It will.

Ugh. Not fun.
One thing I try to do as a rule is make sure I always have enough free
disk space to handle a second copy of my largest table (.MYI and .MYD
files) plus a few percent. Otherwise you risk running into problems
like this.

MyISAM files only grow when they need more room, and they only grow
enough to hold new data you're trying to insert. So it's linear.
There are a few bytes of overhead here and there, but that's not going
to be significant.
