Detailed explanation-1: -Which of the following platter spin rates is not commonly associated with conventional magnetic hard disk drives? D. 12, 000 rpm HDDs were once produced in low quantities but were never common.
Detailed explanation-2: -A solid state drive is non-volatile memory (NVM) computer hardware that stores data without moving parts. Whereas hard disk drives (HDD) use a spinning magnetic disk and a mechanical write head to manipulate data, SSDs use charge in semiconductors.
Detailed explanation-3: -A typical HDD design consists of a spindle that holds flat circular disks, called platters, which hold the recorded data. The platters are made from a non-magnetic material, usually aluminum alloy, glass, or ceramic.
Detailed explanation-4: -Hard disks, zip disks and floppy disks are common examples of magnetic disks.
