Indeed. The weak CPU's are usually at fault there. Ok, they have the advantage of being relatively cheap and consuming only very little power, but on the other hand they always come short in the performance department as well. The new generation of NAS'es, like the aforementioned TS-509 pro and also the latest Infrant (netgear) model now use Intel Celeron CPU's which gives them a lot more punch, but forces them to consume more power as well... it's a delicate balance.

Ok, I'll bite. What's wrong with the NFS server that comes with these boxes? (stuff like this intrigues me since I'm now also step by step discovering the realm that is called Linux )
