I just bought an SSD to replace a failed hard drive in my laptop. It arrived 
yesterday. I measured the supposedly 2.5 inch drive, still in its plastic bag, 
with a measuring tape, and got 71 mm. Figuring that 1 mm is from the bag, I 
think we should call it a 70 mm drive. 2.5 in = 63.5 mm, so I looked for where 
the figure came from.

The 2.5 in turns out to be the size of the disk inside the drive. The size of 
the drive is actually 2.75 in × 100 mm (69.85 mm is an exact conversion). 
Since there is no disk in an SSD, the term referring to the size of the disk 
should be abandoned.

See https://en.wikipedia.org/wiki/List_of_disk_drive_form_factors for a table.
