Double check to make sure the box next to "Turn off Windows write-cache buffer flushing on the device" is not checked. Having this option selected will put your filesystem and any important data stored on the drive at risk in the event of any external interruptions such as power failures. With that said, if you are not concerned about data integrity and only want the fastest SSD performance possible, enabling this option may provide the speed boost you crave. I say may because this seems to vary from drive to drive and system to system (Intel recommends to not disabling write-cache buffer flushing on their drives). Benchmark your SSD with it enabled and disabled to determine if it provides any benefit.
Check and Enable or Disable SSD TRIM Support in Windows 7 Windows 8.1
You can run a certain command in Windows 7 that will show you if TRIM support is enabled. Run this command from an elevated command prompt in Windows 7: fsutil behavior query disabledeletenotify. In this case the return DisableDeleteNotify = 0 means TRIM support is enabled in the OS (which is Windows 7 default, even on 'normal' hard disk drives).
Since Windows 7, the TRIM is enabled by default but might be disabled due to some reasons. Therefore, users still need to check whether the feature is enabled: run CMD as administrator and type fsutil behavior query DisableDeleteNotify.
xfsprogs 3.2.0 has introduced a new on-disk format (v5) that includes a metadata checksum scheme called Self-Describing Metadata. Based upon CRC32 it provides for example additional protection against metadata corruption during unexpected power losses. Checksum is enabled by default when using xfsprogs 3.2.3 or later. If you need read-write mountable xfs for older kernel, it can be easily disabled using the -m crc=0 switch when calling mkfs.xfs(8):
