Increasing NAS capacity
Question from a non-techy person. I have a RN104 fitted with 4 x 4TB WD RED drives. Can I fit larger capacity drives (eg 6TB or 8TB) (as I understand it, the original documentation seemed to in...
The orignal documentation is based on the maximum drive size available at the time. Larger drives will work in your NAS, and the volume size will expand once you replace two. You did not mention what types of drives you currently have, but you should avoid those that use SMR, which includes most new desktop drives and the WD Red line. The Seagate Ironwolf, WD Red Plus or WD Red Pro are good choices. If the rotation speed does not match that of the existing drives, the NAS will complain, but there are no specifically documented reasons. With your lower-powered NAS, you won't get an added boost with 7200RPM over 5400RPM, anyway.

Thank you. I shall search for two larger capacity disks to start off with.
My current disks are labelled "WD RED" but the product number, WD40EFRX, corresponds to WD RED PLUS on the WD web site which is CMR. The product shown currently on the WD web site as WD RED is product number WD40EFAX, which is SMR (although, confusingly, Amazon claim to offer a RED PLUS CMR disk with that same product number WD40EFAX).
I wasn't previously aware of the difference between CMR and SMR: is the difference mainly write speed? Given the confusion over product numbering I am not sure how to ensure I get the right technology if I stick with WD (which I am minded to do).
