Non volatile memory

Non volatile memory is a type of computer memory which can retain any information that has stored or saved before power goes off and not powers as well, all the information will still remain. Read only memory (ROM), flash memory, hard disk drive, floppy disk, optical discs are all example of non volatile memory (http://en.wikipedia.org/wiki/Non-volatile_memory, n.d.).

Hitachi Global Storage Technologies was the first to produce a hard disk drive that has the capacity of 1 Terabytes (1TB) in the year 2007 (http://news.cnet.com/2100-1041_3-6147409.html, 2007).

Seagate followed by producing a hard disk drive that has the capacity of 1.5 Terabytes (1.5TB) in the year 2008 (http://techreport.com/articles.x/15730, 2008).

In the year 2009, Western digital was the first to produce a hard disk drive that has the capacity of 2 Terabytes (2TB) with spindle speed of 5,400 RPM (http://www.bit-tech.net/hardware/storage/2009/10/02/western-digital-2tb-caviar-black-review/1, 2009).

1 Terabytes hard disk drive has 32MB cache which is twice the size of any hard disk before its production and because of its large cache (http://hardware.gwn.com/reviews/review.php/id/136/title/Hitachi_Deskstar_7K1000_1_TB_Hard_Drive.html, n.d.), transfer of information is very fast, so hundred of Terabytes will be very faster than the existing 1 and 2 Terabytes hard drives.

Another effect of having hundred of Terabytes hard drive is that data recovery services will definitely become more complex by the day and also expect the more capacity the more data to lose too (http://www.buzzle.com/articles/what-terabyte.html, 2007).

With hundred of Terabytes hard drive, data processing will be very fast and it will also enable computer users to store large data especially those media, music production.
