I knew as soon as I made that post that I had the wrong case for the b.... But I'm a lazy SOB, and had other things to do, so didn't edit...
Does Seagate now make a cheetah in SATA format?
Anyway, back to practical matters.... I was bored one evening, so tested my 150 GB Raptor with HDTune then tested a Seagate 7200.11. I saved the results. Raptor is definitely a bit faster overall, but most so in small file reads / writes where the access times actually make a difference.
Then for grins, I re-did the tests with the 150 jumper installed.
No real diference...
Two things I learned.... 1. Either modern SATA controllers ignore the jumper settings, or (more likely) current drives cannot saturate the bandwidth in 150 mode. 2. Raptors are really not worth the money...
