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.

Sorry I speak no English.
Search "LPM" in Google in your language. Maybe this is your problem.
Alternatively, http://www.derbench.de/index.php/hardwaretipps/1-haenger-mit-ssd-durch-ausschalten-von-intel-lpm-lin... here is a German site. In the bottom of this page contains information from Intel in the English language.
My advice: Do not use the automatic reg files!If you're technically savvy, then the three Reg-values change manually! The values can always be put back again.
Please give a feedback in this forum!
PS: Secure your system before!
Changes in the registry at your own risk.Here's a http://www.hardwareluxx.de/community/f227/haenger-mit-ssd-durch-ausschalten-von-intel-lpm-link-power... thread on this subject in German.

Thank you ricky but I don't think this is an LPM issue, I don't have any blue screens, lock ups, my issue seems to be around the SATA/Driver detecting my second drive as a SATA 3 (6gb/s) drive.

This has nothing to do with BSOD and lock ups.
Also, I had no problems.However, the brakes "LPM" 4K performance. And this is a small extent even under "SATA II".An attempt is worth it in every case.
Switch to SSD Port tentatively "LPM" offThen measure the speed.For me, "LPM" disabled.08-12-2011 06:25 AM
Ok fair enough, do the instructions in that link you posted apply to the Intel 510?
