| Removable storage in the video environment falls into two categories. One is cartridge-type systems such as the Iomega Jazz drive. The other category is "hot swappable" hard drives which can be transported or stored. |

| Cartridge type systems are the most convenient way to store large amounts of data. The cartridges can be easily removed, replaced, stored, or transported, and many other users may have the same type of cartridge drive. At up to 2 gigabytes, they can each store around 15 minutes of highly compressed video. |

| Cartridge-type drives are too slow for any but the most highly compressed video to play directly off of them. And although 2 gigabytes may seem like plenty for people working with still images, it is not much if you're using uncompressed video. In fact, it will only store a few seconds at the highest data rates. Combined with the fact that they will not flow data at the required rates, they have little use for high-end video storage. |

| With removable hard drives, you are using the exact same high data rate hard drives as you would use with fixed installation. However the drives are installed into removable "caddies," which plug into receptacles installed in the drive bays and connect to the SCSI or ATA bus. When the drive/caddy unit is pulled out, it can be stored or transported as easily as a cartridge. When using a stripe set, all the drives must be removed together and replaced in the same physical order used for recording. |
