Are these any worse or better than a standard nvme for a nas?

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.

Seems these are still TLC, not MLC. Not clear what extra cash buys ...

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?

I'm not the most knowledgeable in this area. Synology seems to recommend that SSD cache be at least 2.5% of overall storage size, which would put you at needing >1.4TB of SSD.

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.

For a regular Joe type home NAS user... not much. If you're using a nas semi professionally and use these as a R/W cache the extra endurance is what you're paying for.

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

Yes the SN550 is a standard M.2 NVMe SSD, and the DXP2800 supports only NVMe M.2 drives

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

The 2TB Red is rated for 1300TB. It's the 4TB model that has the 2500TB rating.

don't do it. I have a synology and while i admittedly used non NAS rsted nvmes as read write cache, the scare made me never to do it again.

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.

Yes, you're right. I was fooled by the "up to" text even though I looked specifically at the 2TB version.
