Bottom line:

Buyers based in the US may not be familiar with the QNAP name – it's not a familiar name for many outside of Asia. Yet SMB buyers shouldn't let the relatively unknown brand name deter them: the company has put together a powerful NAS line that will give some of the established players a run for their money.

Performance is very good, and ranges toward very high uptime. To be sure, the QNAP doesn’t scale as well as some of the others NAS units on this list. But with a large handful of bays for dedicated caching, this is a top contender for small and mid-range implementations.
