Which version Apple Superdrive do I have?

Hi I recently got a used Apple Superdrive and I am wondering how I can tell if this is the new version Apple USB Superdrive or the former Apple Macbook Air Superdrive? And does anyone know the main difference between the two versions, anyway?

Here is what I have found from my system information:

HL-DT-ST DVDRW GX40N:

Firmware Revision:RQ00

Interconnect:USB

Burn Support:Yes (Apple Shipping Drive)

Cache:1024 KB

Reads DVD:Yes

CD-Write:-R, -RW

DVD-Write:-R, -R DL, -RW, +R, +R DL, +RW

Write Strategies:CD-TAO, CD-SAO, CD-Raw, DVD-DAO

Media:

Type:CD-ROM

Blank:No

Erasable:No

Overwritable:No

Appendable:No

On the bottom of the drive is stampled: "model a1379"

Any help will be appreciated!! Thank you.
