Unofficial SSD Cache on DS920+

[Enquiries]

Hello gentlemen,

I have let the SSD Cache advisor run its course and it came back with a recommended 240GB Read-Write Cache. Unfortunately, the Ironwolf 510 240GB in the Compatibility List is not available in Amazon/EBay so I would like to search for alternatives. You have tested few unofficial RAM upgrade scenarios but I have not seen anything on the SSD Cache space. Any suggestions?

Thank you!

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.
