Now for details on SSD vs HDD:
HDD
How it works:
HDD consist of one or more magnetically sensitive platters, an actuator arm with a read/write head on it for each platter. A motor to spin platters and move arms. An I/O controller and firmware tells the hardware what to do and communicates with the rest of the system.
The platters spin at preset speeds i.e. 4200 rpm to 7200 rpm for consumer computers. Those speeds correlate to read/write rates. The higher the preset speed, the faster a HDD will be able to read/write data.
Drawbacks of HDD:
Its drawbacks are a result of the mechanical parts used to read / write data, as physically retrieving data takes more time than that of electronically. The mechanical parts can skip or fail if they are dropped or not handled properly. HDDs are heavier and use energy than comparable to SSDs.
Benefits of HDD:
The benefits of hard disk drive are that they are a well known and proven technology. They are frequently less expensive than a SDD for the same storage capacity. Currently, HDDs are available with more storage capacity than SSDs.
SSD
How SSD works (NAND technology)?
We can call SSD a large USB drive as both of them use the same base technology i.e. NAND. NAND, the technology in SSD, is a kind of flash memory. At the lower level, floating gate transistors record a charge to store data. The gates are organized into a block. An SSD controller that performs several functions, including keeping track of where data is located.
Drawbacks of SSD:
SSDs are based on newer technology. They are more expensive than HDDs. The lifespan of an SSD isn’t as long as that of an HDD. It can be harder to find large capacity SSDs. HDDs are approx. 2.5 times larger than SSDs.
Benefits of SSD:
It do not use mechanical parts so lose of data is low. SSDs deliver faster load times for games, application, and movies. Due to its technology, they are lighter and better able to withstand movement and drops. In addition, Solid state drive use less energy, allowing computers to run cooler.
