  1. I believe that the numbers describe the DVD drive's Read/Write speeds.

    The "SATA" also states what computer bus interface it uses to connect to mass storage devices, instead of IEEE, PATA, SAS, SCSI or USB. -Don't quote me on that xD

    Also, the DVD drive is just a form of Optical Disc Drive that can accept both CDs and DVDs. Blu-ray is another type of Optical Disc Drive.

    Sorry for not being a whole deal of help!
  2. Thats the drive speed (read/write). 1x means 11.08 Mbit/s (1.39 MB/s), 18x and 24x means 18/24 times faster as 1x. 18x = 199.44 Mbit/s (24.93 MB/s) and 24x = 265.92 Mbit/s (33.24 MB/s).
    They are theoretical speeds, doesn't mean that always will work at those speeds.
    In order to write, you should see which is the disc speed.
