1. Western Digital defines a megabyte (MB) as 1,000,000 bytes, and a gigabyte (GB) as 1,000,000,000 bytes.
2. Maximum PIO burst rate is specified at 16.6 MB/s using the IORDY signal.
3. Maximum multi-word DMA burst rate is specified using the DMARQ and DMACK signals.
4. Average Read Seek Time is determined by dividing the total time required to seek between all possible ordered pairs of track addresses by the total number of these ordered pairs at nominal environmental conditions.
