Cache SSD Nvme

[Frricard]

Hello,

Do you have any feedback with the Nvme SSD cache on XPENOLOGY?

is it possible?

If I understand correctly, two disks are required ? because the cache is only done in RAID1?

which if it is the case limits strongly the choice of motherboards (ITX formats have only one).

or can we go for an additional PCI card like the M2D18.

Has anyone tried it?

Only possible on DS918+ DSM image with a patch, search for "NVME patch" and you will find it.  Normal rules apply - one NVMe SSD = read-only cache, two NVMe SSD = r/w cache.

 

SSD cache is quite overrated, it quickly wears out SSD's and adding RAM is often as effective with typical workloads, but if you really want to do it, it is relatively straightforward.  Haven't tested M2D18 but it ought to work with the patch at least.
