SSD (Solid State Drive) hard drives are a method of data storage for devices. They are found mounted onto computer PCBs (printed circuit board), or they can be external. SSDs are a form of Flash memory storage and will each have a capacity, given in MB, GB or TB.
They get their name "solid state" from their use of electric charge to store code, instead of physical moving parts. This means that there are no components that will wear out from movement. They are generally reliable and long-lasting devices.
Benefits:
Fast reading and writing data
No moving pieces
Compact, lightweight devices
Low failure rates
Where are SSDs used?
Servers
Computers
Laptops
Smartphones
Tablets
Memory Sticks
Why choose an SSD hard drive?
Solid State Drives store data continuously. The SSD will store your data, ready to go, even when powered down. This gives it a distinct advantage over a traditional hard drive. If used correctly, the SSD can greatly improve the operating times on your laptop or computer.
SSD Interfaces:
Solid State Drives come with different I/O interfaces such as:
PCIe
SATA
PATA
USB
What is a NAND?
Negative-AND (NAND) is a flash memory storage technology that is able to retain data without power. NAND memory chips house the memory cells. There are various types of NAND memory cells such as; ISLC, MLC, and SLC (single-level cell).
SSD vs. HDD
The SSD hard drive replaces the traditional hard disk drive (HDD) as it is much faster. The HDD has multiple moving parts, whereas the SSD does not. The lack of moving parts enables the SSD to be a lot smaller and require less power to operate.
A Solid State Drive can be used alongside your current HDD. Using the SSD to store your operating system will greatly decrease the initial start-up time of your PC/Laptop. SSDs also have a much lower failure rate than HDDs.
