Seagate IronWolf Pro, 12TB, Internal Hard Drive, NAS, 3.5 Inch, SATA, 6GB/s, 7200 RPM, 256MB Cache, for RAID Network Attached Storage, 3 year Rescue Service, FFP (ST12000NEZ007)

I bought two of these drives to repair and expand my Synology DS215J, where one drive had become degraded. Installation was simple - remove dud small drive, insert new big one, allow it to repair - then repeat, replacing the second small drive. The *only* hiccup was the packaging. The drives came packed in sealed anti-static bags (yay!) but they were packaged together in a regular-sized 25x9x16 hinge-lid cardboard box that was probabably only designed to take one drive. There was foam wadding to protect the drives, but the box was bulging at the seams and was only sealed with a few strips of regular parcel tape over the lid closure. I should emphasise that despite this, they arrived in good working condition - but I expected a little more protection for just shy of £500 of technology.

Has good steady speed but is in the high speed test this was set as a Windows storage space in simple mode with 2 harddrives for games has decreased load times however was a pain that Windows didn't like it

The ironwolf series had always treated my well with my previous drives i have. Ended up taking a leap and went with 8TB of storage capacity for a external hard drive. Consistent speeds and very simple.

Still working years later

Installed these drive towards the end of 2019 and working perfectly in my server. Media player and data access is perfect in the raid array but

Put it in my Drobo RAID. Worked then, still working now 6 months later Transfer speeds 98% of advertised speeds

Good product
