SSD Vs HDD

You may have heard the term SSD being battered around like a tennis ball on a court lately. We get many computers that come into us that are slow and sluggish and people ask us, is having an SSD worth it. We found a handy chart to show you the difference

HDD SSD
Stands for Hard Disk Drive Solid State Drive
Speed HDD has higher latency, longer read/write times, and supports fewer IOPs (input output operations per second) compared to SSD. SSD has lower latency, faster read/writes, and supports more IOPs (input output operations per second) compared to HDD.
Heat, Electricity, NoiseHard disk drives use more electricity to rotate the platters, generating heat and noise. Since no such rotation is needed in solid state drives, they use less power and do not generate heat or noise.
Defragmentation The performance of HDD drives worsens due to fragmentation; therefore, they need to be periodically defragmented. SSD drive performance is not impacted by fragmentation. So defragmentation is not necessary.
Components HDD contains moving parts – a motor-driven spindle that holds one or more flat circular disks (called platters) coated with a thin layer of magnetic material. Read-and-write heads are positioned on top of the disks; all this is encased in a metal cas SSD has no moving parts; it is essentially a memory chip. It is interconnected, integrated circuits (ICs) with an interface connector. There are three basic components – controller, cache and capacitor.
Weight HDDs are heavier than SSD drives. SSD drives are lighter than HDD drives because they do not have the rotating disks, spindle and motor.
Dealing with vibration The moving parts of HDDs make them susceptible to crashes and damage due to vibration. SSD drives can withstand vibration up to 2000Hz, which is much more than HDD.

As you can see from above, an SSD will perform better.
