Once use of floppy disks started declining, Apple reused the trademark to refer to the (originally Pioneer-built) DVD writers built into its Macintosh models, which can read and write both DVDs and CDs but not mini-discs. As of December 2006, SuperDrives are combination DVD±R/±RW and CD-R/RW writer drives offering speeds of 8x-24x and supporting the DVD±R, DVD+R DL, DVD-R DL, DVD±RW, DVD-9, CD-R, and CD-RW formats along with all normal read-only media. All new Apple computers (except for the MacBook Air) contain the SuperDrive. DVD-RAM support, notably, is absent or unofficial (some OEM drive models). The recent server version of the Mac Mini optionally includes an external USB SuperDrive, since a SATA hard drive now occupies the space formerly held by the optical drive.
