Blue Ray
Blue Ray

Calling this just a Blu-ray recorder is a little unfair. It’s a multimedia beast, and does a lot more than the BD-R label implies. It’s a PVR with a 1TB hard disk on which you can record up to 684 hours of content.

Disc Drives
Disc Drives

While this is not a technically correct term to use, it is still common. For example, some computers have multiple drive letters (e.g,. C, D, and E) representing areas across one or more hard drives. The hard disk drive also goes by the name HDD (its abbreviation), hard drive, hard disk, fixed drive, fixed disk, and fixed disk drive.

DVD-ROM DVD-R DVD+R DVD-RW
DVD-ROM DVD-R DVD+R DVD-RW

Seems kinda weird, but if you can do so, DVD-RW obviously has significant advantages over DVD-R. DVD-RAM was even more flexible, however, since it let you erase and rewrite sections of an existing DVD, something that you cannot do with DVD-RW. Moving to the plus side is where things get a bit confusing, because DVD+RW came before DVD+R.

Floppy Disk Drive
Floppy Disk Drive

A floppy disk drive (FDD), or floppy drive, is a hardware device that reads data storage information. It was invented in 1967 by a team at IBM and was one of the first types of hardware storage that could read/write a portable device. FDDs are used for reading and writing on removable floppy discs.

LS120 Drive aka SuperDisk
LS120 Drive aka SuperDisk

NOTE: Unlike a standard floppy disk drive, the SuperDisk drive is an ATAPI device like a hard drive, and as such it is subject to different drive ordering than a floppy drive. Some software may require that the SuperDisk drive be recognized as drive A:\, in order to create a diskette.

Parallel Advanced Technology Attachment (PATA)
Parallel Advanced Technology Attachment (PATA)

Parallel ATA (Parallel Advanced Technology Attachment or PATA) is a standard for connecting hard drives into computer systems. As its name implies, PATA is based on parallel signaling technology, unlike serial ATA (SATA) devices that use serial signaling technology.

RAM Disk

Removable Drives
Removable Drives

Removable disk drives combine the best aspects of hard and floppy disks. They are nearly as capacious and fast as hard disks and have the portability of floppy disks. Their biggest drawback is that they're relatively expensive.

Solid State Drives (SSD)
Solid State Drives (SSD)

In a dual-drive system, the manufacturer will install a small SSD primary drive (C:) for the operating system and apps, and add a larger spinning hard drive (D: or E:) for storing files. This works well in theory; in practice, manufacturers can go too small on the SSD.
