I purchased a DM+9 at the Thanksgiving sale at CompUSA (Pricing fluke they had placed WD 800JB's on sale sign with no model info just "80 Gig, 7200 RPM , 8 Meg Cache, $99" or pretty close to those words. Naturally most would select newer technology, other things being equal, and I grabbed the Maxtor. The checkout price was different and short story long I got the Maxtor for $10 more than the JB, I thought it would be worth it so I went along.) I installed the DM+9 and I am very happy. It moved a IBM GXP 60 40Gig drive to another computer. I am happy with this Maxtor! My IBM's were very good to me, but the Maxtor was a step up. Fast and quiet.
