I am trying to quickly download images from a USB digital camera to a hard drive disk attached by USB to my raspberry pi. I want to minimize the time the camera needs to be connected to the pi during the download.
At the moment it seems to copy over to the hard drive at a rate of about 3-5MB/s depending on image size (I use gphoto2 for grabbing the images off the camera), which is OK but a little slow. I wanted to check what the speed was to copy just to the Pi's RAM, at which point I can disconnect the camera and later on move the files from the RAM to the hard drive at leisure.
Could anyone advise how I might be able to copy to RAM? I couldn't find a clear explanation anywhere...
Thanks for your help!
