Just about to RMA my new WD 80 drive for a second time due to high whine and access noise. My P4C800-e supports Serials and I was looking to spend a few extra dollars for the performance. I've heard the serial ATA's can be noisy esp for reads/writes but in some of the reviews - esp Maxtor's they mention they are quiet. Anyone using either a Maxtor 120 serial or Seagate? Whats the noise like. Tried a demo Maxtor ATA133 80 with 8mb cache and the thing was completely silent compared to the WD. No spin noise and seeks were almost silent.
