Hitachis' 1TB drive-source from HitachiGST
Hitachi's 1TB products deliver the performance and reliability required for the digital lifestyle. The 3.5-inch, 7200 RPM Parallel-ATA/Serial-ATA hard drives are built on the industry's most reliable perpendicular magnetic recording technology, first established with Hitachi's Travelstar 2.5-inch and 1.8-inch product lines.
Maximizing Value - The "Smart" Hard Drive
Hitachi is focused on maximizing the value of the hard drive by spearheading the era of the "smart" hard drive. Customized features have been incorporated into Hitachi's hard drives, tailoring them for the application-set that they serve. To that end, Hitachi's 1TB hard drives are targeted to two distinct application areas:
Deskstar 7K1000 – gaming and high-performance PCs, external storage devices and upgrade applications
SATA 3.0Gb/s and PATA-133 interfaces
Ramp load design for increased shock protection
Three low-power idle modes to boost power efficiency
CinemaStar 7K1000 – DVR applications
Adaptive error recovery and SMART command transport for optimized video streaming and picture quality
Smooth Stream Technology to optimize the drive for audio/video applications requiring reliable storage
"Bedroom quiet" acoustics Finally, an enterprise version of the TB drive designed for lower duty-cycle, high-capacity enterprise environments is currently under evaluation at major OEM customers and is expected to be available in the second quarter.
Pricing and Availability for the Deskstar 7K1000
The Deskstar 7K1000 SATA version will be available in Q1 2007 at 750-GB and one-TB capacities. The 1TB capacity point will have a suggested retail price of $399 (USD).

I doubt it will reach 1070Mbps. Even the 150GB Raptor can reach 90MBps (or 720Mbps) max data rate. We'll just have to wait and see.

i'm not sure about this... i think Curtis HyperXCLR must be the fastest 3.5" solid state disk on the planet....
Using innovative packaging and patent pending ASIC technology, Curtis developed the HyperXCLR in a standard low profile SCA hard drive footprints making it a truly plug and play solution. The HyperXCLR appears as standard disk drive to the operating system or storage controller, no special software drivers are needed. The HyperXCLR solid state disk is a direct replacement for slower rotating mechanical SCA Fibre drives, accelerating database and e-business applications. The HyperXCLR can be integrated as an OEM component providing storage systems a tier of extended cache memory.

But I think the fastest consumer hard drive is the Gigabyte's i-RAM. But none of these state-of-the-art HDDs are not practical for us. :(

U r just wrong bro.This is frm wikipedia..u can read the full article by typing flash memory.I just post the history here.U can see that flash is actually found in 1984..
Flash memory History
Flash memory (both NOR and NAND types) was invented by Dr. Fujio Masuoka (http://en.wikipedia.org/w/index.php?title=Fujio_Masuoka&action=edit)Toshiba (http://en.wikipedia.org/wiki/Toshiba) in 1984 (http://en.wikipedia.org/wiki/1984). According to Toshiba (http://en.wikipedia.org/wiki/Toshiba), the name 'Flash' was suggested by Dr. Masuoka's colleague, Mr. Shoji Ariizumi, because the erasure process of the memory contents reminded him of a flash (http://en.wikipedia.org/wiki/Flash_%28photography%29) of a camera. Dr. Masuoka presented the invention at the IEEE (http://en.wikipedia.org/wiki/IEEE) 1984 International Electron Devices Meeting (IEDM) held in San Jose, California. Intel (http://en.wikipedia.org/wiki/Intel) saw the massive potential of the invention and introduced the first commercial NOR type flash chip in 1988 (http://en.wikipedia.org/wiki/1988). while working for
NOR-based flash has long erase and write times, but has a full address/data (memory) interface that allows random access (http://en.wikipedia.org/wiki/Random_access) to any location. This makes it suitable for storage of program code that needs to be infrequently updated, such as a computer's BIOS (http://en.wikipedia.org/wiki/BIOS) or the firmware (http://en.wikipedia.org/wiki/Firmware) of set-top boxes (http://en.wikipedia.org/wiki/Set-top_box). Its endurance is 10,000 to 1,000,000 erase cycles. NOR-based flash was the basis of early flash-based removable media; Compact Flash (http://en.wikipedia.org/wiki/Compact_Flash) was originally based on it, though later cards moved to the less expensive NAND flash.
NAND flash, which Toshiba (http://en.wikipedia.org/wiki/Toshiba) announced at ISSCC (http://en.wikipedia.org/wiki/ISSCC) in 1989 (http://en.wikipedia.org/wiki/1989), followed. It has faster erase and write times, higher density, and lower cost per bit than NOR flash, and ten times the endurance. However its I/O interface allows only sequential access (http://en.wikipedia.org/wiki/Sequential_access) to data. This makes it suitable for mass-storage devices such as PC cards (http://en.wikipedia.org/wiki/PCMCIA) and various memory cards (http://en.wikipedia.org/wiki/Memory_card), and somewhat less useful for computer memory. The first NAND-based removable media format was SmartMedia (http://en.wikipedia.org/wiki/SmartMedia), and numerous others have followed: MMC (http://en.wikipedia.org/wiki/Multi_Media_Card), Secure Digital (http://en.wikipedia.org/wiki/Secure_Digital), Memory Stick (http://en.wikipedia.org/wiki/Memory_Stick) and xD-Picture Cards (http://en.wikipedia.org/wiki/XD-Picture_Card). A new generation of these formats is becoming a reality with RS-MMC (Reduced Size MultiMedia Card), the micro- and miniSD variants of Secure Digital and the new USB/Memory card hybrid Intelligent Stick (http://en.wikipedia.org/wiki/Intelligent_Stick). The new formats exhibit a greatly reduced size, usually under 4 cm².

I wasn't talking about the technology:rolleyes: :rolleyes: I was talking about the size!!
Though they may have found technology in 1984, when did pen drives actually came out!! or such small storing devices for that matter!!!

Here is about first flash drive in 1998...
The flash drive was first invented in 1998 by Dov Moran, President and CEO of M-Systems (http://en.wikipedia.org/w/index.php?title=M-Systems&action=edit) Flash Pioneers (Israel). Dan Harkabi, who is now a Vice President at SanDisk (http://en.wikipedia.org/wiki/SanDisk), led the development and marketing team at M-Systems. His most significant contribution was his insistence that the product be self-reliant and free of the need to install drivers. Nearly simultaneous development of similar products was undertaken at Netac (http://en.wikipedia.org/w/index.php?title=Netac&action=edit) and at Trek 2000, Ltd. All three companies have similar and disputed patents. IBM (http://en.wikipedia.org/wiki/IBM) was the first North American seller of a USB flash drive, and marketed an 8 MB version of the product in 2001 under the "Memory Key" moniker. IBM later introduced a 16 MB version manufactured by Trek 2000, and returned to M-Systems for the 64 MB version in 2003. Lexar can also lay claim to a pioneering USB flash drive product. In 2000 they introduced a Compact Flash (http://en.wikipedia.org/wiki/Compact_Flash) (CF) card having an internal USB function. Lexar offered a companion card reader and USB cable that eliminated the need for a USB hub.
The first flash drives were made by M-Systems and distributed in Europe under the "disgo" [1] (http://en.wikipedia.org/wiki/Flash_drive#_note-disgo) brand in sizes of 8 MB, 16 MB, 32 MB, and 64 MB. These were marketed as "a true floppy-killer", and this design was continued up to 256 MB. Asian manufacturers soon started making their own flash drives that were cheaper than the disgo series.
Modern flash drives have USB 2.0 (http://en.wikipedia.org/wiki/USB_2.0) connectivity. However, they do not currently use the full 480 Mbit/s the specification supports due to technical limitations inherent in NAND flash. The fastest drives available now use a dual channel controller, though still fall considerably short of the transfer rate possible from a current generation hard disk, or the maximum high speed USB 2.0 throughput.
Typical overall file transfer speeds are about 3 MBytes/s. The highest current overall file transfer speeds are about 10-25 MByte/s. Older, "full speed" 12 Mbit/s devices are limited to a maximum of about 1 MByte/s.
Flash drives have become iconic as a sort of "fashion statement" [2] (http://en.wikipedia.org/wiki/Flash_drive#_note-fashion), much like the iPod (http://en.wikipedia.org/wiki/IPod)'s white ear bud headphones.[we refer it as 'IT sura']
