I'm starting to plan a cut-the-cord setup using Tablo and AppleTV. I want to put an external HD on the Tablo (the original two-tuner system), and am thinking of going my usual route for external drives of a WB Red (3TB) inside an OWC box. I have many of these WBRed+OWC drives that I've been using as a Mini-based NAS, and they work fine. I'm just worried that a 5400RPM spinner might not be fast enough for streaming video. Any thoughts on this? I'll be running this all in a wired setup, no wireless links, and will have no more than two TVs on at any given time.
