Best NVMe M.2 SSD for caching
Hello, so I have a DS1821+ that I use for my Plex file station, I use a pc for the server itself. I do know my metadata folder is closer to 800 GB. I am looking to install a NVMe SSD for cache. I do not know if the models that are not listed on Synology’s capable list will work. Furthermore, I do not know the recommended size to get, I was thinking 1 TBx2. Can you please advise.
Samsung 970 EVO Plus 1TB M.2 NVMe Internal Solid State Drive (MZ-V7S1T0B/AM)
Samsung 980 1TB NVMe PCI-e Internal Solid State Drive (MZ-V8V1T0B/AM)
Silicon Power 1TB PCIe Internal Solid State Drive (P34A80 NVMe PCIe SSD)
WD_BLACK 1TB PCIe Gen4 x4 Internal Solid State Drive (WDBAUY0010BNC-WRSN)
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 530
Seagate IronWolf 525 – 0.7 DWPD
Seagate IronWolf 510 – 0.9-1.0 DWPD
Seagate Firecuda 530 – 0.7 DWPD
Seagate FireCuda 520 -0.9 DWPD
Seagate FireCuda 510 – 0.7 DWPD
Synology SNV3400 – 0.68DWPD
WD Red SN700 – 1.0DWPD
I hope this helps.
