These are drives that were used only in reviews. Powered on for less than 10 hours. No warranty from Seagate. SN will be removed from top label. Very fast nonetheless. 15k7 600GB x 2 pcs, ns2 (10k rpm) 600GB x 2 pcs. Both are SAS drives.
The 15k7s go for $275 and the NS2 for $205 on ebay. Please make a fair offer. Thanks
