The following comments relate to this news article:
article published on 10 August, 2009
Toshiba claims that it will be the first tech company to ship 64GB Secure Digital eXtended Capacity (SDXC) memory cards. The company projects that it will begin shipping the new flash memory cards that utilize the exFAT (FAT 64) file system by Spring 2010.
When announced in January earlier this year, it was revealed that the capacity limit would be around 2 terabytes (TB) of data, but ... [ read the full article ]

Whats the fastest write speed for USB? And don't say 400mbs :P
I suppose this will replace SDHC?
Will we see more flash esata devices? Would a adapter type device require extra power from the USB port?
Or will USB 3 basically take over in the coming years?

First of all, this article needs to be corrected. Obviously the writer was in a negative frame of mind by saying the 64Gb capacity falls short of the proposed 2TB size previously promised. What the author of this article fails to say is that the 2TB capacity wasn't predicted for FIVE MORE YEARS!!! In fact, that announcement even said that there will be incremental sizes in the meantime, until the 2TB size is reached. Seems like 64GB is rigtht in line with what was promised. In addition, it was predicted that the 64GB SDXC wouldn't be announced until late 2009. However, it's only mid 2009, so infact, the tech companies are actually AHEAD of their projections! I suggest the author of this article ( James "Dela" Delahunty) reads his own previous post: http://www.afterdawn.com/news/archive/16573.cfm POOR JOURNALISM, JAMES!
Secondly, I'm saddened that such a shady company as Toshiba, which produces second rate products with minimal customer support is leading the way on this. I'll have to wait until a legitimate tech company produces a higher quality SDXC card before I get one!
Because I'm smarter than you. That's why.

1. I don't know, but it's slow as hell to write on flash, as I'm sure you know.
2. Yes.
3. I didn't even know there were flash eSATA... or did I see one somewhere once? Could you rephrase the second part of this question? If you meant would a flash card require more than +5v from USB, NO, I don't think so. If you meant a larger device, like a HDD or SSD, then Yes, I could see an adapter being required, or additional ports being required for power only (no data).
4. My crystal ball says USB 3.0 and eSATA will co-exist for quite some time, but then it will give way to eSATA. Similar to how PS/2 has now FINALLY given way (almost entirely) to USB. To me, this would be ideal since then you would have standardized the components both inside and outside the case.
P.S. I just refreshed my knowledge on USB 3.0, and to tell you the truth, I'll believe it when I see it. It looks like it's going to have problems with backwards compatibility with older connectors. Hopefully this won't kill the standard. From what I read it's going to add 4 extra wires (that's double 2.0) and full-duplexing. I'm dubious.

480 Mbps, which equals roughly 57 MiB/s. With flash though, USB connection speeds are rarely the bottleneck.

yeap, HDD reads the specified file it is then stored in cache (windows does this for reasons that are beyond me)and then it gets passed to the USB.
i can get 22MB/s on my system tops it wont go past that i know its my PATA HDD thats holding me back.

I am unsure if they are the only one but it seems obviously a great idea.
USB also powers devices can sata do that? I mean sure they could invent a new spec and plug call it X sata and it has up to a 12V 2A line in it or something.
USB 3 dose look interesting

its still going to be a couple years before it hits the shelf's.

Could someone explain why my laptop wont read any memory cards over 2gigs?
I have a 4 gig in my camera and have to use the usb port to read it.

It might be the SD card reader can not read SDHC cards.

The plain SD specification only goes as high as 2GB. Cards with higher capacities will use the SDHC specification, which your laptop's card reader probably does not support.
