USB3 for backup..........what a difference!

[admirable]

Just transfered a folder with 31GB data (various images) to a portable hard drive in 16 mins, the same folder on the same drive but via usb2 is 27 mins.

Just you wait for Thunderbolt then

Should take you about 2 min

My transferring of files from usb/sd cards has slowed down for some unknown reason. Strange....

USB2.0 = 480 Mbit/s

USB3.0 = 4.8Gbps

It also depends on the media which is being written from and to, there is no point having a Lightpeak ((Thunderbolt) 10Gbps) connection if you only have a hard drive which will only read or write @ 50MB/s

I got a USB3 card reader for my desktop, very easy to install (5 mins) and works a dream. 16GB SDHC card cleared in under 4 mins. Just ordered a 7D and a couple of 16GB compact flash, hope it'll be as quick with them.

Stupid question: will a usb3 external hard drive work ok with a laptop that only has a usb2 port?

 

[admirable]

yes

The usb3 hard drive will work on usb2 but will of course run at the slower usb2 speed. Thank goodness for backwards compatibility!
