BenchmarkReviews.com: How much is too much? For those who tend to answer "...it's never enough!" there is the QNAP TS-879U-RP Turbo NAS. With eight 3.5" drive bays available, there is a potential for 24TB of storage and transfer rates of more than 10 Gb/s. That's ten times more data than any home PC can pump through its ubiquitous GbE network interface, and twenty times faster than what the latest generation of SSDs can muster. This is for people who have serious data appetites and deep pockets. The cost to fill this unit up with HDDs, in the early days of 2012, is enough to give some people pause; for most business owners, it's a small and necessary cost.
