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.
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.

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.

I use a single 1tb m.2 in my nas, it is basically for docker apps and another backup location for any critical items. Edit: non-red ssd

I had drive failure after about 3 years of use. The thing is, once your nvmes fail, the system goes into lockdown mode and does not allow you to read data until you fix the nvme.
But wait, the drive "died", so how to fix?
reddit said to place a different nvme and see if you can temp pass the checks before it crashes again.
I basically did this, but in order to disable read wrote cache i had to uninstall a bunch of programs to fix. It wqs weird and took me 2 "surprise" hours and a lot of worrying.
Experience scared me straight - not worth it.

How is the SN550 relevant to a deal for the SA500, which is SATA???
