Trim configurations

Trim can be used with the following configurations and features:

•RAID volumes (mirrored, spanned, or striped).

NOTE: RAID 5 (striped with parity) is not currently supported.

•Simple volumes (no RAID).

•Any combination of the above RAID levels across multiple devices, so long as there is at least one IO Accelerator in the RAID set.

•Multiple partitions on the same IO Accelerator device.

•NTFS and FAT32 file systems.

•Volumes with mount points (no <drive letter> is defined).

•Compressed volumes.

•Different cluster sizes, packet sizes, and sector sizes.

•Extended and shrunk volumes.
