Corsair has just launched a 128GB Voyager GT USB flash drive that is sure to be at the top of every road warrior's wish list. Here is a snippet from the press release:

The newest Flash Voyager GT is based upon a revolutionary design that employs a unique dual-controller architecture to achieve SLC-levels of performance using MLC NAND flash memory. The 128GB Flash Voyager GT is able to achieve read speeds of up to 32MB/sec and write speeds of up to 25.6MB/sec, with the limiting factor effectively being the speed of the USB 2.0 bus and operating system overhead.

I think they are full of it.

32MB/s is 184Mbit.
USB 2.0 is 480Mbit.
Even with a 50% USB 2.0 overhead, this drive doesnt come close to saturating it.
 
Have you ever used a 64gb flash drive? You would be lucky to get 1MBp/s write speed on most... They may be full of it, but that's a hell of an improvement.

Thats a bit low.
I just tested my crappy slow 16GB flash voyager.
It copied 659MB in 94 seconds.
Average transfer rate is 8MB/s
 
^^Sorry 759MB copied.
Write speed is still 8MB/s
 
LOOK AT THE SIZE OF THAT THING.

WHY? It's worthless as a thumb drive as it's dimensions will not allow it to work in most scenerios.... And how much does the damn thing weigh?? They should have just classified it as an external hard drive or "external flash device" something, something...
 
If they are indeed limited by USB 2.0... why didn't they make it USB3.0 and backwards compatible with 2.0... Would impress me much more than them saying they maxed out USB 2.0
 
USB 3.0 would probably add some cost and R&D to get done yet, and i doubt it maxes usb 2.0 bus, my usb hard drive can copy easy at 30 MBs,

Maybe they should make the thing eSata that'd be nifty but that'll never come around as Usb 3.0 i though was supposed to address the latency issues so hard drives would perform alot better.

I hope you're being sarcastic.
 
There is some serious BS in this thread

1. I have an external USB drive that at most can manage 33MB sec on the bus I have seen it dip as low as 17MB a second. The same drive on my firewire 400 port says pretty much at 35MB sec The min write speed on the drive in question is 54MB sec and max is around 85MB. This is right in line with Corsair's claim about the USB being the limiting factor.

Check your math. AFAIK noone ever used 5.75bit bytes.

32*8 = 256. USB hardrives are hard pressed to get 40MB/sec despite platters being able to do several times that, so they're not far from maxing the bus out.
 
Shit for only $400 at the Egg. I have to bite.

You crazy, fuck that. I'll spend $400 on...................anything else.
 
Could this be used as a harddrive? Read Write is not that bad, is the access time on "flash drives" the same as SSD (or rather the question is, significantly less then disc drives).

Im not asking if this is a replacement for true SSD, but if you looking for something small, low powered and quite could this work?

EDIT: Meh, nvm, looking at Newegg puts most 128GB flash drives in the $300-$400 range which is more then middle range SSD 120-128GB drives.

Aye, I concede the maths error.
*slaps calc and self for not spotting it*

I'm not convinced that the USB 2.0 bus itself is saturated though.
Its not the whole truth as it still only achieves 53% of max bandwidth which is appalling, especially as they stated that USB 2.0 is the limitation.
There is some cheapskatedness going on here, either that or USB 2.0 isnt really capable of 480Mbit, in which case we have all been swindled either way!
