A disk format used by most common platforms, in which the controller electronics reside within the drive housing removing the need for a separate adapter. Other formats include SCSI, IDE, and EIDE.
abbreviation for "Ultra Small Computer System Interface"] A SCSI interface is used to connect a computer to SCSII peripherals (hard drives, removable drives, printers, etc.). UltraSCSI is an updated version of SCSII-2 which can transfer data at 20MBs on an 8-bit connection and 40MBs on a 16-bit connection.
An extension of the SCSI-2 standard that doubles the transfer speed of Fast-SCSI to allow a transfer rate of 20 megabytes per second (Mbps) on an 8-bit connection and 40 megabytes per second (Mbps) on a 16-bit connection.
This is an old term for the FAST-20 data rate. This term was dropped by the ANSI committee because the company UltraStore owned a trademark on the term Ultra SCSI, so it could not be used by the standards committee to describe its work. If you see this term anywhere, read carefully to see if it refers to the UltraStore trademark (which refers to a SCSI FAST class of product) or if the writer is incorrectly using this term for FAST-20.
A high-speed version of the Small Computer System Interface (SCSI) bus. It supports 40-megabyte-per-second transfers.
A method that enables very fast data transfer rates on the SCSI bus. The maximum UltraSCSI data transfer rates are 20 MB/second (40 MB/second for Wide SCSI host adapters).
