OCZ Vertex 2 Slow Speeds

[RandomSanity]

So I recently took the plunge and installed windows 7 to a nice new OCZ Vertex 2 and was extremely unimpressed by the speeds, this thing feels slower than my old 5200rpm samsung.

I ran AS SSD benchmark and confirmed a lousy score compared to what others with this drive have.

Score: 52, 135, 222

Does anyone have any recommendations on why this might be the case?

Thanks!

Are you referring to the write caching? I have that disabled of course and the performance of my drive is abysmal compared to these others.

Benchmarking the SSD degrades performance until GC has time to fix the drive. AS-SSD is the most painful of any benchmark tool.

Can you please elaborate? My performance is very poor and I will stop benchmarking if there is a solution available. I am getting less than a third of the speeds most users see on this drive.

It was in the link grimpr provided. Read around those OCZ forums and you will learn alot.

That is the problem, I have read all that prior to installing the drive and have followed all of the steps exactly. They actually recommended benchmarking the drive and I have done so and found very poor performance compared to others.

Don't run benchmarks.

Post from the link:

Here is the thing, if you hammer the driver with say enough writes that the drive would under normal use/see in 7 days within a few hrs, the drive will slow down for 7 days, maybe longer. It does this to protect the nand life. So your guys seeing a 50% drop may actually see 30% which is the normal drop, then a further 20% because at some stage they have hammered the drive and then not realised its going to take 5 days or longer for the speed to creep back up. Also remember this write quantity slowdown is further impacted by how you use the drive after you have hammered it."

Try the benchmark OCZ and Corsair recommends for SF Controller drives,ATTO, and post here. You could also copy paste some Winsat numbers, open a cmdline and run winsat disk. Crystaldiskmark and AS-SSD are NOT suitable for SandForce drives, dont run them.

Sorry, I was thrown off by the hundreds of AS-SSD benchmarks posted on the official OCZ forums. So ALL of these people should be experiencing less than 50% speeds? Why then can they run repeated benchmarks receiving speeds of over 250mb/s while I can't run one and get over 110mb/s I simply have trouble understanding this.

ATTO will not have the same negative effects on the drives?

Thanks.

Im in the same boat with my HDD Now even with 512k I get low benchmark scores. But initially when I converted from 4KB to 5k I got high scores. Now if only I can change cluster back to 4KB then change that again to 512k would might fix my problems. I use Partition Wizard and it says not enough free space. Is there a app that doesnt care how much space you have and can change me from 512k to 4KB then back to 512k and see if I regain my speed.

@4KB

At 512k cluster

Very similar to my results 🙁 You have any idea what is wrong? Bad batch maybe?
