How Solid State Storage Works

Solid state storage is an increasingly popular alternative to other storage media. It is often also referred to as flash storage or flash memory.

Storing a bit

Storing a bit

Solid state drives are made of flash memory.
Flash memory stores the value of each bit in a semi-conductor chip.

Accessing data

Accessing data

Data can be accessed randomly. This means that any piece of data can be accessed in a constant amount of time.
This is achievable because there are no moving parts.

Reliability

Reliability

Solid state drives (SSDs) are robust. They are not easily damaged by shocks because they don't have any moving parts.
SSDs have a limited number of read/write cycles. After a certain number of re-writes they will stop working.
