USB2 gives 480Mb/sec so even having to copy twice would still be more than twice as fast as 100Mb/sec network.

I'm only going on recent past experience where I had to copy about 1TB of data on to a new NAS box I got. It doubles up as a USB device and I found copying in USB mode to be far quicker than over LAN.

I don't know exact statistics, but USB2 only manages 480Mb/sec in bursts. The sustained speed is considerably lower.

every USB hard drive ive ever used has been slowwwwwwwwww to say the least often failing totally when you through large amounts of files at them at them @ once I hate them. I did miss the esata bit I do champion that technology and did admit my error. Still the network is already in place and will handle the data transfer with no messing around imo

TouchÃ©. 480Mb max theoretical transfer rate. Its still faster than LAN imho

But as the two computers are already networked and if the transfer rate is genuinely 100Mbps then to transfer 100GB of data using the LAN is just over two hours work.
That's cheap and cheerful, sounds good to me.

I just finished it via filezilla ftp server.
80.5GB in 2 hours

Ok run a test with hardware I have to hand

USB2 2.5 inch hdd

2.9 gig of random sized files

Time to copy to drive and copy from drive 6 minutes 11 seconds add 30 seconds to move device to other computer total approx 6 minutes 40 seconds

Time across network from Vista x64 pc to XP pc of same files was 4 minutes 47 seconds

Take from that what you will

Raistlin · 06-09-2009, 19:01

What network cards are you using zing? What transfer rate are they rated for?

06-09-2009, 19:07

nothing special just the marvel yukon on my asus board and whatever the old am2 board has.

The thing is although the USB drive copied back to the drive @ around 17 /18 MBps it only wrote to the disk @ around 11 . Across the network I got a steady 11 MBps basically meaning it was purely quicker because I didnt have to do it twice.

Ive never liked USB drives and it is only a standard ide 2.5" drive most likely 4200 rpm so a sata would be quicker but I doubt it will be that much faster to actually beat the test although it may. I tried it with a kingston pen drive and copying from that was of but to it was awful ( I didnt expect good results)

The USB speed rate imo is bobbins

Over the 80 gig there would have been about 20 minutes difference

Fair enough, but why bother with an FTP server/client over a Windows network, probably more overheads than Windows built in sharing?
