Hard disk driveA hard disk drive (HDD), hard disk, hard drive, or fixed disk is an electro-mechanical computer data storage device that stores and retrieves digital data using magnetic storage with one or more rigid rapidly rotating platters coated with magnetic material. The platters are paired with magnetic heads, usually arranged on a moving actuator arm, which read and write data to the platter surfaces.
Solid-state driveA solid-state drive (SSD) is a type of solid-state storage device that uses integrated circuits to store data persistently. It is sometimes called semiconductor storage device, solid-state device, or solid-state disk. Etymologically, "solid-state drive" partly refers to existing data storage devices like tape drives and hard disk drives, which all use a mechanically driven storage medium. SSDs rely on non-volatile memory, typically NAND flash, to store data in memory cells.

He was a co-founder of SanDisk, and its president and CEO from 2011 until its acquisition by Western Digital in 2016. Early life and educationMehrotra was born in 1958 in Kanpur, India. He is the youngest of four siblings. His father was a liaison officer in the cotton industry, who later moved the family to New Delhi when Mehrotra was ten years old.
PC CardPC Card is a technical standard specifying an expansion card interface for laptops and PDAs. The PCMCIA originally introduced the 16-bit ISA-based PCMCIA Card in 1990, but renamed it to PC Card in March 1995 to avoid confusion with the name of the organization. The CardBus PC Card was introduced as a 32-bit version of the original PC Card, based on the PCI specification. CardBus slots are backward compatible, but older slots are not forward compatible with CardBus cards.
Flash memoryElectronic non-volatile computer storage deviceA disassembled USB flash drive in 2005. The chip on the left is flash memory. The Silicon Motioncontroller is on the right.Flash memory is an electronic non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR and NAND logic gates. Both of these use the same cell design, consisting of floating-gate MOSFETs.
Memory cardA memory card is an electronic data storage device used for storing digital information, typically using flash memory. These are commonly used in digital portable electronic devices, such as digital cameras as well as in many early games consoles such as the Neo Geo. They allow adding memory to such devices using a card in a socket instead of protruding USB flash drives.

EEPROMEEPROM or E2PROM (electrically erasable programmable read-only memory) is a type of non-volatile memory. It is used in computers, usually integrated in microcontrollers such as smart cards and remote keyless systems, or as a separate chip device, to store relatively small amounts of data by allowing individual bytes to be erased and reprogrammed. EEPROMs are organized as arrays of floating-gate transistors.
