A hard disk drive (HDD), hard disk, hard drive, or fixed disk[a] is an electro-mechanical data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material.
In computing, an expansion card (also called an expansion board, adapter card, peripheral card or accessory card) is a printed circuit board that can be inserted into an electrical connector, or expansion slot (also referred to as a bus slot) on a computer's motherboard (see also backplane) to add functionality to a computer system.
Hardcard is the genericized trademark for a hard disk drive, disk controller, and host adapter on an expansion card for a personal computer. Typically a hard disk drive (HDD) installs into a drive bay; cables connect the drive to a host adapter and power source. If the personal computer lacks an available bus on a compatible host adapter, then ...
A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...
22 mm × 110 mm. A size comparison of an mSATA SSD (left) and an M.2 2242 SSD (right) M.2, pronounced m dot two[1] and formerly known as the Next Generation Form Factor (NGFF), is a specification for internally mounted computer expansion cards and associated connectors. M.2 replaces the Mini SATA (mSATA) standard and the Mini PCIe (mPCIe) standard.
An expansion card in computing is a printed circuit board that can be inserted into an expansion slot of a computer motherboard or backplane to add functionality to a computer system via the expansion bus. Expansion cards can be used to obtain or expand on features not offered by the motherboard.
Bus (computing) In computer architecture, a bus[1] (historically also called data highway[2] or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols.
RAID (/ reɪd /; " redundant array of inexpensive disks " [1] or " redundant array of independent disks " [2]) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
