Low speeds on Intel SSD 520 480GB model

[idata]

Hello

I recently bought this model and I believe I set up everything correctly.

I switched to AHCII mode before I freshly installed win 7

After that I installed Intel(R) Rapid Storage Technology Driver Software V10.5.0.1026 and SSD toolbox v. 3.0.3

I also tried few other drivers and different setting combos but I keep getting:

275MB/s read and 195MB/s write results in AS-SSD bench. It also says: pciide - BAD, although I installed everything in AHCII mode.

I am also getting another prob with SSD toolbox... When i try to start SSD Optimizer it stops at 5% and gives me: "Error: The Intel SSD Optimizer encountered an error (40). Reboot and try again."

I can't figure out where the problem is. I have Asus Rampage III Extreme mobo which has Marvell® PCIe 9128 controller, but I don't think lowlpthat this is the reason for such a huge performance drop.

Would appreciate some help and suggestions here...

Thx

It's not a calculation, it's simply the reality of the SATA III interface. Well known in the PC community.

Have you asked your question on your mother boards forum?

When you find a SSD that provides 600MB/s on a Marvell SATA controller, let us know...
