Physical Storage Flashcards
Disk Drive
A computer component where hardware information, computer operating system software, and application data are stored.
SCSi
A set of standards for physically connecting and transferring data between computers and peripheral devices.
Hybrid Drive
A magnetic hard drive with flash memory chips added to it.
SAS (Serial Attached SCSi)
A technology designed to move data to and from computer storage devices such as hard drives and tape drives.
USB Flash Memory
A solid state memory card enclosed in a case with an integrated USB interface.
Tape Drive
A drive that reads and writes data onto a magnetic tape, which is housed in a protective casing called a cassette or cartridge.
Optical Disk
A disk that is used to store information such as music, movies, software installation programs, photographs, and more.
What is a benefit of solid state drives over magnetic hard drives?
Faster boot and access speed
What is an IP based storage networking standard for linking data storage facilities?
iSCSI
What is an error screen displayed on a Windows computer system after a fatal system error, also known as a system crash?
BSOD
solid-state drives store data on a series of non-volatile flash memory chips.
True
solid-state drives are available in multiple and bigger form factors.
False
solid-state drives don’t suffer mechanical wear during operation and are less susceptible to damage due to shock or magnets.
True
solid-state drives are much slower when it comes to random access of small amounts of data.
False
solid-state drives give much faster boot times and increase system performance.
True
What RAID levels incorporates disk striping?
RAID 10, RAID 5, RAID 0
RAID 1 is a type of RAID for standardizing and categorizing fault-tolerant disk systems by using disk mirroring.
True
RAID 10 combines two RAID levels into one and uses RAID 1 and RAID 0 to provide both mirroring from level 1 and striping from level 0.
True
What does RAID 0 do?
Takes the contents of files and spreads them in roughly even parts across all drives in the RAID array.
What does RAID 10 do?
Requires four hard drives, two hard drives for the disk mirror and then two more disks to strip the mirrored disks.
What does RAID 1 do?
Writes identical data to two or more hard drives
What does RAID 5 do?
Uses disk striping across at least three drives and includes parity data.
What are the steps to replacing a failed RAID drive?
- Create a backup of the data.
- Remove the failed drive.
- Install a new drive of equal or greater capacity in place of the failed drive.
- Verify the new drive which is detected.
- Add the new drive to the RAID array.
- Start the rebuild process.
What type of optical drive can read CDs and DVDs, and record and rerecord DVD optical disks?
DVD-RW
What optical drive technology uses a 405 nm wavelength laser?
Blu-ray
The capacity of a Blu-ray BD-XL quadruple-layer optical disc is 128 GB.
True
What is the capacity of a DVD single-layer, double-sided optical disc?
9.4 GB
What is the capacity of a DVD dual-layer, single-sided optical disc?
8.5GB
What is the capacity of a Blu-ray (pre-BD-XL) optical disc?
25GB per layer
What is the capacity of a Blu-ray BD-XL triple-layer optical disc?
100GB
What is the capacity of a DVD dual-layer, double-sided optical disc?
17GB
What is the capacity of a Blu-ray BD-XL quadruple-layer optical disc?
128GB
A tape drive is a data storage device that reads and writes data on a magnetic tape.
True
CompactFlash (CF) cards are popular in high-end digital single-lens reflex cameras, but are less common in other consumer devices.
True
You can corrupt the data on your flash drive or memory card if you remove it from your computer or device incorrectly. True or False?
True
Secure Digital Card
A solid state memory card developed by the SD Card Association in 1999 and is most popular for consumer electronic device storage
Compact Flash
A solid state memory card standard developed by SanDisk in 1994 and is popular in high-end digital single-lens reflex cameras
What are a set of standards for physically connecting and transferring data between computers and peripheral devices?

BD-R
What solid state memory card is enclosed in a case with an integrated USB interface?
Pen drive
What provides the ability to replace a hard drive and optical drive with a similar component while the computer or device remains in operation?
Hot swapping
What can be used as an interface for input or output devices?
SDIO
