SSD VS HDD
the difference between a hard drive disk and a solid state drive is that a hard disk drive is a data storage device used for storing and retrieving digital information using rapidly rotating disks coated with magnetic material. An HDD retains its data even when powered off. Data is read in a random access manner, meaning individual blocks of data can be stored or retrieved in any order rather than sequentially. An HDD consists of one or more rigid rapidly rotating disks with magnetic heads arranged on a moving actuator arm to read and write data to the surfaces and a solid-state drive is that (also known as a solid-state disk though it contains no actual disk, nor a drive motor to spin a disk) is a data storage device that uses integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (1/O) hard disk drives, thus permitting simple replacement in common applications. Additionally, new I/O interfaces, like SATA Express, have been designed to address specific requirements of the SSD technology.

infomation vs data
Key difference: Data and information are interrelated. Data usually refers to raw data, or unprocessed data. It is the basic form of data, data that has not been analyzed or processed in any manner. Once the data is analyzed, it is considered as information. Information is "knowledge communicated or received concerning a particular fact or circumstance." Information is a sequence of symbols that can be interpreted as a message. It provides knowledge or insight about a certain matter.
