Which drives are we going to look at in this article? Well, the first one is AOpen's 24x burner, codenamed CRW2440. This baby should be able to write a CDR at 24x, a CDRW at 10x and also act as a 40x CDROM drive. It is theoretically quite fast, though not AOpen's current flagship anymore. As we speak(or as I write), they're introducing a new model, capable of burning a CDR at 32x. We'll look at that one, as well as its "older" and cheaper brother, the 16x (called CRW1632). This one writes CDRs at 16x and reads them at 32x. Like the 24x model, it burns CDRW discs at 10x.
