Study Notes

Storage Devices

Data drives provide non-volatile storage of data, designed to permanently store user data, user applications, and the Operating System.
Data storage devices can be classified according to the media on which the data is stored: Magnetic, Solid state, and Optical.

SSDs

SSDs come in three form factors: Disc drive form factor, Expansion cards, and mSata or M.2 modules.
Non-Volatile Memory Express (NVMe) specification allows SSDs to attach to the PCIe bus without requiring special drivers.
Solid State Hybrid Drives (SSHDs) are a compromise between a magnetic HDD and an SSD, combining a magnetic HDD with onboard flash memory serving as a non-volatile cache.

Optical Storage Devices

Optical drives are removable media storage devices that use lasers to read and write data on optical media.
There are three types of optical drives: Compact Disc (CD), Digital Versatile Disc (DVD), and Blu-ray Disc (BD).
CD, DVD, and BD media can be pre-recorded (read only), recordable (write once), or re-recordable (read and write multiple times).

Magnetic Media Storage

Magnetic media storage represents binary values as magnetized or non-magnetized physical areas of magnetic media.
Common types of magnetic media storage drives include: Hard Disk Drive (HDD), Tape Drive, and Floppy Disk Drive (FDD).
HDDs have drive motors designed to spin magnetic platters and move the drive heads, with speeds measured in revolutions per minute (e.g., 5400rpm, 7200rpm, 10,000rpm).
Tape drives use a magnetic read/write head and removable tape cartridge, with common storage capacities varying between a few GBs to many TBs.

Adapter Cards

Adapter cards increase the functionality of a computer by adding controllers for specific devices or by replacing malfunctioning ports.
Common adapter cards include: Sound adapter, Network Interface Card (NIC), Wireless NIC, Video adapter or display adapter, and Universal Serial Bus (USB) controller card.
Computers have expansion slots on the motherboard to install adapter cards, including Peripheral Component Interconnect (PCI), Mini-PCI, PCI eXtended (PCI-X), PCI Express (PCIe), Riser card, and Accelerated Graphics Port (AGP).
