The XFS guaranteed-rate I/O system provides an API that allows applications to reserve bandwidth to the filesystem. XFS dynamically calculates the performance available from the underlying storage devices, and will reserve bandwidth sufficient to meet the requested performance for a specified time. This is a feature unique to the XFS file system.
He intended it to be an advanced file system with modern features [16] like those of ZFS or Btrfs, with the speed and performance of file systems such as ext4 and XFS. [3] As of 2017 Overstreet was receiving financial support for the development of Bcachefs via Patreon. [5] As of mid-2018, the on-disk format had settled. [8]
Most free and open-source graphics device drivers are developed by the Mesa project. The driver is made up of a compiler, a rendering API, and software which manages access to the graphics hardware. Drivers without freely (and legally) -available source code are commonly known as binary drivers.
ext4 (fourth extended filesystem) is a journaling file system for Linux, developed as the successor to ext3.. ext4 was initially a series of backward-compatible extensions to ext3, many of them originally developed by Cluster File Systems for the Lustre file system between 2003 and 2006, meant to extend storage limits and add other performance improvements.

Partial (with third-party drivers) Yes ? No No ? Yes Yes (from OS/2 1.2) ? No ? ? No NTFS: Partial (with third-party drivers) Yes Native since Linux Kernel 5.15 NTFS3. Older kernels may use backported NTFS3 driver or ntfs-3g [72] Read only, write support needs Paragon NTFS or ntfs-3g: Needs 3rd-party drivers like Paragon NTFS for Win98 ...
The speed performance of ext3 is less attractive than competing Linux filesystems, such as ext4, JFS, ReiserFS, and XFS, but ext3 has a significant advantage in that it allows in-place upgrades from ext2 without having to back up and restore data. Benchmarks suggest that ext3 also uses less CPU power than ReiserFS and XFS.
fsck time/Inode Count(ext3 vs. ext4) With ext4 the e2fsck runtime should come down considerably, as can be seen from the graph. As the userspace companion for the ext2, ext3, and ext4 drivers in the Linux kernel, the e2fsprogs are most commonly used with Linux. However, they have been ported to other systems, such as FreeBSD and Darwin.
Although ext is not a specific file system name, it has been succeeded by ext2, ext3, and ext4. It has metadata structure inspired by traditional Unix filesystem principles, and was designed by Rémy Card to overcome certain limitations of the MINIX file system.
