(The core may have more direct access to relatively small amounts of memory (cache or registers), but that's a different issue.) The CPU also communicates with peripherals via buses. WebAug 9, 2024 · Hard Disk Drive Physical Description. A hard drive is usually the size of a paperback book, but much heavier. The sides of the hard drive have pre-drilled, threaded holes for easy mounting in the 3.5-inch drive bay in the computer case. Mounting is also possible in a smaller 2.5-inch drive and larger 5.25-inch drive bay with an adapter.

Hard disk drives are accessed over one of a number of bus types, including parallel ATA (PATA, also called IDE or EIDE; described before the introduction of SATA as ATA), Serial ATA (SATA), SCSI, Serial Attached SCSI (SAS), and Fibre Channel. Bridge circuitry is sometimes used to connect hard disk drives to buses with which they cannot communicate natively, such as IEEE 1394, USB, SCSI, NVMe and Thunderbolt.
