HDD Upgrade For MacBook Air (1st Gen)

[CamFire]

Knowing me as a Mac fanatic, a neighbour of mine posed me the following question.

What are the upgrade options for a first generation non-SSD 1.6GHz MacBook Air? I know it uses a IDE/ATA 4200RPM 1.8" drive by Samsung. Is a 5400RPM replacement possible? Or a SSD ?

Cheers!

Not cheap but SSD is the way to go. Most users report improved overall speed with them. Can't see a faster HD being anything but a battery drain.
