The chapter the distinguishing characteristics of primary and secondary storage; describes the devices used to implement primary storage; compares secondary storage alternatives; describe factors that affect storage devices and explains how to choose appropriate secondary storage technologies and devices.
The Future of Data
Storage Technology
Is the future of data storage technology an oldie but goodie?
This article suggests so.
This article suggests that the cassette tape is making a
comeback as far as a data technology is concerned.
A new wave of ultra-dense tape drives developed by Fuji Film
in Japan and IBM in Zurich, Switzerland is going to be used in massive data
farms owned by the likes of Facebook and others.
The first prototypes are four inches square and under an
inch thick. Each can store up to 35
terabytes of data. This density is
achieved by using magnetic tape coated in barium ferrite. The imputus for this
change is the Square Kilometre Array telescope. Once running, this telescope is
predicted to generate about 1 million gigabytes of data per day.
Both IBM and Fuji are working on ways to shrink the
internals of these tapes in order to store as much as 100 terabytes per tape
cartridge.
