Features
Fast Data Transfer
■ 10 MBytes/second synchronous Fast SCSI data rate
■ 5 MBytes/second synchronous SCSI data rate
■ 3 MBytes/second data rate on the ISA bus, the highest speed
allowed in the Programmed I/O (PIO) environment)
■ 2 MBytes/second asynchronous SCSI data rate
Superior Price/Performance Value
■ High speed PIO data transfer
■ Optional high speed DMA data transfer (supported under
OS/2 on EISA-bus computers)
