Close, but it’s actually 40Mbps.
Correcting for initial miscalculation…
(6 streaming devices x 10Mbps) + (4 tuners x 10Mbps) = 100Mbps = ~12.5MBps
USB 2 theoretical maximum thruput is 480Mbps.
Thruput can be half that rate, at around 240Mbps, like when using MS Windows XP, for example.
Some things to note.
There are 2 types of thruput rates the Tablo utilizes.
One is for storing data on the hard drive, and the other is for streaming across a network.
They might not be the same rates.
For example, the Tablo may very well be writing to its hard disk at a steady rate of 10Mbps, during a recording, however, it doesn’t seem to stream at a stead 10Mbps across the network when viewing the same recording.
Looks like it bursts the stream, waits a few seconds, and continues the next burst.
That being said, the rates set in the Tablo settings for ‘Live TV Quality’, and ‘Recording Quality’ must be the lowest common denominator between hard drive, and network thruput.
The hard drive needs to have a thruput that is equal to, or greater than the network thruput, which should not be a real world issue, but it’s interesting to think about.
