar a aplicação de cotas usando uma opção de montagem. But as some users found out, automatic snapshot (at the time it was first released) ate disk space on single user installations. Checksum: if your file (or some metadata) gets corrupted, the checksum will detect and in some case. Btrfs es mucho más rápido de lo que crees basándote en esos benchmarks, ya que no se ajustan a tu caso de uso. 4 EXT4 / XFS / Btrfs RAID Performance On Four HDDs Storage : 2019-12-28: Benchmarking The Experimental Bcachefs File-System Against Btrfs, EXT4, F2FS, XFS & ZFS Storage : 2019-06-25: Optane SSD RAID Performance With ZFS On Linux, EXT4, XFS, Btrfs, F2FS Storage : 2019-06-20: Linux 5. The way you describe this workload, I think it is not very demanding. How do the major file systems supported by Linux differ from each other?I've heard good things about BTRFS, and I'd use XFS but I dislike that it takes an significant % of the free-space off the bat. Offizieller Beitrag. - No RAID. I'd say ext, because it is faster, and because you asking means, that you don't know how to use btrfs features, otherwise the choice is obvious: need snapshots -> btrfs, need reflinks -> XFS, default -> ext4. I had no bad experience myself with btrfs so far, but still have not tried it with anything more complex than raid1 over a long time and while I assume many horror stories out there are just deprecated as btrfs keeps improving, it can do a lot more than ext4. Both ext4 and XFS should be able to handle it. Yeah reflink support only became a thing as of v10 prior to that there was no linux repo support. Ext4 te permite crear un máximo de 232 archivos. Notes[ edit] ^ IBM introduced JFS with the initial release of AIX OS/2 Warp. At the time, ZFS was significantly slower than xfs and ext4 except when the L2ARC was used. 500GB HDD formatted as NTFS for luks containers. Ext4 tiene el registro en diario de forma predeterminada y es probable que los nuevos usuarios no sepan cómo deshabilitarlo para guardar lecturas / escrituras en sus. So now I can boot up into a snapshot. Mar 14, 2012. The ZFS file system combines a volume manager and file. . - Bảo vệ dữ liệu. The maximum partition size of a btrfs file system is 16 exbibytes, and the maximum file size is also 16 exbibytes. While RAID 5 and 6 can be compared to RAID Z. 0 SSD testing ran into a strange performance drop while Btrfs. 5. With not having the time to conduct the usual. Hello guy's "EXT4 vs BTRFS" -that's the question *Let me guess what will happen, you guys will jump in and comment technical replies* But that's not the case here Imagine: There is someone that he/she does not have that much knowledge about Linux. But they come with the smallest set of features compared to newer filesystems. Note that while these tests are not indicative of real-world performance, we can extrapolate these results and use this as one reason. BTRFS improves file addressing capacity to 16 EiB and volume sizes up to 16 EiB, just like ZFS. 1. Advantages of Btrfs over Ext4. The arguments about ext4 vs NTFS have been raging online for decades now. For example it's xfsdump/xfsrestore for xfs, dump/restore for ext2/3/4. But. I was using NTFS due to compatibility. The space savings with zstd compression are insane, and I see virtually no performance degradation. you don't have to think about what you're doing because it's what. but rather comparable to the usage of md-raid underneath or LVM. , power failure) could be acceptable. Not a ton of bells and whistles, but they Just Work. Running this fio command, I get about 2. BTRFS have some fancy features, and could help. BTRFS's problems are exaggerated, and depending on your use case may fit better than ZFS. The total throughput is better than with ZFS (40k vs 60k), but the jitter is more severe. XFS is more and more mature than Btrfs, but. To reserve an external journal with a specified size when you create an XFS file system, specify the -l logdev=device,size=size option to the mkfs. 5. 我们主要讨论Linux中主流的三个文件系统：Ext4、XFS以及Btrfs的功能特点 ext4 文件系统由 ext3 文件系统改进而来，而后者又是从 ext2 文件系统改进而来。 虽然 ext4 文件系统已经非常稳定，是过去几年中绝大部分发行版的默认选择，但它是基于陈旧的代码开发而来。I've compiled in tmpfs for over a decade now. - chống phân mảnh dữ liệu nhanh chóng. However benchmarks test quite narrow parameters which may not be reflected by running an OS. Out of curiosity I have tried BTRFS (still unstable so I can't really expect to be able to use it) and noticed that the read speed is about 150% of ext4 - while write speed. To be clear, I am using RAID0 with two SSDs with strip size of 256Kb. In some areas Btrfs was showing great improvements in performance, especially for the RAID setup, but it still lacked in some other areas. ZFS can also send and receive file system snapshots, a process which allows users to optimize their disk space. It's fine otherwise, but if you ever think you might want to shrink your partition, use ext4 or btrfs instead. I've seen benchmarks (eg: this one) that put btrfs considerably slower than ext4. We currently recommend XFS for production deployments. Data Colossi & Data Centers: Ext4 is non-negotiable for handling extensive data transactions. XFS, EXT4, and BTRFS are file systems commonly used in Linux-based operating systems. This is the most desired feature of Btrfs. 8ではPhoronixのテストの結果ではXFSが非常に速く、Ext4が遅い。Una vez que hemos conocido las principales características de EXT4, vamos a hablar sobre Btrfs, el que se conoce como sucesor natural del sistema de archivos EXT4. Unix, etc. Ext3 and ext4 have some very specific differences, which I'll focus on here. - Tạo và lưu trữ snapshot. ZFS also has more options for caches and such things than EXT4. my oldest one a OCZ Agility3 60GB is. Hi, I think BTRFS is actually faster then ZFS on Linux. About Linux filesystem, I prefer Ext4 > XFS > Btrfs, it seems that Btrfs is slow for IO, and XFS. btrfs 可以支援 snapshot, 但 ext4 不行, 如果一開始就採用 ext4, 日後如果要使用 snapshot 功能, 必須將 NAS 的資料備份出來, 重新 format 成 btrfs 格式. X percent… The more modern filesystems of BTRFS and ZFS not only have data integrity features but also the inline compression pushes the efficiency past 100%. 3. mount the recently formatted btrfs partition without special options just with mount /dev/nvme0n1p2 /mnt and create the subvolumes you want, e. (2013) compared the performance of Btrfs against XFS and ext4. We believe that btrfs has the correct feature set and roadmap to serve Ceph in the long-term, but XFS and ext4. Probably those edge cases are not visible on an external USB hard drive, could be visible with external SSDs on a USB3. There’s very little difference between EXT4 and XFS, both in total throughput and behavior over time. Because of that, the Ext4 file system is very stable. 0 File-System Benchmarks: Btrfs vs. The ext FilesystemsHere is a look at the Linux 5. ”. If you think that you need. Various benchmarks have concluded that the actual ext4 file system can perform a variety of read-write operations faster than an NTFS partition. This feature allows for increased capacity and reliability. btrfs turns off metadata duplication on a single device when /sys/block/ device /queue/rotational is zero for the single specified device. The answer is zfs. The 3 types of file systems support large file size and volume size. 하지만 리소스 문제나 호환성 등을 생각한다면 EXT4도 포기할 수 없죠. F2FS vs. When use btrfs it's 35-40 MB/s. g. Just EXT4, yes. Btrfs使用校验和来确保数据不会被破坏，另一方面，Ext4不能确保数据的完整性。 Btrfs提供了文件系统中存在的压缩算法，允许在将数据写入系统时在文件系统级进行压缩. The XFS filesystem is the default filesystem in RHEL, CentOS, and other RHEL-distros such as Oracle Linux, Rocky Linux, and AlmaLinux. Otherwise btrfs for snapshots via snapper. 6. With the comparison table out of the way, let’s get right into it! Ext4 Overview. A Seagate FireCuda 520 PCIe 4. While looking at the filesystem options it seems like BTRFS is a lot more stable than it was the last time I had to install arch so now I am seriously considering using it. Data integrity protection. XFS and btrfs are two advanced file systems for Linux that offer significant improvements over ext4. But it's slow when used with fsync -intensive programs such as dpkg (I know eatmydata and the crappy apt-btrfs-snapshot programs) and I won't setup a. So for a large video collection, I think I will stick with ext4 still. 2. As others have said, btrfs is newer and offers a few advanced features for backups (snapshots) and data integrity. Till the moment, the ext4 seems to be a better choice on the desktop system since it is. 0 unterstützt. I remember being on ext4 using Timeshift but it only supports rsync–so slow. @Falzo said: I think in general the comparison is a bit. The fourth generation File System of the Ext (Extended) file system family. With Bcachefs core development being done and the possibility of this file-system being mainlined soon, here are some fresh benchmarks of this file-system compared to Btrfs, EXT4, F2FS, XFS, and ZFS On Linux. 8ではPhoronixのテストの結果ではXFSが非常に速く、Ext4が遅い。 Una vez que hemos conocido las principales características de EXT4, vamos a hablar sobre Btrfs, el que se conoce como sucesor natural del sistema de archivos EXT4. , power failure) could be acceptable. Difference between Ext4 vs Btrfs filesystems on Linux. btrfs/ext4 volume on top of a ZFS zvol. So if you are after the most speed for the buck and if your NAS is already doing RAID 5 or more, you could go for Ext4. I'd like to take advantage of an OS switch to upgrade to BTRFS. Though EXT4 has few strong capabilities, it is reliable and well-maintained across all Linux operating systems. ZFS is open source, it isn't "owned" by Oracle. However, BTRFS had significantly better performance with small files than EXT4. My current setup is /@ for the rootfs, /@home for home dir, works great. Running AIO-Stress on the Western Digital VelociRaptor was yielding speeds not technically possible for the Serial ATA 3. - no encryption. Add a comment. Does that mean that if I'm using btrfs snapshots, it will not save parity data for any snapshots other than the current state of the drive, that it will only save parity data for one snapshot other than the current state of the drive, or that it will fail entirely?Generally, would go with btrfs. 7 - EXT4 vs. A) crater. This is useful, though far less complete than the block-by-block checksums of btrfs and ZFS. 对于一些文件系统如Ext4等，在硬盘格式化时就全部确定了，而对于XFS则是动态生成的，BtrfS则是更特别的动态实现。. ext4 or XFS are otherwise good options if you back up your config. With btrfs I got 130-160MB. misleading. It's not "better" because better depends on your use case. 0 File-System. XFS is Red Hat’s enterprise filesystem (until they finally trust btrfs). But not enough users follow the guide on and instead do stuff that actually makes the system worse. There won't be any noticeable difference. but for the shared servers with many users you might consider xfs for the parallel IO and number of files. Also BRTFS compresses the file system using less space compared to EXT4 but again the tradeoff is it uses more computer. It’s an improved version of the older Ext3 file system that includes a lot of great features, including ones for Solid State Drives (SSDS). The Btrfs filesystem supports read-only and writable snapshots of the file. Learn how to compare btrfs with other file systems like ZFS, ext4, or XFS in terms of features, benefits, and drawbacks. Not only does both file systems feature a more robust data assurances then XFS (the mature fsck for Ext4 and checksums and data. But I would still refrain from using it on the deck due to the case folding trouble. EXT4 is very low-hassle, normal journaled filesystem. If you are looking for advanced features such as data checksumming, snapshots, and data deduplication, then Btrfs may be the better option. ext4 is an "advanced" version of ext3 with various improvements, basically an upgrade to the ext3 format. Seriously, fuck them. doc_willis • 2 yr. 6. (ext4 for general use, xfs for MythTV) On the other hand, I lost an entire filesystem with btrfs - the utilities couldn't identify anything on the (raid-1) drives as btrfs, it wasn't just corrupted, it went missing. Btrfs Benchmarks comparison, here is a wider look at mainline file-systems on the Linux 4. EXT4 has been the Linux default since 2006, following the previous EXT3. I'd say ext, because it is faster, and because you asking means, that you don't know how to use btrfs features, otherwise the choice is obvious: need snapshots -> btrfs, need reflinks -> XFS, default -> ext4. 0. EXT4 is better for small files and day to day use. For example, xfs cannot shrink. X percent… The more modern filesystems of BTRFS and ZFS not only have data integrity features but also the inline compression pushes the efficiency past 100% in many cases. Its not faster or more stable then the other two. NVMe drives formatted to 4096k. Zu diesen gehören eine integrierte RAID-Funktionalität, ein inkludierter Volume Manager und die Unterstützung von Dateisystemen bis 16EiB. - Btrfs hỗ trợ tính năng pool trên ổ cứng. The Ext4 filesystem does not support creating snapshots of the filesystem. Ext4 is built on older technology, so it lacks modern file-system features found in systems like E2FS and BtrFS. ZFS. BTRFS subvolumes and the way a distro like Opensuse handles it, by using subvolumes and snapshotting on upgrades, is really nice. For example btrfs supports transparent file compression. Ext4 provides more flexibility in terms of data storage. 再將資料再回存到 NAS, 這部份會花費很多時間. Btrfs is the recommended file system to use in most scenarios. . The Slant team built an AI & it’s awesome Find the best product instantly. It takes a second to snapshot, and deletes of a snapshotted tree what takes ext4 26 hours is a few minutes on btrfs. I see that it says multiple btrfs snapshots are not supported. wbeater • 3 yr. In the past, I have often seen statements that EXT4 is better for gaming than XFS. But still iffy on high raid levels. Although Btrfs lacks stability and maturity as of this writing, it is more feature-rich than EXT4 despite this. NTFS and FAT are known in Windows environments. 2. Built By the Slant team. Data integrity protection. Red Hat Training. BTRFS has better backup capabilities, but is considered less stable, despite it working for me just fine with my testing of it. NTFS OpenBenchmarking. Regarding filesystems. 6：顺序. The four hard drives used for testing were 6TB Seagate IronWolf NAS (ST6000VN0033. My current setup is /@ for the rootfs, /@home for home dir, works great. For btrfs you have to do most from CLI. 0 hard drive when using EXT4 and XFS. Both Btrfs and ZFS offer built-in RAID support, but their implementations differ. Hello everyone, The time has come again for me to reinstall arch once more. Ext4 is the default system for most Distros. Use whatever your distro vendor supports: on Redhat and spinoffs, use XFS+LVM (the latter gives you snapshotting capabilities today;: XFS itself will receive them in the medium term), on Suse use BTRFS. Add to Chrome Add to Edge Add to Firefox Add to Opera Add to Brave Add to Safari. The XFS File System. If you have multiple disks — and therefore parity or redundancy from which corrupted data can theoretically be recovered — EXT4 has no way of knowing that, even less using it to your. The benchmark I linked attributes this to copy-on-write behaviour of btrfs. . Have snapper to create pre/post BTRFS and LVM snapshots. Features of the XFS and ZFS. 0 SSD drive used was a 250GB Samsung 850 PRO solid-state drive connected both via SATA and then a SATA. 0 File-System Benchmarks: Btrfs vs. ) TL, DR: All 3 major next gen CoW file systems have their advantages and drawbacks, and I figure integrating them into my workflow is the only way to fairly evaluate them see how they work for myself. XFS doesn't have any RAID, while Btrfs RAID is not yet completely stable and is in its early days. Of all the niche file systems, one of the most interesting is Z File. Btrfs vs Ext4. Example 2: ZFS has licensing issues to Distribution-wide support is spotty. As Microsoft makes more progress with ReFS on Windows 11, Linux is also getting performance optimizations and improvements on some of its major file systems, namely, F2FS, Btrfs, and EXT4. 和 ext4 和 XFS 一起使用的工具比较 法律通告 Settings Close. windows and linux use one big D: for data storage, NTFS C: and EXT4 Linux are only for OS and software. 1. The only time there were issues was when my RAM sticks went bad and btrfs detected it and put my FS into read-only mode to prevent corruption. It lived enough, time to move on. I've set up and used btrfs for years and later zfs for the past few years both professionally and on home servers. I currently have a ds1819+, currently, i have 8 x 4tb (5400rpm) 32G of ram 2x2tb nvme cachethe system is super fragmented and super slow synology says that i need to backup everything and recreate the volume. ext4 can claim historical stability, while the consumer advantage of btrfs is snapshots (the ease of. Viewed 6k times. And generally, files that arent compressible, wont be forcefully compressed. Ext4 is probably the final evolution of the ext filesystem (which started with ext, then ext2, ext3, and now ext4). Rep: XFS has unbalanced performance, but in the best use case blows away many other formats. If you use Debian, Ubuntu, or Fedora Workstation, the installer defaults to ext4. 38. Mar 14, 2012. However, to be honest, it’s not the best Linux file system comparing to other Linux file systems. Now today I had a power outage on our office server and I discovered that one file on the JFS volume has been completely corrupted. This process have two main steps: 1. BTRFS vs EXT4 speed and compression. Compared to classic RAID1, modern FS have two other advantages: - RAID1 is whole device. Then later, I was actually able to convert that from btrfs-raid10. at least as much as ext4 (which isn’t all that trusted by SUSE). Both are suitable for everyday use, but it's worth noting that. Ext4中没有这种内置的压缩支持。 Btrfs直接从磁盘删除重复数据，而Ext4不能这样做， Btrfs支持. You can sometimes run into bugs and issues if your home directory is partitioned in XFS, BTRFS, or ZFS. OMV4 or OMV5. In terms of XFS vs Ext4, XFS is superior to Ext4 in the following. Compression is usually not very efficient on game data (that is already compressed) and can increase fragmentation. I did this to all of my partitions, including home. BTRFS系统性能最差，下面是去掉该系统其它3种的对比. We also provide useful. However benchmarks test quite narrow parameters which may not be reflected by running an OS. which btw you should put in here then as well. List of archive formats. ago.

Btrfs supports RAID 0, 1, 10, 5, and 6, while ZFS supports various RAID-Z levels (RAID-Z, RAID-Z2, and RAID-Z3). file-system comparison, here are some fresh benchmarks looking at the Btrfs, EXT4,Sure, BtrFS has its benefits and novel features, but "has never once failed me in 10+ years" is an incredibly strong reliability trend that I'd be hesitant to trade for those, especially in a piece of my infrastructure where a single failure could potentially cause massive loss of data and subsequent time spent recovering from backups/etc. The Ext4 File System. It's not the fastest but not exactly a slouch. As far as I know, the 4k block size is important for such webgui, it makes it faster to open sites (for ex. For a future article will be a look at non-mainlined file-systems, including ZFS On Linux. LVM has snapshots. . XFS was surely a slow-FS on metadata operations, but it has been fixed recently as well. The 12,3 % reduction in compilation time with BtrFS is a nice improvement but pales compared to the 58,4 % reduction seen with Ext4 on the same hardware doing the same task. NTFS. Reliable! I used it in Rsync mode as only my backup disk is btrfs, everything else was ext4 or XFS. Ext4 is the default file system on most Linux distributions for a reason. I’d still choose ZFS. A Seagate FireCuda 520 PCIe 4. 14 SSD Benchmarks With Btrfs vs. It utilizes a b+tree structure instead of the traditional linear layout found in most filesystems today, allowing it to better manage larger datasets more efficiently than other systems like ext4 or Xfs. Btrfs is newer and more experimental, but offers advanced capabilities like snapshots, checksums, and inline compression. Você deve ativar as cotas na montagem inicial. Back when Bcachefs debuted in 2015 I ran some initial. ReiserFS is another filesystem common to linux systems, but with some ongoing codebase issues whereby it periodically tries to kill your wife. Ext3 and Ext4 perform better on limited bandwidth (< 200MB/s) and up to ~1,000 IOPS capability. It was also 164% faster in post-snapshot reads and 17% faster in post-snapshot writes. XFS. Quota journaling: This avoids the need for lengthy quota consistency checks after a crash. In summary, both Btrfs and Ext4 are good options for your NAS, and the choice between the two ultimately depends on your specific needs and use case. Note that everything with LVM is at the block level which has major limitations. XFS is very well established and changing slowly, and the same can be said for EXT4. You will see the difference especially with autosaves in Satisfactory for an example. 7. The XFS one on the other hand take around 11-13 hours!Reviews of EXT4, EXT3, XFS, BTRFS, and ZFS. The fastest for the SATA/USB tests was XFS followed quickly by EXT4 and then F2FS. 3. Some feel that it is not mature enough for production use while there are also early adopters of this. Pro: supported by all distro's, commercial and not, and based on ext3, so it's widely tested, stable and proven. 15 or newer (Please the same OS using same activating services and same apps!)The snapshots do not take up any space. They both use delayed allocation to achieve file fragmentation while both do not support mounted snapshots. A daily snapshot of Ubuntu 19. 15 Comparing KPTI/Retpoline. If fs performance is the only or most important thing for you, then use xfs - it's the clear winner, by far. The two primary reasons I use btrfs are easy to setup and maintain RAID arrays, and. Same could be said of reads, but if you have a TON of memory in the server that's greatly mitigated and work well. In Summary, ZFS, by contrast with EXT4, offers nearly unlimited capacity for data and metadata storage. - Đảm bảo dữ liệu khi thực hiện backup. could go with btrfs even though it's still in beta and not recommended for production yet. The benchmark results of three most common file systems under Linux environment were given in this paper. In a significant data corruption, Ext2 and Ext3 file systems are more possible and easy to recover data due to their data redundancy compared with Ext4. $ sudo su - # fsck. Then again maybe ZFS is the best to use. Here are the major feature of BTFS over ext4. 240GB SSD formatted as EXT4 for main OS. It's got good features. xx kernel days was an entirely different story, however. #11. Each one might work for you based on YOUR needs! Supp. Also, reducing the life of my SSD by a month is worth winning an argument from which I get absolutely no benefit. EXT4 being the “safer” choice of the two, it is by the most commonly used FS in linux based systems, and most applications are developed and tested on EXT4. That being said, it is meant as a temporary solution to migrate data to a native Unix file system, such as ZFS or UFS. BTRFS bietet, mal abgesehen von der Möglichkeit einer Inline Deduplizierung, beinahe alle Features von ZFS. In fact, BTRFS is also a copy-on-write system to support fault tolerance and file recovery, and provides easy management. 1. ext4 is not recommended. These included Flash-Friendly File System (F2FS), B-Tree Filesystem (Btrfs), and fourth extended filesystem (EXT4). Now Fedora just needs to implement it properly like openSUSE. The EXT4 f ile system is 48-bit with a maximum file size of 1 exbibyte, depending on the host operating system. I have 6 disks so I have created 3 logical disks, 2 SSDs each - just for testing. That is according to my quick read of various Phoronix tests. NT-based Windows did not have any support for FAT32 up to. ) XFS.
