Iomega REV

Iomega Corporation supplies to the public a series of computer storage devices that utilize proprietary 35-gigabyte hard drive-based removable media. These products are branded "REV". Some REV devices interface via Advanced Technology Attachment Packet Interface, and the rest interface via Universal Serial Bus.

The small removable discs themselves exceed 35 GB/disc and exceed 1.5, 1.1, 0.75 GB/min = 25, 19, and 12 MB/s, when measured inside, on average, and outside. That's up to 166X recording if 1X CD is 150 KB/s; and it's something else in DVD terms. That's faster than some hosts support. For example, people say some third party PCI USB goes no higher than 1.0 GB/min.

Iomega began with ATAPI (SCSI over IDE) and USB, but by summer 2004 had begun selling FireWire and had announced classic SCSI (SPI) and SATAPI (SCSI over SATA) versions of the drive. Iomega (NYSE:IOM) itself was supporting Microsoft Windows and Apple Macintosh, with Linux announced. Support for REV drives in Linux etc. as yet often appears Google-indexed by "RRD", rather than by "REV", because in SCSI the drives actually describe themselves generically as RRD (removable rigid disc), not more specifically invoking the REV brand.
