Detailed explanation-1: -Relies on moving parts. Disk surface can be damaged. Heavy power consumption. Noisy. Slower read and write speed than RAM. 21-Feb-2016
Detailed explanation-2: -Hard drives are usually physically smaller than solid state drives, which means that they have less capacity for backing up data. It is significantly slower to access data stored on a hard drive than on a solid state disk because the hard drive has moving parts, such as the read/write head and the rotating platters.
Detailed explanation-3: -The hard drive contains a spinning platter with a thin magnetic coating. A “head” moves over the platter, writing 0’s and 1’s as tiny areas of magnetic North or South on the platter. To read the data back, the head goes to the same spot, notices the North and South spots flying by, and so deduces the stored 0’s and 1’s.
Detailed explanation-4: -Miscellaneous mechanical failures: parts, particularly moving parts, of any mechanism can break or fail, preventing normal operation, with possible further damage caused by fragments.
Detailed explanation-5: -The simple answer is that SSD has no moving parts and functions similarly to USB memory sticks, while the Mechanical HDD has a magnetic tape and a lot of moving parts. SSD is also considerably smaller and takes up less space in a PC case, in some instances even mounted directly to the motherboard.
