Under "Interface" choose "SATA 3 Gb/s w/AdvFormat".
Why not buy one and measure the performance yourself?
MS is trying to spread fear about XP becoming obsolete:
however, 74% of business PCs still use XP.
In my opinion, what also needs to happen is an enhancement
to the SATA protocol, to upgrade to 4k "jumbo frames"
during transmission: this will eliminate almost all of
the 10/8 overhead on every byte (one start bit and
one stop bit for each 8-bit byte).
The 10/8 overhead is THE reason why SATA/3G = 300 MB/second,
and SATA/6G = 600 MB/second (just divide by 10).
When I proposed this to the SATA standards organization
in Beaverton, Oregon, they wanted me to pay them to review it.
My proposal made news at benchmarkreviews.com here:
