What is a Solid State Drive?
A solid state drive is a technology that replaces conventional computer hard disk drives that use a spinning disk. From the 1980's until around 2012, the primary storage system on computers used a hard drive with a spinning disk and a read/write head that reads and writes data to the disk. Solid state drives use flash memory technology to store data instead.Tablet computers use solid state drives instead of hard drives. Shock or vibration can cause damage to a hard drive- solid state drives can withstand much more abuse since they have no moving parts.
What is SSD?
SSD is an acronym that stands for "Solid State Drive".What are the Advantages of a Solid State Drive?
A solid state drive has no moving parts and is more reliable than a hard disk drive. Since solid state drives use flash memory, random access of data is possible. This characteristic makes access of many types of computer files faster from a solid state drive than a hard drive. Solid state drives do not suffer from fragmentation since random access of data is supported- defragmentation of solid state drives is not needed.What are the Disadvantages of Solid State Drive?
Currently, solid state drives cost several times more for the same capacity as a hard disk. Also the maximum size of available solid state drives is smaller than the largest size of hard drives that is available. Hard drives can provide higher data rates for sequential access of data such as video files.This external solid state drive costs about $100 for 128 GB of storage:
This external hard drive costs about $70 for 1 TB (1000 GB) of storage:
