The cost of flash storage is reducing, but it is not reducing much faster than the reduction in storage costs for magnetic disk
The US Department of Defense has an often-quoted specification for data shredding on magnetic disk
This automatic process keeps space available on the server's magnetic disks
and leaves room for loading files from the optical storage library.
areal density has grown at an impressive 60% compound annual growth rate historically and has accelerated to greater than a 60% rate since 1999.
Hardware prices for magnetic disk
storage are projected to continue the 30% or greater annual decline for the foreseeable future.
By experimenting with such small magnetic cells, the researchers learned that the behavior of magnetic regions in narrow tracks is similar to that of the much larger regions now found on conventional magnetic disks
As data becomes less active or moves to an archival state, it becomes too costly to leave the data on spinning magnetic disks
for 24x365 consuming electricity, generating heat, and occupying increasingly costly real estate.
Magnetic tape technology has seen a considerable increase of function and capacity, though not on nearly the steady evolutionary path as magnetic disks
Since its inception in 1956 with the RAMAC 350, the evolution of magnetic disks
has continued to produce rich features and increased functionality with each new offering.
1999 The areal density of magnetic disks
exceeds 20 million bits per square inch.
These devices use flash memory chips instead of rotational magnetic disks
to store data.
Automated libraries using magnetic tape, possibly small form-factor magnetic disks
, the DVD, and possibly other emerging storage mediums will become the foundation containing most of this mass-storage growth.
