    Should be fine - the bottleneck is going to be network speed, not disk performance.

    Well, the HD you'll be reading from the drive is heavily compressed, as it's likely in a distribution format like H.264. So you're only moving 6 - 15mbit/s streams, well below the bitrate of even regular SD video from a DV camcorder (25mbit/s). It's a CPU bottleneck (in decoding) and/or network bottlenecks (in streaming, since for anything above about 3 - 4mbit/s you'd basically need 802.11n or wired Ethernet to guarantee stutter-free playback).

    As a point of interest, UN-compressed HD (of the sort used in broadcast/post-production facilities) can't be read off even 15,000 RPM drives—there's just too much data. :cool:
