In these days of cloud storage, it could be worth it looking at offsite backups to the cloud. I would suggest a minimum of at least two backup sets, on rotation using either USB drives or tape, with one of the sets kept offsite. Just remember, while RAID allows for some fault tolerance with drive failures - it isn't a backup strategy on its own! If you are storing business/irreplaceable files then you need a NAS with backup capability and a good backup strategy, and ensure that you stick to that strategy. The rebuilding of a RAID could loose you more than the disk that already failed since its a fairly heavy procedure on the disks. If the data is really important to you (and not often backed up to other systems) it could be worth it to set it up as a RAID 6, where the RAID should survive a 2 disk failure. Plan is to populate with 4x4 WD Red drives in RAID5 (for 12TB usable with some fault tolerance). ![]() So there is a big difference, and it could be worth the money to look at importing from the US or UK. ![]() Have been looking at prices for a new 5-disk bay for my Synology D1512+, and the prices in NZ is around 990 NZD, in the US that same unit cost only 575 NZD (Plus shipping and GST). The pricing on most NAS units in NZ seems broadly comparable to what you pay for the same unit in Oz etc, except for QNAP where the difference seems huge. I was looking at QNAP, but their models seem to be either underpowered or (for the larger ones) overpriced.
