Depends on the working set and your amount of memory.

If it's just temporary storage then no, as most data won't even hit the

If it's more of a cache then partially. Updates will use write bandwidth

bandwidth as well.

the filesystem "bandwidth" is pretty negiable these days. Very close to
raw I/O + memory cache.
