Thread:Project:Support desk/Is Running a Wiki on a Stick Slower?/reply (2)

A USB stick usually contains a SSD (and not harddisc with rotating parts). SSDs are much faster than old HDD drives, but to be faster, they must be conected as a harddrive. When you use a USB port, this will be notably slower than any internal device; also slower than an internal HDD. If you have the choice, you get the fastest results with an internal SSD.

However, apart from the purchase advice you might want t start backing up your stuff regularly. That way you won't have to strt over again in the future.
