How to tell if your NAS is slowing down (and how to fix it)

If you notice your Network-Attached Storage (NAS) running slow after months or years of use, you’re not imagining things.

But you don’t necessarily need to upgrade to a new NAS to fix that — sometimes, a few tweaks on the hardware or software side can make it feel brand new.
