Niedawno WDk zaprezentowal nowa rodzinke dyskow (1.6GB/talerz) a tu
kolejna niespodzianka. Po dyskach 11600LA, 23200LA, 34300LA oraz 35100LA

WD Caviar 6.4 GB Hard Drive
The Latest Generation of High-Performance WD Caviar Hard Drives
Western Digital's WD Caviar AC36400 hard drive sets new standards for
storage, performance, and reliability. With a storage capacity of 6.4
gigabytes, this workhorse WD Caviar drive is engineered to handle
today's most storage-intensive desktop, workstation, multi-media, and
internet applications.

Features
* MR Head Technology - Magnetoresistive heads provide separate read
and write elements, allowing optimization of the two functions for
increased areal density and improved performance of the hard drive
* Ultra DMA/33 High-Speed Host Transfers - Doubles the current
transfer rate under local bus environments.
* CacheFlow5TM - Increases performance by adapting read and write
operations on-the-fly and works in conjucntion with the advanced
disk caching capabilities of today's major operating systems.
* S.M.A.R.T. - Assists the user in preventing possible system down
time by warning users of the impending risk of data loss.
* Low Power Consumption - Saves energy, money, and the environment.
* Exceptional Quality - Guaranteed compatibility and automatic
defect management allows easy installation. A three-year warranty
and 350,000 MTBF means years of trouble-free operation.
* Total of Twenty New Features - This latest generation WD Caviar
hard drive includes twenty new robust features, including firmware
enhancements, that were specifically designed for the MR head
implementation and its quality processes.
Using the industry-recognized 3.5-inch, low-profile WD Caviar design,
the AC36400 drive incorporates leading-edge magnetoresistive
technology to meet increasing capacity requirements. Read and write
elements in the MR head are separate in order to optimize read
write capabilities. The read element, composed of a thin-film material
whose resistance changes in the presence of a magnetic field, produces
a strong signal, allowing significant increases in areal densities.
The AC36400 drive supports Mode 4 PIO, Mode 2 [4hDMA and Ultra
DMA/33[4l
Ultra DMA/33 is a high-speed host data transfer feature that transfers
data at 33.3 MB/s - double the current burst transfer rate. This
results in maximum disk performance under PCI local bus
environ[4hment[4l
Western Digital's award-winning WD Caviar hard drives are your best
choice for powerful systems running Windows 95, Windows 3.1x, Windows
NT, OS/2 Warp, Novell NetWare, or Unix operating systems on 486,
Pentium, Pentium Pro, Pentium II, PowerPC, or RISC-based processors.
Western Digital's rugged and reliable WD Caviar hard drives are
designed and manufactured to the highest standards of quality and
reliability. This commitment to quality is demonstrated by Western
Digital's company-wide ISO 9001 certification. Before shipping, every
WD Caviar drive undergoes over 200 rigorous tests to ensure its
functionality and compatibility. So it's not surprising that they have
also set new standards for reliability, are rated at 350,000 hours
Mean Time Between Failure - and are backed by Western Digital's
comprehensive three-year warranty.
