Hello, buu!

It depends what you're doing with them.
for unmanged arrays allocation will take more time then for managed ones.
Iteration, however, can be faster for unmanaged ones.

If you'll provide more background to your question it will be possible to
give more concrete answer.

Not so much... managed arrays are stored sequentially, access is equally
fast. But managed arrays are subject to being moved by the GC, so you can't
pass them to unmanaged code without first making a copy or pinning.
