TAPE LIBRARY In computer storage, a tape library, sometimes called a tape silo, tape robot or tape jukebox, is a storage device that contains one o more tape drives, a number of slots o hold tape cartridges, a barcode reader to identify tape cartridges and an automated method for loading tapes (a robot). Addiotionally, the area where tapes that are not currently in a in a silo are stored is also called a tape library. Tape libraries can contain millions of tapes. These devices can store immense amounts of data, ranging from 20 terabytesr up to 2.1 exabytes of data as of 2016. Such capacity is multiple thousand times that of a typical hard drive and well in excess of what is capable with network attached storage.Typical entry-level solutions costs around $10.000 USD, while high-end solutions can start at as much as $200.000 USD and costs well in excess of $1 million for a fully expanded and configured library. For large data-storag, they are a cost-effective solution, with cost per gigabyte as low as 2 cents USD. The tradeoff for their larger capacity is their slower access time, which usually involves mechanical manipulation of tapes. Access to data in a library takes from several seconds to several minutes.
MASS STORAGE In coomputer, mass storage refers to the storage of large amounts of data in a persisting and machine-readable fashion.Devices and/or systems that have been described as mass storage include tape libraries, RAID systems, and variety of computers drive such as hard disk drives, magnetic tape magnetooptical disc drives, optical disc drives, memory cards, and solid- states drives. There are two broad classes of mass storage: local data in devices such as smarthphones or computers, and enterprise servers and data centers for the cloud. For local storage, SSDs are on the way to replacing HDDs.Considering the mobile segment from phones to notebooks, the mayority of the system today is based on NAND Flash.As Enterprise data centers, storage tiers have established using mix of SSD and HDD. Mass storage devices used in desktop and most server computers typically their data organized in a file system. The choice of file system is often important in maximizing the preformance of the device.
DATA PROTECTION & LONG TERM STORAGE ARE MORE IMPORTANT THAN EVER Tape has been used for decades to preserve and protect data, and today more than ever tape is the best choice for long term storage. Not only that,but tape has emerged as a key part of cloud and hyperscale infrastructures. The biggest data center on the planet are using tape, and using it extensively. Companies are dealing with a challenge of storing petabytes, and exabytes of unstructured data- video, hi-res images, loT data, research data, really valuable stuff- and they need to keep it fpr decades. Further, in Enterprise, CIOS and IT departments are converned with the threat of rasonware. Because tape storage is an 'offine' storage technology, it provides efffective protection against ransomeare and malware.
