Re: Is there such a thing as a slim HD?

The message <Xns9A6EBB788F873meremoveallthistextc@xxxxxxxxxxxxxxx>
from Davy <me@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx> contains these words:

I tried to install a 230Gb Samsung IDE drive in my IBM M50 8187 but found
that it was too thick to fit into the hard drive slot available. The
factory installed SATA drive was much thinner.

Are there standard thicknesses for hard drives?

Yes, for 3.5 inch hard disk drives, the standard is 1 inch high. This
allows the drive to comfortably fit into a 1/3 rd height drive bay (full
height being 3.33 inches), which, according to the specs on that model
of IBM is what the internal and external 3.5 inch drive bays are
specified as (1/3 rd height, that is!).

The only 3.5 inch hard drives that exceeded the 1 inch height limit,
hark back to the days when 157MB was considered leading edge (although I
did see a full height 1GB drive when a price tag of £700.00 was
considered cheap).

I've seen the 1/6th height varients from time to time, mostly (if not
all) being the cheap 'n' nasty Exelstore brand. I suspect the 1/6th
height limits the strengh of the voice coil magnet that can be used
which compromises the seek performance.

The use of a 1/3rd height housing in the case of a single platter drive
where a 1/6th height housing would provide ample room is probably to do
with production cost savings, as much as to avoid seek performance
issues.
