Full height 5.25" drives are 3.3" tall. This number may be a little
easier to remember. Once you remember 3.3" you can calculate that
half-height 5.25" = full height 3.5" = 1.65". They used to call 1"
tall 3.5" drives "low profile" IIRC.
Incidentally, 3.3" is the height of two standard CD-ROM or DVD
drives. There was a full height 9 GB Seagate SCSI drive, ST410800,
which was sold at extremely low prices (~$35 - $50) back in (I think)
the late 90s. Some of the sellers weren't too careful about
disclosing that the thing was a full height 5.25" drive.
When the 410800 was released it was quite a bargain. It sold for
around $5000 at a time when other drives cost about $1000/GB and it
was soon available for $3000. It sounds a bit like an agitating
washing machine when seeking, but it runs fairly cool and seems to be
very reliable. Mine is still working...
