Hi Bob, Thanks for the info!
I’m not familiar with Launch Media.
We’re on the same page regarding costs. I excluded the price of the drives from my estimate because whether I go with an 8 bay NAS or something like an 8 bay enclosure hanging off a mac mini, the drive cost shouldn’t change. The consideration is that if the QNAP is a better solution, and can be had for just a few hundred more (or the same price), it’s worth considering.
I also think we’re on the same page regarding total performance. I wasn’t suggesting that each user would get/need 1000MB/s, rather that the total array would be capable of ~1000MB/s. Based on what you’ve said, I think hitting 900-1100MB/s is probable, and that works for us.
We’re actually managing pretty well with standard gigabit, so even if the jump to 10GBe doubles our performance, we’d be golden. As you point out, the demands from 4K XAVC are pretty minimal.
