So I bought some SAS HDDs from eBay for dirt cheap, and first thing I did was to look at its SMART reading. Here is an example:
Very different from SATA drive's reading. Manufactured years ago but with few hours, looks like new old stock. Got a few ECC corrected errors, but no unrecoverable ones (I believe consumer drives only report the latter?). All looks good to me.
What is bugging me is that the model# H7240B520SUN4.0T is different from the physical lable, which is HUS726040AL5210. Maybe this was made by HGST for SUN, but SUN was bought well before the drive was made. Also it feels wired to have different #s on the label and burned in.
What's your thoughts on these drives?
