HDD and SSD drives are used for permanent storage of data on computers and laptops. But what are the differences between the two, and what are their advantages?
The main reason for the prevalence of hard disc drives (HDD) is their low cost, large storage capacity, and relatively fast data writing.
Each disk contains a metal or glass plate with a thin layer of magnetic material on top. The plates are rotated, most commonly at a speed of 7200 turns per minute (for server and high-performance models up to 10 or 15,000 rpm, for some low energy and 2.5" laptop discs only 5400 rpm). They are rigid in design - hence the name "hard" drive. Conventional 3.5" drives for desktop PCs feature 4 plates and 8 read heads (one head on each side of the plate).
SSD (Solid State Drive) drives are purely electronic - they store data in flash memory NAND - and do not work with any moving parts. As a result, they have a shorter reaction time but are less prone to mechanical damage. They are used mainly in laptops.
