Deskstar T7K250 Highlights Capacity - 250GB and 160GB Rotational Speed - 7200 RPM *** Interface standard - SATA II 3.0Gb/s (Serial) and ATA Ultra 133 (Parallel) ATA-7 streaming feature set Average seek time - 8.5 ms Same drive, different interface. This has been the case as long as I've been checking out specs. If your drives are that bad, try another manufacturer. Are IDE drives more unreliable? They cost significantly less, spin at lower speeds are are and are a mass-market item. Some of the cost difference is interface complexity, the rest, I'm sure, is that SCSIs tend to manufactured to higher tolerances. Ask owners of an IBM Deskstar 75 how reliable an IDE drive is :-) (Then duck). --Alex
