Data

What is a common use case where SSDs are preferred over HDDs?

SSDs are preferred for operating systems, applications, and gaming, where fast load times and quick access to data are important.

What is an advantage of Solid State Storage over Magnetic Storage VC?

Solid state storage have no moving parts compared to the write head that hovers 100 atoms above splitting platter in Magnetic Storage. Therefore it is not damaged by dust or easily damaged.

Why are SSDs faster than HDDs for random access?

Why are SSDs faster than HDDs for random access?

What is the role of the controller in an SSD?

The SSD controller acts like the drive’s brain, handling where data is stored.

How does an SSD store data?

An SSD stores data in flash memory cells that hold electrons representing bits (0s and 1s). The controller manages how data is written, read, and erased from these cells.

What is an SSD (Solid State Drive)?

An SSD is a storage device that uses flash memory (no moving parts) to store data.

What cost advantage does magnetic storage have compared to SSDs?

Lower cost per gigabyte compared to SSDs and other storage types

Name one advantage of magnetic storage related to media.

It is ideal for storing media libraries, games, backups, and large files

What component detects magnetised regions and converts them into binary?

The head of the hard disk drive

In magnetic storage, what does the opposite direction of magnetisation represent in binary?

0

In magnetic storage, what does one direction of magnetisation represent in binary?

1

What component in a hard disk drive changes the magnetisation of the platter?

The write head

How is data stored on a hard disk drive in magnetic storage?

By magnetising tiny regions on spinning metal platters

What happens to the reflected light when the laser moves from a land to a pit?

The reflection changes, which the sensor detects as a different bit value

How does making pits and lands smaller affect storage capacity?

Smaller pits and lands allow more bits to fit on the disc, increasing storage capacity
