IBM Deskstar 5 3.5-inch 4.3 and 6.4 GB
low profile ATA disk drives
High-capacity storage for today's most advanced desktop applications
Deskstar wins PC Computing's 'Best' award
Highlights
Enhanced capacity
Capacities of 1.62 GB per platter meet the needs of a broad range of
today's higher-capacity desktop applications. This superior capacity
is made possible through today's advanced processors, enhanced video
compression technology and emerging workstation-like applications for
Windows NT. *
Superior performance
With an average seek time of 9.5 ms and sustained data rate of 5.4
MB/sec. (min.), this solution provides the enhanced performance
required by today's data-intensive software applications, the latest
professional-quality video and sound applications, large databases,
and collaborative processing such as Lotus Notes.
Increased data performance
PRML digital data channel capability delivers increased media-to-
buffer and buffer transfer rates, enhancing data performance.
Data protection
S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology)
protocol support protects data availability and helps alert a system
of impending drive failure.
Leading drive technology
The Deskstar 5 achieves it's enhanced capacity and performance by
taking advantage of IBM's development and implementation experience
in advanced disk drive technologies. These technologies include
Magneto-Resistive (MR) heads, No-ID sector formatting and the PRML
digital channel.
MR heads offer increased areal density, reducing the number of disks
and heads required for a given capacity. No-ID sector formatting
further increases storage capacity by eliminating the overhead caused
by the duplicate storage of each data sector's ID field onto the disk,
creating more available disk space for customer data. The PRML
digital channel implemented now on IBM's newest desktop drives such as
the Deskstar 5 allows for higher areal densities, significantly
enhancing the drive's overall performance.
The combination of these three advanced technologies allows the
Deskstar 5 drive to achieve its high 1.62 GB per platter capacity,
providing exceptional disk drive capacities for performance desktop,
small and home office PCs.
Interface
The Deskstar 5 has a Fast ATA-3 interface and an AT interface transfer
rate of 16.6 MB/sec. enabled by using PIO Mode-4, DMA Mode-2 and 33.3
MB/sec. made possible by using Ultra DMA/33, ensuring optimum data
performance. The Deskstar 5 supports both Logical Block Address (LBA)
and extended Cylinder Head Sector (CHS) addressing modes.
IBM quality and service
IBM drives are backed by an array of technical support and services,
including
customer support
, qualification support and integration
assistance. This comprehensive support package is designed to ensure
that IBM customers can continue to develop and manufacture high-
quality, cost-effective systems.
