It's not about writing too often, it's about the performance hit doing
a read/modify/write when there's no free blocks.  Like the 4k sector
problem, but potentially even worse.

On the other hand, it depends on how much writing your server will do
in service.  If you aren't writing large files, you won't notice much
difference, and the benefit of ultra fast random access is more than
worth it.
