No there are 2 different sizes.

2.5" = some HDD (Hard-drives), and all SSD (Solid State Drives)
3.5" = more typical style of drive which you will find in most pre-built computers.

Check any make sure you have mounts for the 2.5 and not the 3.5 before you buy a 2.5 instead of a 3.5

Example of size differences:



Mounting point differences:



Note on this picture that the bottom 4 holes are mounting points for the 2.5 inch drive while the side holes are mounting points for the 3.5" holes, hope this helps, thanks.

Is there a way to check without taking apart my pc?

The wider one and thicker one is the 3.5, and the smaller 2.5, yes you should be able to tell if the hard drive takes up the whole bracket or part of it.

Agree with what's been said above. Just to summarise:

The standard size of desktop harddrives is 3.5"
The standard size of laptop harddrives and SSDs is 2.5"

Many newer desktop cases have both 3.5" and 2.5" bays because SSDs are very popular in desktops. If your desktop case does not have a 2.5" bay you can buy a 3.5" to 2.5" adaptor for under $10.


So yes, all harddrives will fit in all desktop cases, but you may need to buy an adaptor if you buy an SSD. (Or do what I did, and velcro it to the bottom of your case. No moving parts, so SSDs can be shoved anywhere).
