The Hitachi Deskstar 7K100, though pretty expensive at this juncture delivers for its price and stays atop competition for 1 TB hard drives and other storage formats using new technology. Portable USB 3.0 2TB 1TB 500G External Hard Drive Disk HDD 2.5'' Fit For PC Laptop 3+ day shipping Dcenta 2.5inch Portable External Hard Drive USB 3. The seek times are a nominal 8.5ms for writing and 9.2ms for reading.Īt $400 for the 1TB hard drive, this monster is all about speed and functionality. Thus the SATA (Serial ATA) disc is capable of interface speeds of up to 3 GB/s – quite high for a normal 3.5 inch drive. Though the speed is not very fast (hence accessing time is longer), perpendicular recording takes care of the data access speeds, making sure the time of access is not too high. With 5 platters reading 250 GB each, and the data being recorded vertically, Hitachi’s Deskstar 7K100 is a state of the art 3.5 inch rotating disk drive at 7200 rpm. Wholesaler of Hard Disk Drive - Seagate Surveillance Hard Drive 2 TB, Seagate Surveillance Hard Drive 1 TB, Seagate Surveillance Hard Drive 8 TB and WD.
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. These innovations and other data storage techniques led to the formation of the first 1 (one) Terabyte hard drives.
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. They made a promise in mid 2005 that they would make 1 Terabyte hard discs by end 2007. The first proponents of the 1 TB hard drives were the folks at Hitachi. The technology used in these hard drives is the latest and one of the most advanced since the advent of rotating hard drives.
#Hard disk drive 1tb upgrade#
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. 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). This means that the computer must have access to databases stored in physical storage devices that can store electronic data in a vast amount. The Microsoft Windows family of operating systems uses the binary convention when reporting storage capacity, so an HDD offered by its manufacturer as a 1 TB drive is reported by these operating systems as a 931 GB HDD.

Computers are meant for processing vast amounts of data in a relatively short time with a freer access to all the data. Software reports hard disk drive or memory capacity in different forms using either decimal or binary prefixes.
