Your local Staples Store now has a US$419 Western Digital MyBook Premium Edition 1 one terabyte drive with a 32 megabyte buffer and 36 month warrantee on sale until November 24th for US$349.00 after rebates (oops, US$60 rebate WAS online-only and it ended 11/10, the US$10 instant rebate is what is in effect until 11/24)

The drive is also available at TigerDirect.com for US$369.99.

I did find that CompUSA has a Maxtor OneTouch III Turbo Edition one terabyte Hard Drive Array for US$299.99 after a US$100 instant rebate which applies to both delivered or in-store purchases. The drive has a triple interface (USB 2.0, FW400 & FW800), contains two 500 MB 7200 RPM drives with 16MB buffer and is capable of RAID 0 - Striping faster access or RAID 1 - Mirroring for greater security.) If RAID 1 is used, you will only have a 500MB drive available. The drive comes with only a one year limited warranty (US$349.99 at Circuit City after US$110 savings).

With Black Friday and holiday sales just around the corner, better deals might surface watch black-friday.net for the presales fliers. If you want to start your time Machine today, then that CompUSA deal is your current best bet. Although none of us in Pennsylvania can go to a store and pick one up because all CompUSA PA stores were closed back in late summer. (UPDATE: Thanks to reader RDonaldson who informed us that CompUSA still has a superstore operating in Robinson Twp S.W. of Pittsburgh).
