Hi I think that it should be an improvement over the stock drive for speed and noise . I have a ST9808210A 80gb hdd in my G4 powerbook Ti and it is quiet no drive noise at all, and over the stock 40gb hdd it is quicker even though the speed is suppose to be the same at 4200 rpm. if it is within your price range try it out I have no complaint and my powerbook is used for mail, photo shop, web and adobe,. vicki On Apr 10, 2006, at 10:08 AM, Tom R. no spam wrote: > Best Buy has Seagate ST960812A on sale this week for $70. > Per the Seagate website, it seems to be 4200rpm, 8MB cache, > 12.5ms seek, and I believe a 5 year warranty. > > Any reports, opinions, etc about these as a replacement in > a 1.2GHz G4 12" iBook?
