 While Windows 7 supported automatic TRIM for internal SATA SSDs, Windows 8.1 and Windows 10 support manual TRIM (via an "Optimize" function in Disk Defragmenter) as well as automatic TRIM for SATA, NVMe and USB-attached SSDs.Solaris as of version 10 Update 6 (released in October 2008), and recent versions of OpenSolaris, Solaris Express Community Edition, Illumos, Linux with ZFS on Linux, and FreeBSD all can use SSDs as a performance booster for ZFS.A low-latency SSD can be used for the ZFS Intent Log (ZIL), where it is named the SLOG.
