Has anyone done any comparison between a new HD and a refurbished (RMA'd) hd of the same model?
I've had the unfortunate luck of having to RMA 3 different HD's lately. One WD, one Maxtor and one IBM. all 7200 rpm.
Before they went back, on the same system under the same conditions, I recorded the sandra HD benchmark on all 3 HDs.
After I got them back from the RMA dept, I re-benched all 3 HDs. Although the RMA drives work fine, there seems to be a significant drop in performance. As much as 70% decrease in performance.
As I understand it, mfgs may need to map bad sectors on a platter to unused sectors during the refurbishing process. This mapping will cause extra head movement and thus more seek delay and poor performance.
I see many people selling RMA'd hds as if they were almost as good as new (many mention the fact that the drive is still sealed in antistatic bag fresh from RMA). When infact the drives are no where near as good as new. and the prices of these "fresh" RMA drives aren't that much cheaper then a new one would be.
Has anyone else noticed a big decrease in performance of RMAd HD's, and do people who buy these "fresh" RMA drives know that they are paying nearly new price for a drive that will perform noticeably worse then new?
Just curious that's all!
thanks!
