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.

I forgot this is all on a laptop! Now that is a laptop, so often you see the low performance of low to mid priced laptops, and I forget there are a few that have really good performance. You do have the top of the line Sandy Bridge mobile CPU, and equivalent chipset. Do you know if you have the HM67, or the QM67?

Actually, the 510 is not quite as power efficient as earlier Intel SSDs, 0.001 watt is unheard of, but it uses up to about two watts, according to this review anyway:

That is the price of the SATA 6Gb/s interface.

Better keep an eye on that PC, so it doesn't disappear!

Thanks man! yeah it leaves my desktop in the dust this laptop. As far as power c. I was refering to Ide, of course fully load it's no where near that hehe (would be nice though)

As far as the CPU not sure, I know I have the 2920XM thats about it, it does OC very very nice, with Turbo up to 4.2Ghz is my Max so far but I don't want to push it too hard (no real need)

You're not sure about the CPU?! I am, that is the top of the line, Extreme Edition Mobile Processor, with a price tag to match! Spec-it-out:

Intel doesn't even spec the (so far) best desktop Sandy Bridge CPUs for 1600 memory. It would be interesting to try this CPU in a custom socket mother board in a desktop environment.

You could try disabling EIST and C-States, for that 4K Read performance, if the BIOS lets you, on laptops (I don't think your's qualifies as one... performance-wise) power saving is always a priority. At least the BIOS let's you change the Turbo 2.0 multipliers. You could also try the Windows power options, such as select the High Performance plan and tweak some things in the Advanced options, but those likely won't change EIST, etc.

BTW, are you using the on-board graphics? That is likely a stupid question, but just curious.

Sorry it was a typo, I meant not sure what Chipset this lappy has exactly. The CPU is awesome no doubt.

My BIOS does not have that level of detailed options....

Here are my full specs:

i7 2920XM @ 4Ghz (factory) | Dual GTX 580M | 8GB DDR3 1866 | Dual Intel 510 256GB RAID 0 | Killer Wireless-N 1103 | Blu-ray | WirelessHD | Win 7 64 | nVidia 280.26 drivers

However I do use the on-board GFX when I want to sqeeze extra battery, but I'm usually plugged to the wall with this beast as you can imagine lol
