What speeds are you getting out of it?
More than twice the speed of the original Mac mini hdd wich was 34643 KB (Hitach 5400rpm 80 GB)i and with the Kingston (SMS200S) I got 78407 KB/s with the programI used for testing (MasterISO - for some historical reasons).
That's pretty fast. Just ordered a 256GB mSATA SSD and IDE enclosure/adapter. Can't wait! I am getting around 9MB/s out of my SSD connected to the Vampire 500
