Merits of NMVe Cache with SSD Volume -M2D18

I am about to install a Synology FS1018 (purchased via your link to Amazon). It will have 24GB RAM. The FS1018 will host a RAID F1 SSD array (4x Samsung 860 PRO 240GB SSD drives) that holds about 100MB of performance-critical PHP apps and associated data caches – along with about 70TB of low-activity archived data on an attached DX1215 using 10TB IronWolf Pro HDDs.

Would an M2D18 with NVMe SSD likely improve performance (given an SSD RAID and plenty of RAM for cache)??? I’m not looking for definitive proof or benchmarks; but hoping to benefit from your general knowledge and, perhaps,the experiences of your readers/customers.


All SSD even in RAID0 will offer max 2000MB/s and relative IOPS. The NVME works at speed over 3000MB/s and much faster IOPS. It will definitely improve internal operations. The problem always is the weakest link in the chain. If you expect faster transfer speeds then no – you will be limited to 1Gbe or 10Gbe connection. Higher IOPS – definitely yes.
