So today we have another burner in the SW series; capable of writing CD-R media at 40X, rewriting CD-RW media at 12X, and reading standard CD-ROM's at 40X. The SW240 packs 8MB of buffer memory to prevent the occurences of buffer underrun errors along with Justlink/BurnProof. The drive also supports the new (Mt. Rainier) CD-MRW standard. What is CD-MRW you wonder, well it stands for CD Mount Rainier Rewrite and it is a new optical storage media standard that makes CD-RW disks as handy, and as easy to work with as 1.44Mb floppies are.
