Yesterday I placed an Intel 520 SSD in my Macbook Pro early 2011 edition. I removed the old hard disk and placed in the ssd, and installed windows 7 on it, without having OS X Lion installed. Even though my SSD performs admirably, it still seems like it's underperforming by around 200 MB/s for both read and write. I used the ATTO disk benchmark and at a transfer size of 128Kb, does it start listing speeds of around 290MB/s for read and 335MB/s for write. I looked around for enabling AHCI but this prevents the computer from being able to go to sleep, and I don't want this. Am I missing something? I installed the Intel Toolbox already and everything seems fine there. The SSD is running in IDE mode right now. I also installed all the drivers from bootcamp 4.0.
