NAS - WD Ex4100 vs Qnap TS-451

[MrFeetZ]

In market for a new NAS and have it narrowed down to either a Western Digital EX4100 or QNAP TS-451. Both are priced pretty similar. I will be getting the disk-less version and starting with two new WD Red 5TB drives in Raid 1.

Does anyone have experiences with either box or make recommendations? Thanks in advance!
