Seagate Hard drive issue

[Heusen77]

hey
what is the difference between:
Seagate Barracuda 7200.9 250GB 7200 RPM IDE Ultra ATA100 Hard Drive - OEM and

Seagate Barracuda 7200.7 250GB 7200 RPM IDE Ultra ATA100 Hard Drive - OEM

I want to buy one for my Dell Dimension 4600 but not sure which one to get. Can anyone help?

no real diffrence between the two, the 7200.9 is the newer model. but if it were me I would just buy the cheaper of the two.

The 7200.7 is a known reliable model, I know some of the 7200.8 series had issues, the 7200.9 replaced it and so far seems better.
