RAID stands for

• Redundancy In Array of Disk
• Redundant Array of Independent Disks.
• Redundant Area Inexpensive Disk
• Real Array Inexpensive Disk

RAID 0

• Mirror
• Striping
• Spanning
• Duplexing

RAID 1

• Mirror
• Striping
• Spanning
• Disk Duplexing

RAID 5

• Mirror with parity
• Striping with parity
• Spanning with parity
• None of the above

A thick magnetic disk that consists of several aluminum platters, each of which requires a read/write head for each side.

• SSD (Solid State Drive)

• CPU (Central Processing Unit)

• HDD (Hard Disk Drive)

• DHD (Disk Hard Drive)

Flash device with a storage capacity similar to a small hard drive. Used for storing the OS, application, and data files.

• HDD (Hard Disk Drive)

• RAM (Random Access Memory)

• CD/DVD (Compact Disc/Digital Video Disc)

• SSD (Solid State Drive)

Storage medium that uses lasers for both reading and writing information.

• Integrated Drive Electronics

• Solid State Drive (SSD)

The original SATA standard. Provided 1.5 Gbps data transfer.

• SATA 0

• SATA II

• SATA 5

• SATA 1

Combines disk striping across multiple disks with parity for data redundancy. Parity information is stored on each disk.

• RAID 0 (Striping)

• RAID 1 (Mirroring)

• RAID 5 (Striping with Distributed Parity)
