    "This is 12TB of storage, or 6Tb as Raid-1(mirror). I wanted something that gives plenty of space, and with two drives 6TB each, I can have a backup to my backup with Raid-1 setup. ...I use it as a mirror/raid backup HD, which means it copies exactly the same data in both discs. ...It's a nice but slow backup raid hard Drive"

    "Great NAS drive!...I added this to two older Seagate drives to support RAID 5 on my NAS. It sync'd perfectly and is now the quietest drive in the array....I didn't realize how old they were and they were pretty much used 24/7. I put the new drives into my TerraMaster F2-422 and in a few minutes the new RAID 1 was built and ready to go. "
