It's kind of hard for me to get excited about it when . . .
I also have qualms about USB 2.0 transfer rates . . .
. . . is USB 2.0 too slow to transfer that much data real-time
I'd rather stick with a PCI card to assure myself of the datarate issue.
I've been led down this garden path before.
The problem is not so much the transfer rate of the interface spec, but the transfer rate of your computer hardware.
I ran some disk drive throughput tests about six months ago.
Was evaluating external USB drives.
My laptop and older AMD computers were poor performers.
My dual Opteron and new Core2duo machines put the others to shame.
So, for external drives, I'll be moving toward eSATA interface.
That's already been shown to outperform USB 2 in some tests of a friend of mine.
(I'm just getting around to it) -
And why was I even worrying about this problem, you ask?
Well, I'd been badly burned by USB 2 a few years back on an FTA tuner box!
It was eventually running okay for SD, but never quite made it with HD signals.
I blame the two computers I experimented with.
Also, the receiver software was not as sophisticated.
It's matured over the intervening years.
Am I condemning USB tuners?
Well, not necessarily.
But if you mate them to inadequate computers (motherboard chipsets), they may not keep up.
So, user beware. -
