Split SAS/SATA drives with power failure protection into separate sections for SAS and SATA
Flash drives used for top-level vdevs or SLOG devices should have power failure protection to protect both their own metadata and flushed data. Protection of unflushed data does not occur on mechanical drives and therefore is not a requirement of filesystems in general, which include ZFS.
=== SAS/SATA drives with power failure protection ===
A non-exhaustive list of SAS/SATA drives with power failure protection is as follows:
* Crucial MX100/MX200/MX300 (SATA)
* Crucial M500/M550/M600 (SATA)
* Intel 320 (SATA)
** Early reports claimed that the 330 and 335 had power failure protection too, but they do not.[http://blog.nordeus.com/dev-ops/power-failure-testing-with-ssds.htm]
* Intel 710 (SATA)
* Intel 730 (SATA)
* Intel DC S3500/S3510/S3610/S3700/S3710 (SATA)
* Samsung PM1633/PM1633a
* Samsung PM863/PM863a
* Samsung SM1625
* Samsung PM853T
* Toshiba PX05SHB***/PX04SHB***/PX04SHQ***
* Toshiba PX05SLB***/PX04SLB***/PX04SLQ***
* Toshiba PX05SMB***/PX04SMB***/PX04SMQ***
* Toshiba PX05SRB***/PX04SRB***/PX04SRQ***
* Toshiba PX05SVB***/PX04SVB***/PX04SVQ***
