What is a key advantage of solid-state drives (SSD) over mechanical mass storage devices?

• Higher data transfer rates

• Higher data storage capacity

• More affordable prices

• Longer lifespan

Answer explanation

Solid-state drives (SSD) have a key advantage of higher data transfer rates compared to mechanical mass storage devices, making them faster in accessing and transferring data.

Which of the following is NOT a factor to consider when evaluating the performance of storage devices?

• Type of data transfer

• Color of the device

• Read and write performance

• Data throughput

Answer explanation

The color of the device is not a factor to consider when evaluating the performance of storage devices. Factors like type of data transfer, read and write performance, and data throughput are more relevant.

According to the text, what does reliability in storage devices concern?

• Color and size of the device

• Risk of data corruption and device failure

• Speed of connectivity

• Brand of the device

Answer explanation

According to the text, reliability in storage devices concerns the risk of data corruption and device failure.

Which companies are mentioned as mass storage device vendors in the text?

• Apple, Google, Microsoft

• Seagate, Western Digital, Hitachi

• Intel, AMD, Nvidia

• Samsung, Toshiba, Fujitsu

Answer explanation

The correct companies mentioned as mass storage device vendors in the text are Seagate, Western Digital, and Hitachi.

What is the main disadvantage of using a SATA port for SSD connections as mentioned in the text?

• It supports a maximum transfer rate of up to 6.7 GB/s.

• It does not support NAND flash memory.

• It is only compatible with 2.5-inch SSDs.

• It has a maximum transfer rate of 600 MBps.

Answer explanation

The main disadvantage of using a SATA port for SSD connections is that it has a maximum transfer rate of 600 MBps, which is slower compared to other interfaces.

Which type of NAND flash memory is described as more reliable and more expensive in the text?

• Single-level cell (SLC)

• Multi-level cell (MLC)

• Triple-level cell (TLC)

• Double-level cell (DLC)

Answer explanation

Single-level cell (SLC) NAND flash memory is described as more reliable and more expensive in the text

According to the text, for what reason might SSDs perform worse than HDDs?

• When they are older than 5 years.

• When serving multi-gigabyte file sizes.

• When installed in a desktop PC.

• When used with a SATA port.

Answer explanation

SSDs might perform worse than HDDs when serving multi-gigabyte file sizes due to their architecture and limitations in handling large continuous data transfers.

What interface is mentioned as being used by modern SSDs to communicate with the host, bypassing older interfaces like SATA?

• PCI Express (PCIe)

• Universal Serial Bus (USB)

• Integrated Drive Electronics (IDE)

• Network Attached Storage (NAS)

Answer explanation

Modern SSDs use PCI Express (PCIe) interface to communicate with the host, bypassing older interfaces like SATA.

What form factor is mentioned for NVMe SSDs that is considerably smaller than a PCIe adapter?

• M.2

• mSATA

• 2.5-inch

• 3.5-inch

Answer explanation

The correct form factor mentioned for NVMe SSDs that is considerably smaller than a PCIe adapter is M.2.

What is the primary storage medium in a hard disk drive (HDD)?

• Magnetic tape

• Solid-state drive

• Optical disc

• Metal or glass platters

Answer explanation

The primary storage medium in a hard disk drive (HDD) is metal or glass platters, where data is stored magnetically.
