SSD Write Endurance 25nm Vs 34nm

[Ao1]

With the Vertex 2. On the X25-M, your data showed only a 0.02sec time for the TRIM, right? So probably not an issue with an Intel SSD.

Not with the X25-M, but maybe the 320 is different.

EDIT; with the SF drive I think there is a clue as to what happens when TRIM is executed in that its the same for compressed or uncompressed data. I'm going to guess it's mostly due to the processor on the SSD, rather than the actual delete operation.
