What’s the catch? This is the best deal I can find on the internet by a fair margin. This seller has an amazon store page as well and seems to have a good reputation on both. The seller claims its a new HDD from a reputable brand and offers a 5 year sellers warranty.
Ive had plenty good and plenty bad with seagate. Just for the sake of finding other drives here is a decent site ive used in the past… Diskprices
Also serverpartdeals
Both seem to have similar seagate drives around same pricing renewed so be curious of the drive is actually new.
