Study Notes

Storage Devices and Media

Storage medium is the physical material used to store data, including hard disks, memory cards, USB flash drives, and optical discs.
Cloud storage stores data on servers accessible over the internet.
Storage device is the hardware used to read from and write to the storage medium, such as hard disk drives, memory card readers, and USB ports.
Reading is the process of retrieving data from a storage medium to memory.
Writing is the process of storing data from memory to the storage medium.

Hard Drives

Capacity refers to the amount of data a storage medium can hold.
Hard disk drives (HDDs) use spinning platters with magnetic particles to store data.
Solid state drives (SSDs) use flash memory to store data, offering faster access, transfer rates, and greater durability than HDDs.
Tracks, sectors, and platters are physical components of hard drives that define the storage space.
Head crash occurs when a read/write head physically touches the surface of a platter, causing damage to the drive.
External hard disks are portable storage devices connected to a computer through USB ports or other interfaces.
RAID (Redundant Array of Independent Disks) uses multiple hard drives or SSDs to increase storage capacity and data redundancy.

Portable Flash Memory Storage

Memory cards are removable flash memory storage devices inserted into slots on computers, mobile devices, and card readers.
USB flash drives (thumb drives) plug directly into a USB port on a computer or mobile device.

Optical Discs

Optical discs are flat, round, portable platters that use lasers to read and write data.
CD-ROMs can read data but not write to it.
CD-Rs allow users to write to the disc once, but cannot be erased.
CD-RWs are rewritable optical discs.
DVD-ROMs can read data, but not write or erase.
DVD-Rs and DVD+Rs are recordable DVD formats.
DVD-RWs, DVD+RWs, and DVD+RAMs are rewritable DVD formats.

Enterprise Storage

Enterprise storage focuses on managing massive amounts of data for large organizations, prioritizing reliability, efficiency, and high availability.
RAID is a key component of enterprise storage, ensuring data redundancy and improving reliability.
Network-attached storage (NAS) is a server that provides storage to a network, improving data accessibility for users and devices.
Storage area network (SAN) is a high-speed network dedicated solely to storage, allowing servers to access data quickly.
Tape drives use magnetic tape to store vast amounts of data, typically employed for backups and archival purposes.
