Which is best for Raspbian, 'udev' or 'mdev'?

Question

I'm trying to detect when a mass storage USB device been inserted to my Pi. If it's a USB mass storage device(a pendrive), I want to transfer files from Pi to the pendrive and unmount automatically once the transfer is complete. (Right now I'm using my Pi for TimeLapse only)

When searching, some says mdev would serve for embedded purpose and is much more easier and also uses less memory than udev.

Which one would be the best? Has anyone have used mdev on your Pi so far?

I'm running Raspbian, and my hardware is B.

Answer 1

When searching, some says mdev would serve for embedded purpose

A raspberry pi all by itself is not, in fact, a truly embedded device, although it is akin to one and might be used to create or develop such things, which is why there is this association. But it is really a general purpose computer like a PC.

Many embedded contexts involve systems which are much, much more limited than the pi; 512 MB of memory is easily several orders of magnitude greater than such systems.

Raspbian comes equiped with udev and that's what you should stick with.
