Should be better for 24/7 NAS usage. The 2TB Red has a TBW rating of 2500, as compared to 1200 for the WD 850x 2TB. In that regard, the Red is made to withstand twice as many writes over its lifetime.
Addendum. The Reds are MUCH slower than a typical PCIe nvme. But, for NAS usage the network is a significant bottleneck which means the speed difference will likely not be noticeable.
Hmm. Three thoughts that come to mind are how frequently you update your media library (if frequently, that's a lot of large writes), whether your m.2 slots support SATA versus the more common NVMe, and how replaceable the data is (more importance in high quality drive).
If you write over the drive a lot, your hardware supports m.2 SATA and your data is irreplaceable, these Reds may make sense. Otherwise, might not make sense for the premium.

Another question, these would be going into a QNAP system as a cache type of system with 4x14tb raid setup. I mainly use it for backing up photos and videos from my phone, important documents, etc. Would I benefit from these and what size would be optimal value wise?
According to QNAP, there are also minimum RAM requirements depending on your hardware and the size of SSD cache.
The Reds are probably a good idea for cache, as there will likely be a lot of writes. The bigger the cache the fewer writes but still… cache duty is likely write intensive.
