Yep! There are only two drawbacks to microdrives:
- Slower than real flash
- Can't use 6000+ feet above sea level (lack of air pressure can make
the drive go wonky or, rarely, break it)

I have to strongly dispute this; The IBM (later Hitachi) MicroDrive was
rated at 10K feet. I did competitive testing on it and the Seagate 1" drive
and both had no problems at 10K feet. In fact both + the WD 1" drive work
fine well past 10K feet.
Come to that, Maxtor, Miniscribe, IBM and DEC built drives in Colorado well
above 6000 feet. Apple used to have a factory at Fountain (6400 feet). So
this simply isn't true. The biggest customer of the MicroDrive - Apple
iPods - work great on the ski slopes. They also work great in Reno at 7000+
feet. I can personally vouch for this and I'm certain others on the list
can too.
They also work fine on airplanes, which are pressurized at 8000 feet.
I have never heard of a drive breaking because of altitude. Rarely, you get
a head gimbals or suspension problem that doesn't like 9000+ feet. But that
is a defective drive, not the rule.
All drive vendors and many OEM buyers do extensive testing to ensure this.
And all heads are testing for flying height before being installed in a
drive.
Finally, today's drives utilize Dynamic Flying Height technology which uses
a heating element in the head to maintain constant controlled flying height.
Altitude is not a problem with any drive on the market today.
