SSD (Solid State Drive)

SSD- Solid State Drive. This drive does not have any moving part similar to a USB drive. SSD a very large and more sophisticated type of a USB. Like a memory stick, the information on the SSD is stored in the form of micro-chips. Instead of having the data being accessed by a mechanical arm, SSDs are able to access it directly from the micro-chip. This is the reason why the SSD is far speedier than the HDD as it requires less manual labor for getting information.

SSDs available today can keep the data stored for up to 200 years. has an embedded processor which is termed as a controller. It is used for performing various operations which are related to data reading and writing. The faster the controller the faster are the data read and write speeds. It utilize NAND-based flash memory which is a non-volatile memory type.

HDD (Hard Disk Drive)

HDDrives are an older technology which was discovered almost 60 years ago. It makes use of magnetism for the purpose of storing data. HDD have a rotating platter that spins at high speeds while a read or write head is placed above it which reads and writes data on the spinning platter.

The performance of an HDD is dependent on the spinning speed of its platter. The usual spinning range of HDD drives in use today is 5400 RPM to up to 7200 RPM. Sever-based platters can reach spinning speeds of up to 15000 RPM. The thing that makes HDDs most suitable for data storage is that they are extremely cheap. They can store amounts of data and won’t cost you more.
