    Older drive with smaller cache, 64MB. Newer drive (FAX Model) has 256MB Cache.

    The newer FAX is likely SMR and hence the 256MB cacche.

    Could be. But the FAX model has considerably faster right speed 180MB Vs 150 MB per second.

    I wouldn't necessarily trust vendor published performance specs. I made the decision to purchase the tried and true FRX model during Amazon's storage sale a few weeks ago. WD still sells both models for the same price. I don't see WD doing this for any other reason other than cost cutting - switching to SMR platters but needing to increase cache to maintain write performance. Other drives at this capacity with 256MB cache are mostly if not all SMR drives. Unfortunately I haven't come across any published performance benchmarks for the FAX model to confirm if it's indeed SMR.

    Any tips on how to give a go at buying/building my first NAS? Like, if I bought this, what what I put it in? I'm not as dumb as this question sounds, but not an IT professional.

    I actually ordered one of these instead of the newer smr drives, its fast. That extra cache does nothing really for normal use...

    Bought 4 last time around. Excellent drives. Much quieter than the old Toshiba (Hitachi) drives I was using.

    All late Jan 2020 stock and the newer 68N32N0 models which IIRC use 3 platters instead of 4 - more reliable with fewer reports of failures.

    Looking to setup a NAS for small business.
    Suggestion on an enclosure for this?
    Should I buy a couple so it can be a RAID setup?

    You should probably do some research before buying anything. You are asking very basic questions.

    Anyone using one of these in a normal desktop pc either as a homegrown NAS or otherwise? Bought one at one point due to the SD effect and never built the NAS I planned to. Have an old PC I could use as NAS, or I could just throw it in my desktop gaming pc for storage. Thoughts?

    look into UnRaid - it's pretty simple to setup - even though it's based on Linux... i've been running it for almost 10 years now. And it is rock solid, great support, has lots of plug-ins (dockers), and even runs virtual machines so if you already have a machine, this can add utility to that.
