Seagate Exos 6TB HDD (5 drives: total 30TB) SAS 12gpbs used for home NAS [LOT]

I had total of 25 drives of 6TB Seagate Exos SAS drives (12Gpbs) that powered up my home NAS with 16 and 8 bays each (16 + 8 + spare). They have all been used moderately, but not too much. They were always powered up, but since it was home NAS, they were not in constant read/write operation mode (lots of idle time with perhaps few hours of actual operation a day in average). The drives are checked and found to be in excellent working condition. The drives are all identical in size and model (best for RAID group). The drives are all manufactured in 2018 and 2017 (no 2017 or earlier). Of the 25 total, 20 of them are now gone/sold, and I am listing the remaining 5 as a lot. They were all set to individual disk mode (no association to any RAID array so that you can start fresh). You will receive the exact same drives you see in the photos. Please ask any questions before buying. Thanks.

CAUTION: These are SAS drives (as I am sure you are aware), and they do NOT work on SATA controller.
