The center incorporates advanced video processing calibrated to the DCI (Digital Cinema Initiative) color standards recently adopted by most Hollywood studios and distributors, as well as removeable-hard-disk data storage to accommodate multiple DCI-standard motion picture titles ready for immediate playback.
ENGADGET: SIM2 tag-teams with Entertainment Experience to bring you movies on hard drives
They also found a Compaq personal computer holding on its hard disk some two gigabytes of encrypted data.
This model is driving the growth of digital storage in data centers and thus the sale of hard disk drives, tape storage and flash memory used in enterprise storage tiers for these data centers.
FORBES: Changing Digital Storage Requirements for Clouds and Mobile Devices
The flash memory in the Fusion Drive moves data and applications frequently accessed by the user to the flash memory and move less frequently used data to the hard disk drive as the flash memory becomes full.
FORBES: Will A Fusion Drive Approach Become Widespread in Computers?
Retrieving and storing data from a hard-disk drive takes one million times longer than accessing it from server memory, a difference that can severely degrade application performance.
In addition to a higher storage capacity than past LTO generations, LTO 5 also offers new architecture features such as the LTFS file system that turn magnetic tape into a directly addressable data source, like a hard disk drive.
The technology, called RAID (redundant arrays of independent disks), involves clever algorithms for dealing out data among an assortment of hard-disk platters.
Perhaps the biggest gain may be in dual storage computers where a flash memory device is used for storing operating systems, software and frequently accessed content (and maybe even for write caching) while a hard disk drive provides much less expensive mass storage of user data.
For decades, hard-disk makers have been shrinking the electromagnetic media that store data to cram more information into a tinier footprint.
The flash cache is used to store frequently accessed data providing the fast data response found in solid state drives while the hard disk storage provides low cost storage.
FORBES: New Seagate Solid State Hybrid Drive is Faster and Vaster
That's significant because analyzing or manipulating data in memory is much faster than retrieving it from a hard disk.
The bulk of digital content in data centers will remain on magnetic storage media either hard disk drives or magnetic tape.
It also makes it easier to find the files that have been created, accessed and modified during an attack, and it is able to reconstruct deleted files from raw data found in various hidden parts of a computer's hard disk, such as unallocated space and file slack.

After you configure your backup, Google zips your data into an archive that you can download and store on a hard disk under your bed or in a bank vault in Geneva.

Of course the total energy used by a hard disk drive depends upon the actual usage and power saving modes, and caching of data can reduce the energy used by a HDD in a computer system.
FORBES: Seagate Discontinuing 7,200 RPM Drives--A Focus on Capacity?
Regarding the longevity of storage media many of the products that we use today, hard disk drives, flash memory, optical discs and magnetic tape will react with the ambient environment and gradually lose the data stored on them or disintegrate over time.
