Advertisements If anyone is looking for a good deal on a 1TB drive for an upgrade, Best Buy has the Hitachi external 1TB drive on sale this week for $279.99. Even less w/ a discount coupon It's a USB drive, not eSATA, but you can simply extract the drive - inside is a Deskstar 7K1000 drive. Case is pretty easy to open once you figure it out. The front slides off in a U after you depress two hidden tabs through the vents at the top and bottom of the case and slide forward. I didn't figure this out until after I forced the case open along the sides with a screwdriver. Note that according to the documentation, the warranty is voided once you open the case. Going to replace a 500GB with this in a Series 3 and put the old drive back in this case for my wife to use as external storage. Incredibly quiet drive too, and I haven't enabled AAM yet. Not bad, considering I just bought a Seagate DB35 750GB for a Tivo HD for the same price.
