MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -SAS controllers enable the use of SATA drives to expand the storage capacity with cost-effectiveness. The use of SATA hard drives on SAS controllers is made possible by the fact that both share the same infrastructure and have similar features. SATA drives may be plugged into SAS controllers.

Detailed explanation-2: -SATA removes the master-slave relationship between parallel hard drives, with each drive connecting to the motherboard using its own SATA adapter. As well as a specific port, SATA offers substantial improvements in data transfer rates. The original SATA specification transfers data at speeds up to 150 MB/s.

Detailed explanation-3: -SAS is optimal for use in servers and workstations because it has a more versatile array of connectors and is faster at reading and writing data in a continuous computer session. SATA is better for storage purposes because it can write data very quickly, and the hardware is budget-friendly for small businesses.

Detailed explanation-4: -Both SATA and SAS use the same pinout for data and power connections, although the connectors themselves are slightly different. The SATA connection requires two connectors, one for data and one for power. The SAS connection merges power and data into a single edge connected cable.
