Is it just me, or does the thought of a 20Mbps transfer rate seem extremely slow?

That is a little on the slow side

Just think of it... in a few years, this technology will either fix that error, or become obsolute.

USB2 can't pull 40MB, no matter what techies say. 50kb is more like it. So 20MB (truth) is great!


At least farting ferrets are better than stinky stoats.

USB 2 does about 480 mbps, which is roughly 60 mb per second. So yeah, 20 mega-bits per second (compared to USB2's 480) is very slow in comparison I wonder whether they've released the info wrong, and meant to say 20mb/s instead of 20mbps

Nex, that's 20Mbps which turns out to be about 2.5 megabytes per second. And that is quite slow.

If you read the official press release

http://www.inphase-technologies.com/news/500gigabit.html

it actually does specify Megabytes.

Boo!

It is still faster than HDD and USB2 though.

No, its not. USB2 can handle about 60 mb per second (not megabits) and this can handle 20 mb per second. So its not faster.


@spooky; Phew. I was very worried for a while. A storage medium that can trasnefr data at 20mbps How useless would that be...

It can't, ok!?
It can THEORETICALLY transfer that much, but I have several USB memory sticks other things, and none of them break 50KB/S. They are locked there.

Nex, are using USB 1 or 2?


Thanks for the clarification Spooky, so that article has a typo. And I thought my network could transfer 5x faster than it could read.

USB2. I am using a 500ma port, USB2 compatible with a USB2 device. Hell, a lot is probably lost in powering these devices, but that is no excuse. Is it 40MB/S shared between all devices?
(looks at USB mouse, keyboard, b/tooth dongle, PDA and other worthless junk)

You must not have the proper drivers. I've transferred 300mb files in about 5 seconds (or so) to my MP3 player.

20MBps is a bit slow, but when you compare it to the current backup technology (tape drives... *shudder*) it ain't so bad. Besides, that's for the first editions with 300GB only. They should start speeding up later.

DC emulator code size: 9MB. Compiled: 4MB.
