Does anyone have an Intel-based SSD they could spare?  :)

Rumour has it they they do not comply with the ATA-8 spec for TRIM,
in that they don't support more than one "sector" of range data.
The SSDs I have here all support much more than that.

Still, even if we just do a single 512-byte payload of TRIM ranges,
it would be a huge win.
