OK, here is an OCZ Solid-3 60GB on an older i7-870 System with a SATA-II controller.
Also there is a Kingston HyperX 120GB SATA-III in the same system, and on the same controller. Scores are nowhere near some of the best posted here. But real world usage is great. System is a lot faster with them in here. Getting ready to put a 2TB Seagate HDD in it for meaningful storage space.
