A reliable, easy-to-use NAS
Arthur C. Clarke, author of the book 2001: A Space Odyssey, said that "computer writing is the most reliable... second only to writing in sand".
With this in mind, I bought an ASUSTOR Drivestor 4 AS1104T NAS for my DTP department, so I can keep a backup of my various PC workstations. RAID 5 management is a plus in terms of security, the interface is very easy to use and the programming of start-up or shutdown at weekends is a plus.
Combined with 4 x 4TB Seagate IronWolf disks, this is really excellent equipment.
