I got (2) 7200.12 and set them up in RAID 0.
HDTach in Vista 64:
Average Read: 211 MB/s
Burst: 263 MB/s
Average read in the first 500GB of the RAID was around 230 MB/s.
I didn't test single drive speed, but all the reviews seem to be getting 107 MB/s in HDTach.
Other points... this drive runs cool, fast, and extremely quiet (I never here them). I highly recommend the Seagate 7200.12 series!
Miked, may I just ask what RAID controller you are using for those speeds. I have hooked up Raid-0 on a new pair of 7200.12's and am getting no where near those speeds. ~170mb/s max, burst of about the same too, admittedly performance across the 1Tb is good (i.e. flat and consistent) but I was a little disappointed (NVidia 630i Chipset) considering my Hitachi 7k1000.b has transfers of 120-80 and has a burst speed of 240mb/s
