Well, actually it does *NOT* support ATA TRIM. Instead, it has a bug whereby it reports that it has support for ATA TRIM, but in fact does not implement it.

Instead, it has a proprietary opcode and protocol to do something similar, but which is unsupported except with a clumsy little "wiper.exe" utility that runs only under a few versions of Windows.

Note that the drives are actually mostly just Indilinx designs, as is the "wiper.exe" thang, and there are at least three competing brands out there now with more or less exactly the same stuff.

Indilinx is apparently working on implementing ATA TRIM, but they've been promising (and failing) to deliver it for months now.
