Intel X25-E 64GB very slow performance with Alienware M17x-R2

I recently had my Alienware M17x - R1 replaced with the Alienware M17x - R2.

This is a screenshot taken from my R1 (nvidia chipset)

This is from my R2 (Intel Chipset, Dell's drivers installed for the chipset, Microsoft's default drivers for storage)

This is after a clean Windows installation with only the Dell chipset drivers and the latest RST drivers from Intel

This is in safe mode

Could someone explain to me why those numbers are so low compared to the R1? Is it Dell's fault or Intel's fault. I have tested the SSD and it's fine and I have also secure erased the disk before each clean Windows installation to make sure the SSD's performance is set back to factory defaults (8 secure erases and 8 clean Windows installations so far).

I have also tried every possible driver combination (Matrix Storage drivers from both Intel and Dell, RST, chipset drivers from both Intel and Dell) and I haven't managed to get the performance close to half of what it was with my R1.

Note, the mode is set to AHCI from inside BIOS, I get the exact same performance when Windows are installed with the RAID option instead of AHCI.

I am bumping this post, plus, I have to mention that the same low perfomance affects other laptops from different manufacturers with this chipset (Intel PM55)

Specifically for the Alienware M17x - R2 there are many users that report the same behavior with different SSDs as well.

Any suggestions are welcome (especially from Intel representatives)

I would like you to take a look at this as well and see how the real world performance is affected due to this problem

Interesting article, thanks. It's a shame you have not had any response from Intel or Dell. Have you tried getting through to an Alienware tech guy at Dell?
