I can't seem to find info on this, but it doesn't look like the "trim" ATA command made it into this spec, which is a bit of a shame. This would allow the OS (well, the file system or some smart block layer) to mark regions of the device to be discarded, which would help avoid constantly copying data between banks in SSDs.
Apparently, Win7 has support for it, and on the hardware side, the latest OCZ Vertex firmware apparently does too. Last I heard, Intel are waiting until there's an official spec.

- pmjordan 17y agoThey can just make it a point revision or a standardised extension. There is no point in supporting this command on something like a hard disk, so it would always have to be optional anyway. It's quite possible the SATA 3 standard was too far along, or they wanted to make it an extension to SATA 2. So it's no big deal, but I'd still like to see this standardised ASAP as I think it will drive quite a bit of file system innovation.
