Personal anecdote: I have had an old Synology DS215j using WD Blues for about eight years now, and the SMART checks show the drives are within spec.
First, I’d go with making sure you have 3-2-1 protection. It is better to have RAID 1 with two Blues than one enterprise drive. If you already have 3-2-1 protection in place, then move to higher tier drives.
Focus on the backups and getting that in place first. Ideally, CMR Reds are what you should be using, but if money is tight, blues can work.
