I’ve found these two drives that look good but can’t choose. I’d use the drive mainly just to store games and videos. The problem is, as aforementioned in the title, I don’t know what is a better deal.

 

Drive 1: 2tb, 7200rpm, 256mb cache, $55usd https://www.newegg.com/seagate-barracuda-st2000dm008-2tb/p/N82E16822184773

 

Drive 2: 3tb, 7200rpm, 64mb cache, $65usd https://www.newegg.com/seagate-barracuda-st3000dm008-3tb/p/N82E16822178994

 

Advice would be appreciated

I got the 3tb model. Gettin' around 120-130 MB/s read and write with around 340 GB free space on it. I keep it defragged though but not too bad speed I think. Believe I've seen 170-190 speeds with more free space but don't quote me on that.. 😛

 

I'm looking for another one to raid my current one actually but can't find it here anymore..

More GB per $ is better.

Both drives are fine. I own at least one of each. My ST3000DM008 gets about 190MB/s reads and writes. I don't have any blank ST2000DM008 drives handy (I do have some in use though), but they're very similar. For your needs the 3TB model is fine.
