- Maximum Read: 285MB/sec
- Maximum Write: 275MB/sec
- Sustained Write: 250MB/sec

I wasn't expecting speeds to be exactly as stated above but I was hoping it would at least be close to the specs.
Do these two benchmarks look ok?

Write does seem a little low, is this a new install/drive? Running in AHCI?

Boozebeard · 22 Jun 2010 at 15:52

I hadn't done a benchmark on mine yet so I did one. My writes are even worse than yours!

What gives? No where near advertised. It's running in AHCI and using Intel RST drivers which were what was recommended on their forum D:

Mines only like 3 days old.

I did a second test and got just 48 MB/s on seq, what the F.

Ok, after a quick skim on the OCZ forums, they get their read/write speeds from ATTO Disk Benchmark which is what they recommend to use :\

So is that other one just plain wrong? Or is this benchmarker just some kind of cover up!

Apparently its to do with the Sandforce controller. The ATTO benchmark gives consistent results for all controllers.

Ok, I'm happy with my ssd again then

droyden · 22 Jun 2010 at 16:32

Thats annoying, I dislike the output of ATTO

Thing is though, what IS the real performance. Does Windows and apps use the SSD like the slower benchmarks or do they use it like ATTO? Is ATTO just a benchmark that satisfy OCZ's figures??

Hmm worth pondering

Windows boot time I'll have to say is the same or maybe even a tad longer than my previous 2 7200rpm in RAID0 (barring POST time).
However launching applications is much faster, MS Word opens up more or less instant, Adobe PS, OrCAD and eclipse 2-3 seconds each.

To be honest I think I had too high expectations for SSD. Buying the SSD was an impulse purchase.
Do I notice any difference over my RAID0 HDD? - Yup
Can I live without SSD - yup

Real world performance depends on how compressible/compressed the data being written/read is. Highly compressible data (text etc) , like atto uses, does well, uncompressible data (mp3, jpeg etc) not so well.

Zarf · 22 Jun 2010 at 17:11

Sandforce controllers store data in compressed forms, meaning less data needs to be written. This means less write cycles are used, and the more the data is compressed, the faster it can be read from or written to NAND.
Atto = Best case compression. AS-SSD = Worst case compression. Real performance is somewhere in the middle.

Windows boots much faster for me. Usually its done before the win 7 loading animation even finishes :cool:

What were you using before? As I said before I had to a RAID0 setup (~150mb seq read) so boot time there is little difference.

Boozebeard · 22 Jun 2010 at 20:41

I was just using a single 7200 rpm drive

thedazman67 · 22 Jun 2010 at 21:22

Mine arrived today just installed Windows 7 on it and Intel Rapid Storage Technology set to ACHI in the BIOS this is what I got. Are these results about right?

Boozebeard · 22 Jun 2010 at 21:40

Well as you will see if you read through the thread, that benchmarking utility is not good for benching this ssd. However I am still confused as to why I seem to have about half the seq write as you two in that test.

thedazman67 · 22 Jun 2010 at 21:49

Here are the ATTO results for comparision

Seems to be exactly what OCZ state me =

I suggest you run the ATTO Benchmark Boozebeard and then we can go from there to see if there is a problem.

Boozebeard · 22 Jun 2010 at 21:52

Oh, I did run the ATTO benchmark and got similar results to you two. Just confused why mine was much slower in AS and your two were almost exactly the same.

Did any of you guys used the original vertex tweak? I cloned my original SSD with installed tweaks and now i'm getting a freakish ATTO results. :eek:
