The newest and best kind of drives for DTV. New technology makes these drives better then AV optimized.
A term used to describe a 8-bit wide bus operating Ultra (between 10 MHz and 20 MHz). The maximum data rate of a Ultra SCSI device or bus is 20 Mbytes/sec. Sometimes referred to as Fast-20.
A standard for SCSI data transfers. It allows a transfer rate of up to 20 MBytes/sec over an 8-bit SCSI bus, and up to 40 MBytes/sec over a 16-bit SCSI bus. The STA (SCSI Trade Association) supports using the term "Ultra SCSI" over the older term "Fast-20."
Provides 20 MB/s transfers over an 8-bit bus or 40 MB/s transfers over a 16-bit Wide SCSI bus. Also known as Fast-20 SCSI, this feature is most commonly found in SCSI-3 drives.
(8-bit Narrow) 20 MB/s 50-pin High Density (mini 50, micro 50) Used for peripherals like CD-R and Iomega Jaz drives
Ultrasonic Ultra Wide SCSI
This is SCSI that communicates twice as fast as standard SCSI-2. Normal Ultra-SCSI transfers data at 20MBps, and Wide Ultra-SCSI transfers data at 40MBps....
Ultra SCSI is an evolution of the standard SCSI interface. Sometimes referred to as Fast 20, Ultra SCSI enables external transfer rates of up to 20 Mbytes per second on an 8-bit bus and up to 40 Mbytes per second on a 16-bit bus. Ultra SCSI uses the same physical connections as SCSI-2 and is fully backward compatible. To reach the maximum transfer rates of up to 20 (8-bit) or up to 40 (16-bit) Mbytes per second, the controller and disc drive both must be Ultra SCSI devices. Ultra SCSI also reduces total cable lengths to half of the Fast SCSI-2 specification. Ultra SCSI represents the parallel SCSI solution defined in the SCSI-3 ANSI standard specification.
Uses an 8-bit bus, and supports data rates of 20 MB/sec. An extension of SCSI 2 proposed by a group of manufacturers which doubles the transfer speed of Fast-SCSI to give 20MB/sec. on an 8-bit connection and 40MB/sec. on a 16-bit connection
SCSI protocol that has a bus speed of 20 MB/s in the normal SCSI configuration and 40 MB in the Wide SCSI configuration.
