Slow speeds with Intel 510 SSD series in MBP Late 2011

I recieved my MBP 2,2 Late 2011 yesterday, and popped in my Intel 510 Series 250 GB SSD. This machine was a replacement for my defective mid 2010.

I figured the SATA 3 speeds would provide me with a decent performace boost, but at this point I have only seen some minor improvements.

The theoretical read and write speeds are 500 and 315 respectively. So far I have only seen a max of 310/170, which is just slightly above what I saw with SATA 2.

The system profile claims a negotiated speed of 6 Gbit/sec, and I formated the drive before I installed Lion.

All suggestions would be greatly appreciated :)

I have an 520 Intel SSD. My speeds are greater than yours. Maybe it is because yours is 510 series while mine is 520.

Your read speeds are above what that drive is specified @ SataII which confirms the drive is working @ SataIII speeds as indicated. What benchmark are you using to provide those figures?

Thanks for the reply. I get the same figures with both Xbench and Black Magic Disk Speed Test.

Exchange the drive with a 520 model :)
That is a little bit easier said then done, I am afraid :p. Seriously though; might there be something wrong? Or is this simply what I should expect?

Are there not someone with the same drive who are able to shine som light on this?

Blackmagic Disk Speed Test uses incompressible data so the speeds are always lower than the advertised speed by as much as half.
