Character and method of recording:

Well, the set of accessories is quite scarce. Although it is not a problem to find screws and an IDE cable, I don't think AOpen saved much on them.

Here is what the Nero says you about the drive:

During the tests we found one interesting peculiarity which is typical of many CD-RW drives based on the Ricoh's chipset. The CRW2440 drive didn't want to record discs with ATIP 4M at a speed higher than 12x (although we used the new Mirex media of the maximum write speed of 24x).

The design of the drive is very similar to the 20x model, as well as to the 16x one.

Like with the 20x model, AOpen didn't use the Ricoh's design and made its tray solid, without a door. As usual, it has a headphones jack, a mechanical volume control, one LED and an emergency ejection hole. The drive can be installed both in the vertical and horizontal positions.

On the back there is a special jumper that switches on the UltraDMA 33 mode (the PIO Mode 4 is a default one).

The drive makes quite much noise (or rather whistle) because of air which is constantly drawn through it. Discs ejected after intensive reading are rather warm. The spindown time is not low, that is why if whistle irritates you, you should find a special utility which allows reducing this time.
