SSDs

Solid State Drives, which have much faster read/write speeds than traditional drives, no moving parts, lower power consumption, and generate less heat.

Hard Disk Drives (HDDs)

A storage device that uses magnetic media, with spinning platters and moving read/write heads.

eSATA

External SATA, used for external storage that needs internal SATA speeds.

RAID 0

A disk configuration that uses striping to split data across multiple drives for improved speed, but if one drive fails, all data is lost.

BD-R

Blu-ray Disc Recordable, a type of Blu-ray disc that can be written once.

NTFS

New Technology File System, a file system that supports larger file sizes, better security features, and disk quotas compared to FAT32.

Thin Provisioning

A storage allocation method that allows users to see full allocated capacity while only using space as needed.

Defragmentation

The process of consolidating fragmented files on a disk to improve access speeds.

Storage Pools

A collection of physical drives that can be used to create storage spaces.

SATA3

An interface standard that doubles the speed of SATA2 to 6 Gb/s and includes better power management and wake from sleep features.

Flash Devices

Storage devices that use electrical circuits to store data and have no moving parts, unlike hard disks.

Chkdsk Utility

A tool used to detect and mark bad sectors on a disk to prevent their use.

Volume

A logical division of a drive that can span multiple partitions.

Parity

Error-checking information used in RAID configurations to rebuild data if a drive fails.

Cross-linked File

A situation where multiple files point to the same data location, causing data corruption.

SATA

Serial ATA, a standard for connecting hard drives and optical drives to a motherboard.

RAID 5

A configuration that offers improved storage efficiency and can survive one drive failure, requiring a minimum of 3 drives.

Partition

A physical division of a hard drive into separate sections for data management.

Mount Point

An NTFS folder that serves as a link to a volume in storage management.

DVD

Digital Versatile Disc; an optical media format that typically holds between 4.7 GB and 8.5 GB.

Fragmentation

The condition where files are split across the disk, leading to slower access times.

SAS/SATA Drives

Types of hardware drives that can be used to create storage pools.
