SSD speeds capped in benchmark?

[Dario D.]

Can anyone make sense of this cap at 225 MB/sec? It's my brother's SATAII SSD (this one) being benchmarked with HD Tune. Pretty sure it's supposed to go up to 250 MB/sec, but there's this very odd "cap" effect happening here. (CPU = Core i7 920, Mobo = ASRock X58 Extreme, OS = Win7 64-bit)

Hmm, nevermind, this seems in accordance with Tom's Hardware's benchmark. Looks very odd on the graph above, though... as if it was being forced to stop at 225.

You can always try another program. HDtach, Crystal Diskmark, etc.

Controller card issue?

I tried Crystal Diskmark, and it reported an average sequential read-speed of 222.2 mbps. (just barely under the MAX that HD Tune was reporting)

Controller card issue?

No controller card in the computer. (SATA cables going straight to the board)
