Someone on here recommended a wb black cause they're good.
But there are some that go for 110 instead of the 200 that goes for.

I want to use it for proccessing like video game creation. autocad

I don't want to get slowed down cause I cheaped out on a hard drive, but i don't want to waist money ona markup either.
I'd like it to be quieter if possible to.

Generally, the cheaper ones are older models which have more platters for the same capacity (areal density is lower, which is a fancy way of saying less data is stored per square inch of platter). More platters means more heat, sometimes more noise, and slower transfer speeds (since the heads pass over less data per rotation).

To get exact numbers, you need to dig up the exact model number and search for review tests of that model. e.g.

  • ■ $120 WD2003FZEX uses 800 GB platters (so 4 platters for 3TB)
    ■ $220 WD5001FZWX uses 1.2 TB platters (so 2.5 platters for 3 TB - one side of the 3rd platter is not used)
Since the second model has 1.5x the areal density, you'd expect it to be about sqrt(1.5) = 1.22 or 22% faster on sequential...

thankyou. What's the quietest model you can recommend for my needs? I'll look into what you recommend.
