Solid State Drive (SSD)

A solid state drive (SSD) is a data storage device that uses solid-state memory to store persistent data. An SSD emulates a hard disk drive interface, thus easily replacing it in most applications. Flash memory is increasingly being used for so called Solid State Drives, which are intended to replace the hard drive where performance takes priority over capacity. The good old HDD is constrained by mechanical components, which prevent quicker access times andperformance.

SSD's comes with 2.5" and 3.5" in size that's fit great on your Desktop PC or Notebook and you can have capacity up to 256 GB in size .


  • Faster start-up, as no spin-up is required
  • Typically, fast random access for reading, as there is no read/write head to move
  • No noise
  • For low-capacity flash SSDs, low power consumption and heat production when it's active
  • Ability to endure extreme shock, high altitude, vibration and extremes of temperature
  • lower weight and size

  • Cost
  • Capacity
  • Limited write (erase) cycles
  • Slower write speeds
