WD Red SN700 NVMeSSD

[Enquiries]

I am going to purchase a DS920+ to use to store all of my movies and pictures ... I will start out with 2 10TB WD Red Pro hard drives and I want to get a couple of NVMe cards as well ... could I get away with using the 500GB card instead of the 1TB?

Yes, in-home environment a pair of 500GB is all you need.
When choosing NVMe for caching you need to look at reliability ratings such as DWPD/MTBF. Here are a few on the list

Caching means a lot of read and write operations, unlike regular storage situation.
You would need to look at models with 0.5DWPD and above

970 pro – 0.66DWPD
Seagate FireCuda 510 – 0.7 DWPD
Seagate FireCuda 520 -0.9 DWPD
Seagate IronWolf 525 – 0.7 DWPD
Seagate Firecuda 530 – 0.7 DWPD
Synology SNV3400 – 0.68DWPD
WD Red SN700 – 1.0DWPD

I hope this helps.
