Well, an A3 (or US tabloid, 11x17) image in 16-bit-per-channel colour,
at 2400dpi, is of the order of 6 gigabytes of data uncompressed.
And yes, I do have an Epson scanner that can do that, although I
usually use 8-bit-per-channel since GIMP doesn't handle 16-bits
(16bit R, 16-bit G, 16-bit B) very well yet.
So you can have quite a bit of bandwidth.
And on a USB connection it can take quite a while to transfer
