Abstract:
This is the description brings the brief about the today's and time to come computer warehouse options. Most of ours using computers and systems, but we do not know much more details about the warehouse and warehouse options existing today. For those people, you can in fact get to know about the brief introduction and overview of nowadays warehouse options - personal and company from this article.
Scsi To USB
Hard Disk Drive:
If anything hears about computer storage, suddenly he might have think about this hard disk only. It is a coarse warehouse option, most of the Pc's have. After 1990, the evolutions of hard disk come to be more and more. So it in fact occupies our Pc's without any competitions of other warehouse options. Assess to other warehouse options this is the smartest storage, suitable for personal computers. There are two main types of hard disks are used in today's systems. They are,
o Magnetic Hard Disks
o Solid State Disks
Magnetic Hard Disks:
Magnetic Hard Disk Drive is a digital data warehouse device that reads and writes data via magnetization changes of a magnetic warehouse disk. This includes one or more randomly accessible rotatable warehouse media, or disks. Nowadays magnetic hard disks are there in store up to terabytes. Yes, a singular hard disk drive has that much memory like a big warehouse server. The first commercial magnetic Hdd introduced by Ibm in 1956 having 5Mb storage. But last year Hitachi introduced 1Tb magnetic Hdd. This year 2008, Seagate announced 1.5 Tb Hdd for personal and company purposes. This Hdd are having data exchange rate is nearly 16 to 20 Mb/s.
Solid State Disks:
The develop of solid-state disk starts with combining the each block like Flash memory, Memory controller, Ram, Ram Controller, Processor and Host etc., M-Systems introduced first flash-based solid-state drives in 1995. (SanDisk acquired M-Systems in November 2006). Since then, flash based Ssds demands high in soldiery and aerospace industries, as well as other mission-critical applications. Nowadays in Ssd, Flash is used as a permanent warehouse and Ram is used as a temporary warehouse in the middle of Flash and processor to increase the performance.
It's very suitable for small hand held systems and note books, because it does not have arresting parts, requires less power, Host data exchange rate of up to 3Gb/s and silent operation. Up to 2007 middle only 64Gb (Samsung & SanDisk) solid-state drives are there in the store with in the size that is compatible with notebooks. In this year Samsung announces a super-fast 256 Gb, 2.5-inch solid-state drive. 'Super Talent' has announced the world's thinnest 256 Gb 2.5-inch Ssd drive. Toshiba also launched 3 Mlc flash Ssd families with Sata interfaces.
Optical Disks:
The main uses of optical warehouse disks are article exchange, backup and archiving and not for traditional storage. It's having capacity from 300 Mb to 30 Gb. Before the evolutions of optical warehouse Disks, the Magnetic floppy disks are used for data exchange and for small storages. Because of the very limited warehouse (1.44 Mb) and small life period of floppy, the optical disks had overtaken that. There are four main commercial types of optical disk's are there for present day usage. They are,
o Laser Disks
o Compact Disks (Cd)
o Digital Versatile Disks (Dvd)
o Blu-Ray Disks (Bd)
Laser Disks:
The laserdisc was the first optical warehouse medium used for commercial purposes, particularly for the movie industry. Paul Gregg invented the laserdisc technology in 1958, development use of a transparent disc. Laserdiscs are celebrated in 80's for audio songs and although the Vhs (Video Home System) cassettes and the Cd/Dvd format has overtaken the Laserdisc in usage. It looks 30 centimeters in diameter and it is made up of two single-sided discs. Laserdisc is in fact an analog format unlike Cds or Dvds which are digital. Now Laser disks doesn't have any market, but still some population are using this to hear old songs.
Compact Disks:
The most coarse form of optical warehouse is the compact Disk (Cd). Even with the arrival of other more superior optical media, Cds remain a beloved way for industries to box software, games, music, and movies. These discs provide low-cost and easy-to-use back-up for and corporal exchange of data files. Regularly compact disks are arrival in two ways. One is Cd-R (one time write and more estimate of reads) and Cd-Rw (More estimate of read and writes). A approved Cd has a capacity of about 74 minutes of approved Cd audio music and holds about 700 Mb. But actual capacity depends on the format of writing.
Digital Versatile Disks:
This is the improved form of compact disks, commonly known as Dvd. It has another expansion like Digital Video Disks also. It also contains Dvd-R and Dvd-Rw divorce like the above. A approved Dvd offers 4.7 Gb (Single Layer) / 8.5 Gb (Dual Layer) storage. But it looks similar like Cd. We can read/write the Cds in the Dvd Writer, but Cd writer won't read the Dvd.
Blu-Ray Disks:
It is the next-generation optical disks, able to hold high-definition video and other high-density storage. A single-sided Blu-ray disk can hold 25 Gb of storage, while a dual-sided one can store 50 Gb. The Blu-ray disk's size is similar to that of the Cd and the Dvd - 120 mm in diameter. It uses 405 nm wavelength of laser, so only it named as a Blu-ray disk. It has 54 Mbps exchange rate is first-rate to both the Cd (150 Kbps) and the Dvd's (11.1 Mbps). Blu-ray discs are more expensive and slower to manufacture, in general used for Game warehouse like play stations.
Raid:
It is wide like Redundant Array of Independent Disks. It is a technology that employs the simultaneous use of two or more Hard disk drive to perform greater levels of performance, reliability, and/or larger data volume sizes. A Raid distributes data over any corporal disks. There are three dissimilar types of Raid concepts. They are,
o Software Raid
o Hardware Raid
o Firmware/driver based Raid
Tape Storage:
The main usage of tape warehouse is offline warehouse and backup for traditional storage. Today's magnetic tape is most commonly packaged in cartridges and cassettes. Tape drives can be associated to a computer with Scsi commonly and Fibre Channel, Ficon, Escon, parallel port, Ide, Sata, Usb, FireWire or other interfaces also. It has the following prominent benefits.
o It offers bottom cost per megabyte of all warehouse media options.
o Extremely high capacity per cartridge.
o Portable
The same like it has some limitations also.
o Very slow operation (both read and write)
o Relatively short operational life Assess to other warehouse media
o Subject to deterioration and environmental hazards
The inequity in the middle of tape data warehouse and disk data warehouse is that tape is an Sequential access medium while disk is a random access medium. Nowadays Tape warehouse is used to store data's, which doesn't need, but should have a Backup like Hospital passed away patients record.
Network Attached Storage:
It is commonly known as Nas, used for company warehouse as a server. These devices contains embedded processors that run some sort of operating theory or microprocessors that understands networking protocols and is optimized for singular tasks, such as file aid and network backup etc., Nas is an ideal choice for organizations finding for a easy and cost-effective way to perform fast data access for many clients at the file level. Some prominent benefits of Nas are listed below.
o Files are in fact shared among users at high interrogate and performance
o Files are in fact accessible by the same user from dissimilar locations
o Demand for local warehouse at the desktop is reduced
o Storage can be added more economically and partitioned among users-Highly scalable
o Data can be backed up form the coarse repository more efficiently than from desktops
o Multiple file servers can be consolidated into a singular managed warehouse pool
Storage Area Network:
It is commonly known as San. It is a high operation warehouse network that transfers data in the middle of servers and warehouse devices, detach from the local area network. For a normal person these two, San and Nas are giving big confusion. These two are used as server warehouse but the main inequity is, Nas uses Lan but San won't use it. Some advantages of San over Nas are listed below.
o Superior Performance
o Reduces Network bottlenecks
o Highly Scalable
o Allows backup of warehouse devices with minimal impact on yield operations
o Flexibility in configuration.
Online Backup:
The above said methods are suitable and quick, and many offer fullness of reasonable warehouse space. For Enterprises, the big question is arrival at the time of disaster, hurricane, earthquake, fire occurs, both the computer and the data backup servers could be destroyed. There's also the question of theft, of course. But online backup services, which save the most essential computer files on a secure, off-site server over the Internet.
Online Backup means remote Backing up Services. That is taking backup via the Internet to a remote location can safe against some worst-case scenarios mentioned above. A drawback of this an Internet association is Regularly substantially slower than the speed of local data warehouse devices and it also has the risk associated with putting operate of company secrets data in the hands of a third party.
