Final answer:
SATA revision 1.0 is characterized by a 1.5 Gaps data transfer rate and a maximum cable length of 1 meter, making it an improvement over older PATA technology.
Step-by-step explanation:
The characteristic features of SATA revision 1.0 include a 1.5 Gbps data transfer rate and a maximum cable length of 1 meter. It is the first version of the SATA interface standards which was introduced to improve on the older PATA technology by providing faster data transfer rates and more efficient cabling. The 1.5 Gaps speed is sometimes referred to as SATA I or SATA 1.5Gb/s, and the 1-meter max cable length was designed to ensure data integrity over physical connections.
