Consumer Enclosures
In the consumer market, commonly used configurations of drive enclosures utilize magnetic hard drives or optical disc drives inside USB, FireWire, or Serial ATA enclosures. External 3.5-in floppy drives are also fairly common, following a trend to not integrate floppy drives into compact and laptop computers. Pre-built external drives are available through all major manufacturers of hard drives, as well as several third-parties.
These may also be referred to as a caddy – a sheath, typically plastic or metallic, within which a hard disk drive can be placed and connected with the same type of adapters as a conventional motherboard and power supply would use. The exterior of the caddy typically has two female sockets, used for data transfer and power.
Variants of caddy:
- some larger caddies can support several devices at once and can feature either separate outputs to connect each device to a different computer, or a single output to connect both over the same data cable
- certain caddes don't require a power supply, instead depending for power on the computer to which they are connected
- some caddies have integrated fans with which to keep the drives within at a cool temperature
- caddies for all major standards exist, supporting for example ATA, SCSI and S-ATA drives and USB, SCSI and FireWire outputs
Advantages:
- relatively high transfer speed; typically faster than other common portable media such as CDs, DVDs and USB flash drives, slower than drives connected using solely ATA, SCSI and S-ATA connectors
- storage; typically larger than CDs, DVDs and USB flash drives
- price-to-storage ratio; typically better than CDs, DVDs and USB flash drives
Disadvantages:
- power; most variants require a supply, unlike CDs, DVDs and USB flash drives...
- size; typically larger than CDs, DVDs and USB flash drives

Famous quotes containing the word consumer:
“Vice is its own reward. It is virtue which, if it is to be marketed with consumer appeal, must carry Green Shield stamps.”
—Quentin Crisp (b. 1908)
