Intel 320 Series 080Gb SSD Low speed

Good afternoon. I installed this drive into your laptop Lenovo B560 and saw much reduced rate. Install all the drivers from the official site. AHCI mode is enabled. Tested the drive program CrystalDiskMark and saw the following results

seq read 218mb/s seq write 94mb/s 4K read 15mb/s 4K write 23mb/s After installing the drive in a desktop computer has the following results seq read 272mb/s seq write 96mb/s 4K read 30mb/s 4K write 63mb/s What could be the reason for this slowing down? Thank you. PS. Sorry for my English.

I experience similar 4K reads/writes in a Lenovo X201i (Intel Core i3-M330-2.13Ghz) on new installed 320 SSD 80GB (firmware 4PC10362).

AHCI enabled, all latest Lenovo and W7-32bit SW/drivers installed, CrystalDiskMark3.01b shows:

4k reads -> 14.9MB/sec

4K writes -> 23.2MB/sec

I am interrested to know what, in a Notebook infrastructure, the variables are that can case this decrease in 4K Reads/Writes compared to a Desktop or other PC.

I have the same problem on macbook pro 2011 (feb). See this:

I tried to contact Intel support but they are completely useless.

The interesting thing is that when I boot on OSx the drive feels a lot faster, as a matter of fact the booting time is just a few seconds. So I suspect there must be some setting under windows.
