SSD vs HDD

A person with a little knowledge of computers and technical background always come across to the dilemma regarding what kind of storage they should choose for their computer or laptop (i.e., SSD vs. HDD).

In the article below, we have explained the difference between the two that can help you make a decision.

What are they?

A solid-state drive (SSD) is a solid-state storage device that uses integrated circuit assemblies as memory to store data persistently. It is also sometimes called solid-state disk, although SSDs do not have physical disks. A storage device containing non-volatile flash memory, used in place of a hard disk because of its much greater speed.

A hard disk drive (HDD), is an electromechanical data storage device that uses magnetic storage to store and retrieve digital information using one or more rigid rapidly rotating disks (platters) coated with magnetic material. Data is accessed in a random-access manner, meaning that individual blocks of data can be stored or retrieved in any order and not only sequentially. HDDs are a type of non-volatile storage, retaining stored data even when powered off.

Cost

SSD — Expensive as compared to HDD. The cost ranges to roughly $0.20 per GB (for 1TB Drive)

HDD — The cost of HDD is very cheap ranges to roughly $0.03 per GB (for 4TB model)

Power Consumption

SSD — Draws less power (2–3-watts average)

HDD — Draws more power (6–7 watts average)

Capacity

SSD — 1TB maximum for notebooks and 4TB maximum for desktops.

HDD — 500 GB to 2 TB for Notebooks and 10 TB maximum for desktops.

Speed/OS Boot Time

SSD — 10–30 seconds average bootup time

HDD — 30–40 seconds average bootup time

Noise

SSD — No sound

HDD — Very noisy. One can hear the sound of disk spinning

Vibration

SSD — No Vibration

HDD — Spinning of platters can sometime results in vibration

Heat Produce

SSD — Little heat is produced

HDD — More heat is produced as compared to SSD

File Copy/Write Speed

SSD — 200–550 MB/S

HDD — 50–120 MB/S

File Opening Speed

SSD — Up to 30% faster than HDD

HDD — Slower in comparison to SSD

Magnetism Affect

SSD — An SSD is safe from any effects of magnetism

HDD — Magnets can sometime erase data

So, if we compare the points SSD got the maximum point and is a clear winner. It depends on the need of a person to decide what is best for them.

An HDD can be a right choice if:

  • You need more storage space.
  • You need a less expensive device.
  • Or if the OS Boot time doesn’t bother you much.

An SSD can be a right choice for you if:

  • You like to pay for faster performance.
  • Don’t mind limited storage capacity. (though customer can go up to 4TB and 60 TB for enterprise version)
