Seagate firecuda SSHD

Looking at these as my current drive is almost full. I've noticed there's a 2.5 and 3.5" version, is there any difference between them and if so what? I know it's not an SSD but will only be used for games and mass storage

The 3.5" one is bigger.

The difference is 1"

 

But seriously... thats about it. its just a shrunk down version of the same drive with (in most cases) similar or identical specs. the smaller 2.5" drives are usually more prominent in laptops, or some ITX cases where space and form factor is a much larger concern. As a result the 2.5" are often a bit more expensive, but when you need the reduced size the minimal cost increase is usually worth it.

Ah so they're different sizes?! That explains it ?

 

Thanks for the input and on this occasion the 2.5 is cheaper so I'll go with that

2.5" drives are typically laptop drives, they're smaller to fit into laptop bays and they also have different power optimizations as laptops need more efficient power management for portability and battery life. Just for comparison, here is what the spec sheets for the 2.5" and 3.5" FireCuda drives show:
 

2.5" (spec sheet here): Startup Current: 1.0, Average seek power for 2TB model 1.7/1.8 W and for 1TB and 500GB models 1.6/1.7 W, average idle power 0.5 W for 2TB and for 1TB and 500GB models 0.45 W.
 

3.5" (spec sheet here): Typical operating power for 2TB model 6.7 W and for 1TB model 5.9 W, Typical idle power for 2TB model 4.5 W and for 1TB model 3.36 W. It also lists a 2TB standby/sleep mode typical power of 0.75 W for 2TB model and 0.63 W for 1TB model.
