The current standard for 3.5" hard drives is 1" tall, but in the past there also was a half height (1.63" tall) standard as well.

I'm thinking with multi-actuators on the way the taller 1.63" drives have a higher chance of making a comeback.
If not 1.63" at least 1.5".

3.5" form factor drives come in two general profiles: the larger is the so-called half-height drive, which is 1.63" in height. This name is kind of funny, since it is "half" of a height that never existed for 3.5" form factor drives. The name was derived from the fact that these drives are the same height as half-height 5.25" form factor drives, which are half the height of full-height 3.25" high drives in that form factor. Half-height 3.5" form factor drives are still used today, but only in servers and other high-end platforms. The standard for 3.5" is 1" height, which is commonly called slimline or low-profile, but just as commonly given no name at all and assumed as the default. The reason for the smaller size being the standard is that 1" is the height of a standard 3.5" floppy disk drive and 3.5" drive bay. In addition, there are some drives that are reduced in size from the 1" standard, using for example 0.75" height.
