New Terms Hard drive: storage device which uses physical platters to store large amounts of data. The faster the platters spin the faster the drive accesses data Tracks: physical ridges on hard drives which contain information Solid State Drive: Drives that use flash memory to hold and transmit data and thus are more reliable Wear Leveling: system of accessing data that uses multiple memory blocks instead of using a singular memory block continuously. Hard Drive interface: the rules by which a hard drive system operates. These rules regard the number of pins on disks, commands the drive acknowledges, and the number of data bits transmitted at once. Bios: A computer Bios is the setup program that controls the input and output of the computer, including drives. Partitioning: splitting the drive into smaller groups of dives each with its own lettering system.

A hard drive is the most basic form of data storage that uses physical tracks and sectors to separate data and then uses read/write actuators to transmit that data. The faster a hard drive spins the faster it reads/writes data, and thus the more efficient and expensive it is. After the information is read/write off the disk it is transferred by the hard drive interface which controls the way the hard drive works and what cables it uses to transmit data either SATA or sas. SSD’s on the other hand use flash memory to eliminate the moving parts of the hard drives and is generally more reliable but expensive than their hard drive equivalents.
