How fast is Ultra Wide SCSI and how many bits does it support?

  1. 40 MB/sec and 16 bits

  2. 20 MB/sec and 8 bits

  3. 80 MB/sec and 16 bits

  4. 10 MB/sec and 8 bits

The correct answer is: 40 MB/sec and 16 bits

Ultra Wide SCSI has a transfer rate of 40 MB/sec and supports 16 bits. This is the fastest option out of all the choices, making the other options incorrect. Option B has a slower transfer rate of 20 MB/sec and the same 8 bit support, while option C has a higher transfer rate of 80 MB/sec but still the same 16 bit support. Option D has the slowest transfer rate of 10 MB/sec and the same 8 bit support, thus making them all incorrect. Overall, Ultra Wide SCSI boasts both a high transfer rate and high bit support, making it the most efficient option.
