Is my SSD underperforming?

[theone1989]

ACHI is on in BIOS, TRIM enabled. 62gb out of 83 usable GB free. 1 month old, powered on 102 times, data read = 384gb, written = 128gb, health = 100%.

I am concerned that I am not getting the benchmarks @ http://thessdreview.com/our-reviews/corsair-f90-force-series-90gb-ssd-review-benchmark-evaluation/

the more you benchmark (ie. hammer with lots of writing) a sandforce drive, the slower it becomes for a period of time. if you want to get your speed back, stop benchmarking.

their benchmarks are probably on a brand new or freshly formatted SSD being used as a secondary drive.

the only strange thing i see is that first screen shot showing the transfer slowing down and speeding up. it should be more of a flat line. dont know what would cause something like that though. could be other processes using the disk or sandforce limiting speed because of the writes.

If you look at when it's slowing down. The X amount of GB where it's slowed down seems pretty much like how much data has been written onto the SSD. Around 27GB. (90gb rated, but 83 usable in windows)

Even so, I'm surprised the rest of the data didn't reach 265mb+

there might be a reason for my ssd's performance afterall, apparently it's not "aligned", I installed xp onto it first, then installed win 7 over it.

urgh, now comes the problem 1 month later.

Where you see the dips, there is real data present. Where you see max performance, that space is unutilized and thus sent from the controller and not the NAND.

Use CrystalDiskMark or AS SSD for a real test.
