Intel 510s 250gb RAID 0 - Very low performance

[idata]

Hello, 1st post here. I just bought a couple of these drives and picked them over Vertex 3 due to reliability. However I'm running a RAID 0 and getting rather low performance in every benchmark I've tested:

Crystalmark for example:

Seq read: 545, write: 453

512k read: 322, write: 416

4k read: 15, write: 30

4kQD32 read: 159, write: 100

Get very similar results in AS SSD

System:

This is a brand new M18x Laptop

i7 2920xm

8 GB Ram 1866

Windows 7 64

I did a fresh install, disabled the defrag and indexing

My stripe is 465GB and the Raid is configured with 128KB Blocks.

I did install the Intel Rapid Storage Driver

Any ideas?

Thank you.

Perfect, that's what I needed, just wanted to be sure Thank you let me do a test run.

Before test start thinking about rebooting!

Each Reg - change to the rescan.

Have you off SpeedStep?

Have you off C-states?

EDIT:

I've just seen your stats again from post one.

Please remember, the 510 series is not the best in 4k.

Your changes will not turn out so great.

You see this also in the "test-PDF" one of my previous posts.

Do not expect huge gains. If no improvement, then "LPM" turn back!

[idata]

Yup I have rebootet and all i did is the LPM fix

I notice no speed improvement

And Intel Rapid Storage still reports port 1 as 3gb/s

[idata]

Why Port1 as 3Gb / s is displayed?

Maybe there is your problem!?

A user in this thread had the same problem. (with C300)

After an exchange of this port was fixed.http://translate.googleusercontent.com/translate_c?hl=de&ie=UTF8&prev=_t&rurl=translate.google.de&sl... post16610939 See here.

In the Intel forum, there is also one this thread:

/thread/23997?start=0&tstart=0 Intel 510 SSD Seen as 3Gbs Drive

.

Whether it helps I can not say.

Your values with the "LPM" off are even less makes no sense.

Or is this at the other "benchmark program"?

Too bad I could not help you.

Yes the other benchmark I used is Crystaldisk...they are similar. I wouldnt say they went down.
