NVMe for DS1522+

[Enquiries]

As per my previous request, I have purchased the Synology DS1522+. In order to maximise the performance of it, I would like to add 1 or 2 NVMe's. I have looked at the Crucial P5 Plus 1TB Gen4 NVMe M.2 SSD. Is this suitable for the DS1522+ (with or without a heatsink?) as I can't see anything in the specs as to whether the 1522+ is Gen 3 or Gen 4 etc. Please help if possible. Many thanks. Keith. PS Although this is for cache, will the 1522+ be able to use the NVMe for storage? K.

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

Synology SNV3400 – 0.68DWPD

Seagate FireCuda 510 – 0.7 DWPD
Seagate IronWolf 525 – 0.7 DWPD
Seagate Firecuda 530 – 0.7 DWPD
Seagate PS5 Game drive – 0.7 DWPD

Seagate FireCuda 520 -0.9 DWPD
WD Red SN700 – 1.0DWPD

I hope this helps.
