I have a 120GB Intel 520 as my boot driver in a Windows 7 x64 system running on an ASUS 5M88a-V EVO motherboard. The SATA is configured to run in RAID mode as I have a striped pair of storage HDDs. I am also using a single 1TB HDD, and a 500GB HDD in an ESATA enclosure. Something very wonky is going on with my drive speeds. In fact, I don't think it is limited to the 520, although that is the one I'd really like to get going.
The Intel Toolbox pops up with a message saying that it cannot find my 520, and that it will refresh, and then the program closes. However, behind this popup, I can see it displaying the basic information of the drive, such as SMART being on, etc.
Here is some info using AS SSD:
As you can see, the 4K64 Thrd is almost the same as the 4k. I read that it should be about 10X faster...
I installed the latest raid drivers from AMD to no avail. Hopefully I'm missing something.
If this helps, here are some 100MB benchmarks of the 1TB drive and the Raid0 (2x160GB HDDs) array:
