I have a 4-year old Asustor 4-bay NAS. 3 6 TB disks are set up in a RAID 5 configuration, originally they were all WD Red disks. Now, during the last couple of months I've had 2 of the disks failing (bad sectors and a couple of other S.M.A.R.T errors). I've replaced them with 6TB Red Pro disks, I thought that made sense, because they seem to be a bit more reliable (5 years warranty in stead of 3 yeras fopr the Reds). They also come at 7200 RPM in stead of 5400, although I won't notice a difference until I also replace the 3rd Red. (Or perhaps I won't noitice the difference at all).
However, now I see on the internet that the Pros are really not recommended for so small NAS'es, so maybe it's a waste of money. And I would probably see better performance if I install an SSD disk as a cache for the RAID, which the ASUSTOR supports. And even more important - do I actually need better performance from NAS. Unfortunately, to be honest, I'm not sure I can justify saying yes to that question,
A couple of questions:
1. The NAS is on 24/7. Is 4 years a reasonable durability (correct English?) for a standard NAS disk?
2. Would you recommend going for a Red Pro if/when the remaining Red fails.

PS. BTW, it's actually quite fascinating how easy replacing a RAID disk is, I just take out the offending one, and put in the replacement, then the NAS takes over rebuilding the RAID. No need to turn off the NAS or releasing it in the admin software. Initially I couldn't believe it was that easy, but it actually is. DS.
