Redundant Array of Inexpensive Devices is a form of secondary storage device that saves you work on more than one disk. That can mean that work saved on one side of the country can be stored on the other side of the country for greater safety
disk storage-> direct data access storage tape storage -> serial data access storage
MAinframes these days use DASD [direct acess storage device] as the secondary storage next to High speed buffers. Backup of data is done over tape storage. In olden days punch cards where used as they were even cheaper than tapes...
The advantage of programmable logic device is in terms of money. This device is cheaper rather than using microcontrollers that has to be certified before someone can use it.
Electrical energy is continuously obtained.
Secondary sources are better because your not learning the truth you have some story behind it and possible reasons that came to be.

One advantage of a secondary source over a primary source is that it may provide analysis, interpretation, or synthesis of information from multiple primary sources. This can offer a broader perspective or deeper understanding of a topic compared to individual primary sources.
they can reveal how individuals experiencing historical events actually reacted
It is a storage device, usually the main storage on a computer where programming and data are saved. A traditional device can read and write information to the disk, and can be re-used (over-written with new information)
Sparse advantage, less storage space required Dense advantage faster since each index key is directly linked to a record key
