Which of the following is a volatile form of memory, requires power to retain data, and is included in an SSD to increase its read/write performance?           

• Controller

• Host interface

• DRAM

• NAND flash memory

The concentric circles on platters where all the information on a hard disk resides are referred to as ________.   

• Disk interfaces

• Tracks

• Rolling headers

• Cylinders

Identify the correct statement:    

• Each platter in an HDD has a varying track density.

• Track density plays no role in determining the storage capacity of a hard disk.

• The lesser the track density of a hard disk, the more information can be stored on it.

• The greater the track density of a hard disk, the more information can be stored on it.

Which of the following statements is true?  

• The read/write performance of an HDD is directly proportional to the RPMs (revolutions per minute) of the drive platter

• The read/write performance of an HDD depends on the actuator

• The read/write performance of an HDD is directly proportional to the number of jumper pins available on the HDD

• The read/write performance of an HDD is indirectly proportional to the RPMs (revolutions per minute) of the drive platter

Which of the following regions on platters store data?

• Tracks

• Rolling Head

• Controller

• SCSI

Which of these is the smallest physical storage unit on a disk platter?

• Track

• Sector

• Cylinder

• Disk Interface

Which of the following is a high-speed serial expansion card integrating flash directly into the motherboard and is connected to the host machine through its own serial link by eliminating the need to share a bus, reducing latency, and enhancing the data transfer speeds between a server and storage?

• ATA/PATA (IDE/EIDE)

• Parallel ATA

• Serial ATA

• PCIe SSD

Which of the following is a technique that is used to assign addresses to physical blocks of data on hard disk drives?
