Drive Performance/Stability

[AndAy224]

I just recently purchased a Corsair CSSD-F120GBGT-BK drive from newegg and ran a HD Tune benchmark on it. The results have me worried. I was hoping for another pair of eyes and an opinion of if I should RMA the drive. Thanks in advance.

i would run crystal mark test and atto test first before doing an rma. the problem with diag test is we dont know the file size and bit side of the tests. are they 4k reads are they random or next to each other do the test write 20 meg file to the ssd then read it back or is it a 40m file?? i have intel 520 ssd max speed should be 550..i was getting 340 with this test..less with crystalmark and atto under some test should i was getting the full 550. this like the drive bios and your os and the chipset drivers. and that you turned off or tweaked windows.

K what motherboard are you using, to me it looks like your using a sata2 3gb port for a sata3 6gb drive, just that differance alone will double your speed with that drive.

Thanks for the quick reply.
I'll test with ATTO and play with the settings and post back

I'm using an EVGA Z68 SLI and using it's SATA3 port and cable

have you played with the bios settings? Setting the ssd setting manually might helps aswell

Okay, did another test, and I was able to reach my 500MB/s from 128kb on up. Good or bad?

Use ATTO to verify manuf specs as that is what they quote.

Personnaly ATTO is NOT a good benchmark for SSDs, it was designed for HDDs and uses data that is HIGHLY compressable (Not even near real life)

Use AS SSD for two reasons:
1) It was designed for SSDs and Uses DATA that is NOT compressable, still not real life but much closer.
2) It will display some needed info:
... Firmware version
... Driver, Yours should be iaSTor (slightly better than default msahci), if pcide will also show BAD
... Will indicate if partition is properly aligned.
3) For Sanforce controller SSDs Seqquencial read/writes will be LOWER than advertised - THIS IS OK. Overall score should probably be in the 700. My M4 and Samsung 830 both get an overall score in the 700's

Side NOTE: Should not run benchmarks back-to-back, returned performance will decrease - Trim and Internal Garbage Collector need time to recove from all the writes.

So I assume with a score of 470, this drive isn't performing well?

1) see if you can google a review that show AS SSD overall score for your drive.

That score is about the same AS SSD overall score that I get with My 120 gig agillity III. Not sure what the performance diff is between yours and the Agillity III, but 470 is good for the Agillity III - It's just not one of the "better" Sata III drives. Infact I dub it a SATA II SSD in a SATA III wrapper. A review of it indicated that it infact does NOT perform any better on a SATA III port as opposed to being on a SATA II port (which I verified using mine on an i5-2500K (asrock Z68 MB) using the intel SATA III ports.

What version of Intel RST are you running, should be > 10.6. last I checked they were up to 10.8 and 11.5+ is suppose to add trim supoort for SSDs in a raid0/1 configuration.
