Business Wire
TDK Corporation (NYSE:TDK) announces the development and release of
the GBDisk� RA6 series of silicon disk modules with a maximum
storage capacity of 8 GBytes. Production is scheduled to begin in
April 2007. As the storage capacities of NAND Flash memories
increase while their prices fall, silicon disks that combine
multiple memories for use as hard disk drive (HDD) replacements are
attracting considerable attention. Since NAND Flash memories do not
use motors or other moving components, they offer excellent shock
resistance and low power consumption compared to HDDs. Industrial
equipment does not require the large storage capacities of HDDs,
but do have considerably more rigorous demands for concussion
resistance and low power consumption, driving up demand for silicon
disks. The GBDisk� RA6 series meets these demands. The NAND Flash
memory controller, a necessity for silicon disks, is the GBDriver�
RA6, a controller IC developed by TDK that has an established track
record in industrial applications. This enables a high level of
distributed processing when writing data to the memory and maximum
effective use of each Flash memory recording block, enhancing
reliability. In addition, the GBDisk� RA6 modules are the
industry�s first(a) silicon disks that are compatible with SMART
commands, simplifying management of bad memory blocks and making it
possible to forecast the rewritable lifespan so advance warnings
can be issued. The physical size is approximately the same as a
2.5-inch HDD, and the maximum storage capacity is 8 GBytes. In
addition, an HDD interface is embedded, making the transition from
HDDs to silicon disks easy. The devices offer outstanding
concussion resistance and are guaranteed up to 1,500 G during
operation. The main target market is industrial equipment
applications. (a) As of March 8, 2007, according to TDK
investigations. Applications Recording media for industrial
equipment operating systems, file systems, user data, and so on.
Recording media for devices that require low power consumption such
as mobile PCs and devices that must withstand rigorous
environmental conditions (vibration, high altitude, etc.). Main
Features 1. High-Speed Read/Write Write performance of 23 MBytes/s
(equivalent to 150X speed) Read performance of 24 MBytes/s
(equivalent to 160X speed). 2. Outstanding Error Correction and
Recovery Functions Four-symbol (40 bit)/sector ECC function. 3.
Improved Power Interruption Tolerance The GBDisk� RA6 completely
prevents collateral errors that results in the corruption of data
other than the data being written if power is interrupted when
writing data. Production and Sales Plan ? Sample price: US$800/unit
(8 GBytes) ? Production location: Japan ? Production capacity:
10,000 units/month (planned) ? Start of production: April 2007
