  • TAG : PS4 1 Terabyte Hard Drive Upgrade - Step by Step
  • Or in digital terms... the biggest iPod Classic stores 160GB, or about 40,000 songs. Six of those iPods would hold almost one terabyte, enough space to store a quarter-million songs. If you had a shiny new 1-terabtye hard drive, you could stash 300 feature length films, or 40,000 faxes on it. But you'd need 20 of those 1 TB drives to hold the entire print collection of the U.S. Library of Congress.

    In what can only be described as the hard drive equivalent of Game of Thrones, Western Digital’s HGST has announced the world’s first 10-terabyte hard drive: the helium-filled Ultrastar He10. This comes just a few weeks after Seagate announced initial availability of its 8TB air-filled hard drive, which at the time was the largest hard drive in the world. There’s no word on pricing yet but Western Digital says, somewhat unbelievably, that the 10TB drive will have the lowest cost-per-gigabyte and power consumption-per-gigabyte of any drive on the market.

  • Computers are meant for processing vast amounts of data in a relatively short time with a freer access to all the data. This means that the computer must have access to databases stored in physical storage devices that can store electronic data in a vast amount. Starting with magnetic storage devices to the sleek Blu-Ray devices that store an unprecedented amount of data in the same form factor as that of a Compact Disc (CD). It was only a matter of time before hard drives got an upgrade to their storage capacity, and 1 (one) Terabyte Hard drives were invented that could store up to 1000 GB (or one Terabyte) of memory. The technology used in these hard drives is the latest and one of the most advanced since the advent of rotating hard drives.

    A terabyte (commonly abbreviated TB) is a measurement term for data storage capacity.

    The number of bytes in a terabyte is sometimes stated to be approximately 1.0995 × 1012. This difference arises from a conflict between the long standing tradition of using binary prefixes and base 2 in the computer world, and the more popular decimal (SI) standard adopted widely both within and outside of the computer industry. Standards organizations such as IEC, IEEE and ISO recommend to use the alternative term tebibyte (TiB) to signify the traditional measure of 10244 bytes, or 1024 gibibytes.

    The capacities of computer storage devices are typically advertised using their SI standard values, but the capacities reported by software operating systems uses the binary values. A NTFS formatted terabyte hard drive shows 931 gigabytes of free, usable storage space under Windows XP.

    Most users prefer to calculate unit conversions using the binary definition, so this site uses non-SI units.

    I just saw an ad for a Terabyte hard drive. What exactly is a terabyte?

  • The first proponents of the 1 TB hard drives were the folks at Hitachi. They made a promise in mid 2005 that they would make 1 Terabyte hard discs by end 2007. They were quoted as saying that they will use perpendicular recording, a technique to write data vertically in the rotating disc instead of the norm of writing data horizontally and create a new material for recording the data. These innovations and other data storage techniques led to the formation of the first 1 (one) Terabyte hard drives. The 3.5 inch drive that Hitachi produced was a marvel that was designed that not only broke the barriers of storage capacity but also introduced new concepts that were fully integrated into the common knowledge of computer manufacture.

Unboxing: Hitachi 3 Terabyte Hard Drive

When referring to a megabyte for disk storage, the hard drive manufacturers use the standard that a megabyte is 1,000,000 bytes. This means that when you buy an 250 Gigabyte Hard drive you will get a total of 250,000,000,000 bytes of available storage. This is where it gets confusing because Windows uses the 1,048,576 byte rule so when you look at the Windows drive properties a 250 Gigabyte drive will only yield 232 Gigabytes of available storage space, a 750GB drive only shows 698GB and a One Terabyte hard drive will report a capacity of 931 Gigabytes. Anybody confused yet? With three accepted definitions, there will always be some confusion so I will try to simplify the definitions a little.
