Solid State Drive

SSD or solid-state drive is a device that utilizes the integrated circuit storage as memory or flash memory are related to store data continuously without power supply. In contrast to the hard disk drive or HDD wear metal disks with magnetic layer to store data, then the SSD did not have mechanical parts or moving parts.

SSD has become common in recent years because of improving technology and market demands, some producers and consumers still support the HDD as a preferred storage device. Here are the advantages and disadvantages of the SSD:


  1. Faster than hard disk drives: SSDS are no mechanical parts. This is one of the advantages of solid-state drives. Data fragmentation does not occur in the solid-state, differs in its hard disk drive, making it more quickly. SSD reach 25 to 100 times faster than the HDD. This makes the boot process faster, faster file transfer and bandwidth for heavy computing.
  2. Lower power consumption: an HDD consume more power because it moves the motor disc player, also the driving coil sleeve head read and write. SSDS have no moving parts and requires no mechanical work for operation. This low power needs give solid-state drive other advantages, suitable for energy-efficient computers and other electronic devices. Other impacts are low levels of heat.
  3. A longer lifetime: one major weakness of an HDD is the vulnerability to loss of data and damage to the device due to overall collision or a fall. This weakness comes from mechanical parts or moving in the hard disk drive that has a very high precision such as head with the dish. Since SSDS have no moving parts, thus more durable and resistant to collisions or falling. so that makes it more resistant to data loss. This is another worthy advantages of solid-state drives especially when taking into consideration of mobile computing.
  4. No sound/noise posed: the absence of a mechanical movement such as metal plates, round and read write head movement making SDD really quiet while operating. Noise level zero not possible on HDD. Metal plate rotation and movement of the arm head read write cause noise and vibration.
  5. Dimensions that are more compact and lightweight than hard disk drives: SSDS is very compact compared to HDD due to the absence of mechanical or moving parts. Solid-state drive into the storage components more suitable or profitable on the application for portable electronic devices such as tablets and ultrabooks.


  1. The price of the more expensive: SSD is more expensive than HDDS in terms of dollars per GB. This is one of the main disadvantages of solid-state drives. Compared to hard disk drives, solid-state drives with similar storage capacity can be twice as expensive. This translates into a more expensive computer or other device with a solid-state drive system than the people who had the hard drive of the system.
  2. Storage capacity: currently in the SSD market has limited storage capacity. Computer or device with an SSD storage systems usually have basic storage capacity of 128 GB. Higher storage capacity contributed significantly to the overall price of a computer or device. Although there is a solid-state drive with a capacity of 4 TB, they are very rare and expensive.
  3. Rarely available: availability on the market of solid-state drive is rare. HDD is more abundant in the market. The internal storage of a computer or external media storage devices, lebihmudah find the hard disk drives and is much cheaper than solid-state drives. But the consumer electronics market is now starting to go in the direction of more compact laptops and tablet computers. This means the SSD into the needs and more.
  4. Short lifespan compared to hard disk drives: SSDS have limited write cycles. Flash memory solid-state drives can only be used to write a number of limited. SSD can’t write one information without deleting first and then rewrite the very large blocks of data at a time. As each cell goes through this cycle, it becomes more useful. This decrease in process does not affect the ability to read the entire SSD. In addition, advances in technology improve the lifespan of the SSD.
