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:

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
