Reallocation warning message
Hello experts require some expert advice. two days ago after a disk test i got an email from my readynas 314 that disk 1 had to be reallocated and it later added this could mean a disk is failing...

today i downloaded raidar 6.5 and it gave a number 1688 reallocation errors on disk 1? is it time to replace a new disk then?
Definitely it is time to replace it.
Opinions on when to replace a disk vary. Personally I will replace a disk before the reallocated sectors count reaches 50 myself. But everyone would say that ~1700 reallocated sectors is a failed disk.

Don't get a new Barracuda - several of those are now SMR drives, and aren't good options for RAID arrays.
If you want to stick with 7200 RPM, then I'd suggest a WD Red Pro or a Seagate Ironwolf Pro. Currently shipping models start at 4 TB, so you would need to go with a bigger size. Note you'll need to upgrade two drives to the larger size to get more space in the volume. The capacity rule is "sum the disks and subtract the smallest).
Other enterprise-class SATA drives would also work (WD Gold to give one example).
