I looked incredulously at your dimensions of the 3.5 inch HDD, only to search for the correct ones and found the exact same specs on Wikipedia, then realizing that's probably where you got yours. Looking at hard drive manufacturers' sites, I see that that is in fact the correct dimensions.
What does the 3.5 inch figure represent, then? The size of the plates?
- c3o 16y agoThe 3.5 inch figure represents the floppy, remember that? :) A "3.5in HDD" is a hard disk that fits into the bay originally designed to hold a drive for 3.5" floppy disks.
- chancho 16y agoSo then why are laptop hard drives called 2.5in?
- SamReidHughes 16y agoBecause they're smaller.
- plorkyeran 16y agoBecause 2.4" sounds worse. (3.5 * 69.9 / 102 = 2.3985)
- megablast 16y agoI thought it wass due to the fact that the platters are 3.5", just as the 2.5" hd has 2.5" size platters. But no, looked it up, 3.5" have platter sizes of 3.74" apparently, 5.25" had 5.12" platters. Which makes sense when you look at a hdd with the top off.
