So as an example, the 2.6.18 kernel is not able to support native mode 4k sector drives – that means all Red Hat Enterprise Linux 5 distributions, all Oracle Enterprise Linux 5 distros using the RHEL-compatible kernel, SUSE Linux Enterprise Server 10 etc.

LWN.net: 'Recently, there have been a number of reports that Linux is not ready to work with these drives; kernel developer Tejun Heo even posted an extensive, worth-reading summary stating that '4 KiB logical sector support is broken in both the kernel and partitioners.''

As of v2.6.33, Linux ATA drivers do not support drives with 4KiB logical sector size although there is a development branch containing experimental support. For ATA drives connected via bridges to different buses - USB and IEEE 1394, as long as the bridges support 4KiB logical sector size correctly, the SCSI disk driver can handle them.

LIO (Linux-IO) is the standard open-source SCSI target in Linux by Datera, Inc. It went upstream with Linux kernel version 2.6.38. COMSTAR (Common Multiprotocol SCSI Target) is a software framework that enables any Sun OpenSolaris host to serve as a SCSI target that can be accessed over the network. Linux out-of-tree and legacy

The Linux NVMe driver is natively included in the kernel since version 3.3. NVMe devices should show up under /dev/nvme*. Extra userspace NVMe tools can be found in nvme-cli or nvme-cli-git AUR. See Solid State Drives for supported filesystems, maximizing performance, minimizing disk reads/writes, etc. Performance Sector size
