1.5: Storage Devices

In this type of RAID, file blocks are split across 2+ drives, data can be written quickly, no redundancy:

0

In this type of RAID, file blocks are duplicated across 2 or more drives, an identical copy of the data is on each drive, required disk space is doubled, high redundancy:

1

In this type of RAID, the speed of striping and the redundancy of mirroring is combined into one, and you need at lead 4 drives:

10

Single layer Blu-ray disc capacity:

25 GB

DVD-ROM (single sided) capacity:

4.7 GB

In this type of RAID, file blocks are striped, a parity block is introduced, requires at least 3 disks, files aren't duplicated but space is used for parity, high redundancy:

5

HDD RPM range:

5,400-10,000 RPM

Dual layer Blu-ray disc capacity:

50 GB

CD-ROM capacity:

700 MB

DVD-ROM (dual sided) capacity:

8.5 GB

BR-R stands for:

Blu-ray recordable

BD-RE stands for:

Blu-ray recordable and erasable

Types of optical media that can written to:

CD-RW, DVD-R/RW, DVD-R DL, BD-R, BD-RE

DVD-R/RW stands for:

DVD read and rewrite

DVD-R DL stands for:

DVD readable dual layer

DVD stands for:

Digital Versatile Disc

Which type of ROM is USB considered?

RAID stands for:

Redundant Array of Independent Disks

This type of storage doesn't have any moving parts:

SSD

SD stands for

Secure Digital

SSD stands for:

Solid State Drive

3 types of hot swappable drives:

USB, Firewire, SATA/eSATA

RAID 10 is used for:

a stripe of mirrors, combines 1 and 0

Name for the piece that reads data off of a spinning platter like a record:

arm and actuator

What is required to write to optical media (discs)?

burner

CD-ROM stands for:

compact disc-read-only memory

CD-RW stands for:

compact disc-rewritable

CD stands for:

compact disk

Non-volatile memory means:

data is not lost when power is lost

eSATA stands for:

external SATA

This type of storage uses moving parts and spinning magnetic disks:

hard drive

__________-based RAID is a feature of the hard drive controller, is configured outside of the OS, uses high performance, is usually invisible to the OS, and is used more for speeds:

hardware

Name for storage that can be removed while the system is still powered on:

hot swappable

This type of storage uses both spinning platters and SSD:

hybrid

LTO stands for:

linear tape-open

RAID 1 is used for:

mirroring

Name for spinning magnetic disk within hard drive:

platter

_________-based RAID is a feature of the OS, doesn't require special hardware, has lower performance

software

RAID 0 is used for:

striping

RAID 5 is used for:

striping with parity

This type of drive is used to archive data over a long period of time at a low cost:

tape drive
