Fastest Way to Transfer Files (HDD vs Flash via USB, PCI, etc.)
I was a little surprised when a one gig media file took 40 minutes to copy from my laptop hard drive to the SD card reader built in to my HP Pavilion dv2120us. My expectation was that solid state would be a very quick transfer, with the HDD on the laptop being the limiting factor (and maybe that was the case.) I want to quickly copy content from PCs onto portable devices. What is the best way to do this? A portable media device with a USB connected to a PC with a 10,000 RPM hard drive? What is the specs I should look at to build a fast machine? Is HDD RPM the bottleneck? Is SATA a bottleneck? Is the cardbus the bottleneck, is the SD a bottleneck? Obviously, as you can guess, paying for a 10,000 RPM HDD would be a waste of money if it's not a bottleneck when copying files to an external device. As such, where are the likely bottlenecks? Even the memory of the SD is suspect, as I know on my camera, I have special high-speed compact flash cards--so I suppose the ns speed of the memory is an issue too?
imho, the fastest is eSata; but of course, all pc's must have it.

i agree eSATA is the fastest..
however even a good usb2 sATA or IDE externaly enclousere would work quite well.
I have a icybox with a 400gig IDE drive in it connected through USB2 and it can trasphere data at a sustained rate of 25mb/sec..
not amasling fast but thats going to give you about 1gig transphere a min. (even not running at full speed)
whish is a lot quicker and much more storage.. it does need external power though..
you can buy 2.5 inch (laptop hardrives) enclouses that are much smaller and run of the usb power. these can be about 60+ gig in size and although a bit slower they are much more mobile and than a large hard drive and much faster than a SSD card. they also fit in your pocket..
if i have a bit of cash at the moment i would be getting one.. there not that expensive though..

i object - i mentioned sata as the fastest first !!!
so although access times are in the nano seconds!!! and small transpheres are also very quick (12+mb sec) large continus wites which access multiple cells (SSD stored data in cells on a memory chip) actauly casue it to slwo down.. thsi si why SSD hard drives have yet to really take off. although they are getting better..
look at your SD card and see what speed it is. and then check the speed stated against a chart... i forget exactly but IIRC 80X is about 10mbytes/sec
