Storage Flashcards
Due to size restrictions and the compact nature of laptop devices, this type of storage media has become less commonly found on new laptops.
Optical
Examples of mass storage device interfaces include [3]
- SATA
- IDE / PATA
- SCSI
When installing two PATA drives on a single cable, each drive must be configured with a jumper to designate it as either a primary drive (a.k.a. “master”) or a secondary drive (a.k.a. “slave”). The “cable select” jumper setting option automatically configures the drive as master or slave according to its position on a cable… T/F
True

Identifies physical device on a SCSI chain
Which of the following is a way to identify logical partitions on a SCSI hard drive?
LUN
Which of the following are types of storage media that can be read, but not written to? [2]
CD-ROM
DVD-ROM
Which of the following is an example of Write Once, Read Many (WORM) storage media?
BD-R
What are the storage limitations of a standard CD-ROM media format? [2]
- Up to 737 MB of data storage capacity
- Up to 80 minutes of uncompressed audio
Examples of storage media that can be erased and written to multiple times include [3]
- DVD-RW
- BD-RE
- CD-RW
A single-sided, single-layer DVD disc can store up to:
4.7 Gb
A single-sided, double-layer DVD disc can store up to:
8.5 Gb
A standard-size single-layer Blu-ray disc can store up to:
25 Gb
A standard-size dual-layer Blu-ray disc can store up to:
50 Gb
What is the difference between BD-R and BD-RE
- BD-R discs can be written to once
- BD-RE discs can be erased and written to multiple times
A single-layer mini Blu-ray disc can store up to:
7.8 Gb
What is the capacity of a dual-layer mini Blu-ray disc?
15.6 Gb
Which of the following are examples of SSD host interfaces? [3]
- M.2
- PCIe
- SATA
Which of the following is a logical device interface used to access non-volatile memory storage devices attached via a PCIe
NVMe
What is the most common form factor for SSD SATA drives?
2.5
Platters of a magnetic hard drive spin at a rate measured in:
Revolutions per minute
Which of the following is the maximum rpm value available in modern HDDs?
15k rpm
Which of the following is the size of a magnetic drive form factor for desktops?
3,5 inch
A data storage solution that integrates HDD and flash memory into a single device is known as a: [2]
- Hybrid drive
- SSHD
Examples of flash memory card formats include: [5]
- SD
- CompactFlash
- Micro-SD
- Mini-SD
- xD
Which of the following is a proprietary flash memory card format used mainly in older digital cameras?
xD
Which one of the following is a data storage solution that combines multiple disk drive components into a single logical unit to increase volume size, performance, or reliability?
Redundant Array of Independent Disks (RAID)
Which of the following RAID levels does not offer fault tolerance?
RAID 0
Hardware RAID Level 0: [3]
- Is also known as disk striping
- Decreases reliability
- Is suitable for systems where performance has higher priority than fault tolerance
Hardware RAID Level 1: [3]
- Requires at least 2 drives to implement
- Offers improved reliability by creating identical data sets on each drive (failure of one drive does not destroy the array as each drive contains identical copy of the data)
- Is also referred to as disk mirroring
Hardware RAID Level 5: [2]
- Requires at least 3 drives to implement
- Offers increased performance and fault tolerance (single drive failure does not destroy the array and lost data can be re-created by the remaining drives)
Examples of nested RAID levels include: [2]
- RAID 1+0
- RAID 10
Hardware RAID Level 10 requires a minimum of (drives):
4 Drives
Which type of RAID creates a striped set from a series of mirrored drives?
- RAID 1+0
The term “Hot swapping” refers to the ability to replace computer system components without interrupting system operations. T/F
True
Which of the following is an example of a hot-swappable drive? [3]
- USB Drive
- SATA Drive
- eSATA Drive
A Disk Defragmenter is a software tool used to rearrange data on magnetic drives in order to improve system performance. Defragmentation results in faster read/write operations of a magnetic hard drive’s read/write heads because defragmentation consolidates data into the smallest contiguous regions. This means that the heads can access data sequentially without seeking data fragments in different areas of a disk.
T/F
True
An actuator arm assembly failure manifested by loud clicking noise emitted from the inside of the computer case is a problem symptom that should prompt for:
Data backup and hard drive replacement
Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) enables monitoring a system for anticipated:
HDD Failures
