The data transfer rate is determined by a number of factors...and drive speed is just one aspect of the equation. For example, with two external drives, running at the same speed, same cache, etc., if one is connected via firewire, and the other USB 2.0, the drive connectd via firewire will transfer data faster.
At any rate, ninjaturtle, transfer of data from a SD card is slow enough that I do not think that the rotational spped of your hard drive is going to be very significant.

I just want to add a little to what PeteC2 said.
Most Flash Memory readers, even internal, connects by way of an internal USB header. So not only is the SD transfer, most-likely, going to be slower than even a 4,200 RPM hard drive, but it could be painfully slow if the specific USB header isn't USB2.
If I remember correctly, USB1 is around 12MB, USB2 is like 475MB and the upcoming USB3 is something crazy like 5GB. Those numbers are just approximates... not law! |
