SandForce "SF-22XX" issues and workarounds

[Christopher]

The speed change you described is the variation you see to the default speed in Mhz? or it is the real speed switching from 2.49Ghz to 3.29Ghz. If it is the last one, then EIST is still enabled. Another thing to concern... most PSUs from today are focusing on 12V line. I guess SSDs are usually taking power from 5V line, as it is closer to their needs. It might be the difference between SSDs as others might use 12V instead of 5V one.

Yes, but the Seasonic X series uses DC to DC for the 3.3 and 5v rails.

Yes, EIST/Speedstep and Turbo are now enabled... but performance power mode is too. With all the power saving functions off, it was just sitting at the max non turbo ratio as it should.

I'd turn off TRIM if it didn't result in positively awful avg speeds. I'd be better off just living with the disconnects than running without TRIM. If I were having these problems but not trying to write 10+ TB a DAY, I'd not expect turning off trim to have much of an effect.
