M.2 NVMe for DS420+

[Enquiries]

Hello, I would like to buy M.2 NVMe disks.
In compatibility list for my DS420+ is Samsung 970 PRO or IronWolf 510. These models are from previous series and have their succesors.

My question is: Should I follow compatibility list or can I use new models.

And what about WD (for example WD Black)?

Thanks

Yes, They are not strict with NVMe.
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.
