Using a solid state in RN21400

[Bjohn1]

Hi Folks,

I have a RN21400 with 2, 2tb HDDs.

One of the disks is getting a high uncorrectable error count, so needs replacing.

May I replace it with a solid state drive, are these compatible?

If so, any suggestions/ links on which I could use.

(I have searched forum, couple of similiar questions but I cant even understand the answers)

Any comments gratefully recived.

Kin Regards

If the size matches, then you can use it.  But you won't get SSD speed unless you replace both drives.  Likely you will get a warning about a speed mismatch.

FWIW, the HCL only lists Samsung 850 Pro and Samsung 860 Pro models in this size range.  The 860 pro is expensive, I don't think the 850 pro is still available in this particular size.  Other SSDs likely will work, but at least some of them misbehave in minor ways.  For instance: https://community.netgear.com/t5/Using-your-ReadyNAS-in-Business/rn-expand-2065-Failed-to-get-device...
