I have one of their 1 TB raid storage boxes on my network. It works really well for my purposes , and I think the drives in the box itself are Western Digital.
I dont trust cheap things, normally, They have that brand at MicroCenter, I would not even waste my money they might be c/d drives. When it comes to storring data and footage, only get the best drives A/A+ - I trust G-Technology, and maxotr. But mainly G-Tech.
