The drone is subjected to severe wave impacts and constant high-frequency vibration during its weeks-long mission. The onboard computer system must continuously record high-frequency telemetry and sensor data.","difficulty":3,"difficultyBand":null,"totalMarks":2,"sourceTitle":null,"calculatorUse":null,"parts":[{"id":"8dafb444-c3b2-41bb-90ea-c8e2595d6a12","label":null,"content":"State two reasons why a solid-state drive (SSD) is more suitable than a magnetic hard disk drive (HDD) for the data-logging system in this drone.","markscheme":"- SSDs have no moving parts, making them highly shock-resistant and durable against constant vibration and wave impacts. B1\n- SSDs consume less power than HDDs (no motor to spin platters), which helps conserve the autonomous drone's battery life during long-term deployment. B1\n- SSDs have faster write speeds, ensuring rapid logging of high-frequency sensor data without buffering delays or data loss. B1\n- SSDs are lighter and more compact, reducing the payload weight and fitting within the tight physical space constraints of the drone's chassis.

B1\n- The surface of the platter is coated with a magnetic material divided into microscopic domains, where the direction of magnetic polarization represents binary states. B1\n- As these magnetized domains rotate under the read head, their magnetic fields induce a small electrical current (or alter the electrical resistance) in the head. B1\n- The disk controller interprets these electrical changes and converts them into binary data (1s and 0s) for the computer.
