Single Client Performance Wrap-up
I haven't reviewed a true consumer level NAS like the TS-421 for a long time.
All of the other units on the single user charts use Intel Atom processors and some even cost twice as much as the TS-421. The 421 delivers a solid user experience at RAID 5 where most users should set the NAS at.
The HD video playback performance of 50 MB/s is strong enough to watch a Blu-ray ISO across the network. The 4x HD playback performance of 40 MB/s means four different TVs can play HD content at the same time, all off of the TS-421.
