What is the difference surrounded by a 2.5 or a 3.5 external complex drive cage skin.?

I enjoy a 40 gig complex drive I took out of an old workstation.
I want to make it an external strong drive but don't know what kind of storage area to buy.

Answer:
If you took the hard drive out of a notebook/laptop, you'd have need of a 2.5" case.

If you took it out of an weak Desktop pc, you'd stipulation a 3.5" case.

Also, while nearby are some exceptions to this rule, generally you'd obligation an enclosure that contains an "IDE or EIDE to USB" nouns. 90% of PCs made before a year or two ago contain IDE connectors.
Get the 3.5" storage area. This will accommodate an optical drive (DVD/CD type) or a desktop size hard drive.
The 2.5" enclosure are meant for laptop not easy drives, which are much smaller than a desktop hard drive.
you will want the 3.5 enclosurse...
