Unreferenced date December 2009 A portable storagedevice PSD is a small hard drive designed to hold any kind of digital data. This is slightly different from a portable media player , which stores and plays music and movie s. Some are fixed size hard drives of 256GB, 320GB, etc. Newer units are expandable using 2.5 laptop hard drives, allowing for an unlimited storage capacity, which is useful for video and images. When travelling, a portable storagedevice may be a useful alternative to backing up or purging memory card s if a computer is unavailable for downloading. Photography One type of data that may be stored is digital photograph s Raw image format RAW data , transferred from a digital camera . Many PSDs will connect directly to a camera and copy the images, or they may provide a slot for a memory card to plug in, with or without a card reader device. Some early models allow the user to review the images on a colour screen, but at the top end of the market.

Paper datastorage refers to the use of paper as a datastoragedevice . This includes writing , illustrating , and the use of data that can be interpreted by a machine or is the result of the functioning of a machine. A defining feature of paper datastorage is the ability of humans to produce it with only simple tools and interpret it visually. Though this is now mostly obsolete, paper was once also an important form of computer datastorage . History Before paper was used for storing data, it had been used in several applications for storing instructions to specify a machines operation. The earliest use of paper to store instructions for a machine was the work of Basile Bouchon who, in 1725, used punched paper rolls to control textile looms. This technology was later developed into the wildly successful Jacquard loom . The 19th century saw several other uses of paper for controlling machines ...

The altered dielectric constant of the paper at the location of the holes could then be used to read the binary data back into the machine by means of electric sparks of lower voltage than the sparks used to create the holes. This form of paper datastorage was never made reliable and was not used in any subsequent machine. Limits The limits of datastorage depend on the technology to write and read such data. For example, an 8 x10 300dpi 8 bit greyscale image map contains 7.2 megabytes of data assuming a scanner can accurately reproduce the printed image to that resolution ... more details
In computing specifically data transmission and computer storagedatastorage , a block is a sequence of byte s or bit s, having a nominal length a block size . Data thus structured are said to be blocked . The process of putting data into blocks is called blocking . Blocking is used to facilitate the handling of the data stream by the computer program receiving the data. Blocked data is normally read a whole block at a time. Blocking is almost universally employed when storing data to 9 track magnetic tape , to rotating media such as floppy disk s, hard disk s, optical disc s and to NAND flash memory . Most file system s are based on a block device , which is a level of abstraction computer science abstraction for the hardware responsible for storing and retrieving specified blocks of data, though the block size in file systems may be a multiple of the physical block size. In classical file systems, a single block might contain only a part of a single computer file file . This leads to space inefficiency due to internal fragmentation , since file lengths are often not multiples of block size, and thus the last block of files will remain partially empty. This will create slack space , which averages half a block per file. Some newer file systems attempt to solve this through techniques called block suballocation and tail merging . Block storage is normally abstracted by a file system or database management system for use by applications and end users. The physical or logical volumes accessed via block I O may be devices internal to a server, direct attached via SCSI or Fibre Channel , or distant devices accessed via a Storage area network storage area network SAN using a protocol such as iSCSI , or ATA over Ethernet AoE . Database management systems often use their own block I O for improved performance and recoverability as compared to layering the Database management ...

About a particular datastorage media the general meaning datastoragedevice File DDS logo.png right Digital DataStorage DDS is a format for storing computer data on a Digital Audio Tape DAT . DDS uses tape with a width of 3.8mm, with the exception of the latest formats, DAT 160 and DAT 320, which are 8mm wide. Initially, the tape was 60 meters 197 feet or 90 meters 295 ft. long, although advancements in materials technology have allowed the length to be increased significantly in successive versions. A DDS tape drive uses helical scan ning for recording, the same process used by a video cassette recorder VCR . If errors are present, the write heads rewrite the data. Tape drives should be cleaned regularly to be kept in good working order. Backward compatibility between newer drives and older tapes is not assured for examples, see HP s http h20000.www2.hp.com bizsupport TechSupport Document.jsp?objectID lpg50457&locale en US&taskId 101&prodSeriesId 81997&prodTypeId 12169 DDS Media Compatibility Matrix .

A datastorage tag DST , also sometimes known as an archival tag , is a data logger that uses sensors to record data at predetermined intervals. Datastorage tags usually have a large memory size and a long lifetime. Most archival tags are supported by batteries that allow the tag to record positions for several years. Alternatively some tags are solar powered and allow the scientist to set their own interval this then allows data to be recorded for significantly longer than battery only powered tags. Operation Datastorage tags can have a variety of sensors temperature, depth, light, salinity , pressure, pitch and roll, GPS, magnetic and compass. ref http www.fishbio.com environmental consulting and environmental research resources fisheries biology fish marking electronic marking datastorage tag.html ref They can be used internally or externally in fish , marine animals ref http www.star oddi.com resources Files pdf 113 Tagging the starfish.pdf ref or research animals .

Deployment Archival tags archive data to internal memory. Once they are recovered the data is then extracted by the researcher. The tag is generally mounted to the animal either by cutting a slit into the animal, inserting the tag, and sewing the opening closed. Alternatively researchers externally attach tags to animals by running anchor lines through the tag and into the dorsal fin for most fish species.
