Good job, zevia!!
You are getting some great data flow rates.
I am showing a burst rate of about 12-MB/s on my 712’s USB interface, and showing a read rate of 9X in nero (rip-lock off). Sucks.
On my Samsung SD-816B, I show a burst rate of 14MB/s on its interface, and a read rate of 11X. OK.
On my external HDD, a 7200 RPM/ 120GB, I’m showing 15-MB/s burst and read, which is (today’s) data transfer rate, also.
After some tweaking, some months back, I was able to hit 18-MB/s (or was it 22?) on that ext. HDD, but, alas, it has apparently gone to shit, again.
Tomarrow, oh course, my mileage may vary
I guess one could research the fastest USB enclosure chipset, but I’ll just wait for firewire 2 (which is the best excuse I can think of right now ).
As you saw in my first post, I run allot of USB devices from my notebook.
XP decides which ones get what percentage of the USB resources. I actually saw that in a utility, somewhere, as far as what devices were taking what percentage… eventhough they were not currently in use (I think I was trying to speed benchmark my SD cards at the time). It does not do this consistently, though… it’s very strange and annoying.
I would be willing to bet, though, that if I were to un-install all my USB devices and controllers, including the PC card USB, and then reinstall only the ext. 712a on one of the factory ports, it would scream with speed.
But I know that it wouldn’t last, and THAT knowledge is what drove the point that I was attempting to make. As soon as I go back to my “working, real world, configuration,” USB T/R goes back in the crapper. Besides, who wants to unplug all their peripheral devices, and reboot, so they can get a 12X or, MAYBE, 16X burn? Not much of a time saver there.
I usually burn at 4X or 6X just to avoid it.
On a desktop, on its own PCI / USB card, it might be a whole different deal, though. Its speed might stay there day in / day out??
But, anyway, again good job on your testing and thank you… you appear to be somebody who can get a little obsessed with interesting things… just like me
BTW: 53-running services!! Good god, I thought I was bad at 37.
