Is the 3.5" means the size of the disc in the hard disk?
yes - in inches
I believe the naming is because the drive size is the same as a standard 3.5" floppy drive size. The 3.5" floppies were 3.5" wide and the hard drive is the same size, only longer (deeper).
that was the impression that I had - that it is to do with the width - across the front - ie the input ports are at the back,
the 2.5" are considerably shorter and not as long as the 3.5
the 2.5" are considerably shorter and not as long as the 3.5
huh.... so my comments were useless to you? And the answers provided weren't good? Can you explain why you gave a C grade on this - what other information were you looking for?
But seriously, the 2.5" hard drives are generally used in notebooks and some high-end blade servers. They are typically about the size of a credit card, only 9-12 mm in thickness. They also have smaller maximum capacities, I believe currently topping out at 120 GB where as 3.5" drives max out at 750 GB.
3.5" hard drives are used in most desktops and servers - they are about the size of a paperback novel.
