...WHEN YOU'RE IN front of your PC, waiting for something to transfer to removable media, seconds can feel like minutes, and minutes like hours. And backups to USB 2.0 appear to crawl along at a snail's pace--so much so that users often become reluctant to perform that essential chore. Such data-transfer scenarios are where the new SuperSpeed USB 3.0 standard and its theoretical, blazing-fast throughput of 5 gigabits per second--as promised by the USB Implementers Forum (USB-IF)--will change your life for the better. And if our tests of four new USB 3.0 hard drives from Buffalo Technology, Iomega, Seagate, and Western Digital are indicative, the change will certainly be dramatic. USB 3.0's impressive speed is its raison d'être, part of its beauty is its backward compatibility with USB 2.0. You need a new cable and a new host adapter (or one of the new motherboards built to but support USB 3.0) to achieve USB 3.0 performance. But you can still use a USB 3.0 device on a USB 2.0 port and achieve typical USB 2.0 performance. You may also use USB 2.0 devices on a USB 3.0 port--though, again, with no gain in speed. The technology behind USB 3.0 more closely resembles PCI Express than USB 2.0. Backward compatibility comes from clever connector design, and a dual bus. The designers added four data lines and a ground wire for the new USB 3.0 signals, and retained the existing pair of data lines for use with USB 2.0 devices. The two technologies share the existing power and ground wires...

...The Price of RAM And Hard Drive Storage Over The Past 30 Years The price and capacities of RAM and hard drive storage have come a long way in the past 30 years. Take for instance, in 1981 an 18MB hard drive cost $2500, today a 1TB hard drive costs $150. In 1990 RAM costs were $50 per MB and today one can purchase 2GB RAM for approximately $50. Observe the following table pertaining to hard drive cost vs GB capacity from 1980-2009: Table Source: iStockAnalyst Observe that there is a strong exponential correlation in the capacity vs cost ratio, where r=0.9916. During the last 30 years the capacity per unit cost ratio has nearly doubled approximately every 14 months. The regression equation is given by: Many TB+ drives have become available which recently broken the $0.10/GB boundary, whilst the next milestone being $0.01/GB or $10/TB. If historical trends continue, then 10 years from now the cost per GB of hard drive capacity will become $0.0000351 per GB or $0.0351 per TB. For $100, one could purchase a 2,849TB drive 10 years from now, based on the analysis of historical trends. Although 120 PB drives are currently available in the server and super computing market, consumer grade hard drives aren’t available in these sizes, as the physical size and cost per PB is too great for the marketability in the consumer market. Based on historical trends, one could forecast the availability of a consumer level 100TB hard drive in the next five years. It must be noted all figures...

...polarization of small patches of the surface coating on a (normally) metal disk. The maximum areal density is defined by the size of the magnetic particles in the surface, as well as the size of the "head" used to read and write the data. The areal density of disk storage devices has increased dramatically since IBM introduced the RAMAC, the first hard disk in 1956. RAMAC had an areal density of 2,000 bit/in². Commercial hard drives in 2005 typically offer densities between 100 and 150 Gbit/in², an increase of about 75 million times over the RAMAC. In 2005 Toshiba introduced a new hard drive using perpendicular recording, which features a density of 179 Gbit/in².[1] Toshiba's experimental systems have demonstrated 277 Gbit/in², and in 2006 Seagate Technology demonstrated a drive with a 421 Gbit/in² density.[2] It is expected that perpendicular recording technology can scale to about 1 Tbit/in² at its maximum. [3] Compact Discs (CDs), another common storage media of the early 2000s, stores data in small pits in plastic surface that is then covered with a thin layer of reflective metal. The standard defines pits that are 0.83 micrometers long and 0.5 micrometers wide, arranged in tracks spaced 1.6 micrometers apart, offering a density of about 0.90 Gbit/in². DVD disks are essentially a "product improved" CD, using more of the disk surface, smaller pits (0.64 micrometers), and tighter tracks (0.74 micrometers), offering a density of about 2.2 Gbit/in². Further improvements in HD...
