We all use hard
disk drives as storage solution for our computers. One thing most
people overlook is that, hard disks have a significant part to
contribute towards the performance of your computer. A sluggish hard
drive will slow you down no matter how much faster your processor is
or how much RAM you have installed.
There are mainly two types of hard drives available: Mechanical Hard
Disk Drives (HDD) and the Solid State Drives (SSD).
HDD’s come in
two varieties:
- Hard disks with 5400 RPM spinning speed.
- Hard disks with 7200 RPM spinning speed.
Higher speeds
tend to offer better file transaction speeds.
Mechanical hard
drives have a read/write head which has to move to the correct
location on the disk before the reading of data begins. Hence it is
slower.
SSD’s on the
other hand do not have any physical moving parts. This helps to
eliminate the extra read time and greatly improves the application
loading time. But SSD’s are much more expensive than a mechanical
drive. Hopefully they’ll get easily affordable in the future.
Some advantages
of SSDs compared to HDDs are
- Way faster than HDDs.
- More reliability as there are no moving parts
- Less power consumption with no noise
- Low heat generation.
