The advanced-technology,
high-performance SCSI drive with 9.1 GB of formatted
capacity. With the rapid growth of
enterprise-wide networks and robust applications like
multimedia production and CAD/CAM, today's high-end
computer systems literally devour storage capacity. To
meet the demands of these high-end work stations, servers
and mid-range computers, Fujitsu created the M2949S, the
highest performance and capacity 3.5-inch drive in its
class. The M2949 blends advanced technologies and proven
engineering expertise in a compact, power saving package
to deliver a massive 9.1 GB of formatted storage, seek
times as low as 10.0 ms, internal transfer rates of up to
14.0 megabytes per second and industry-leading MTBF
ratings.
Uncommon Performance / Maximum Capacity
The M2949S combines advanced magneto-resistive (MR)
head technology and digital read channel (PR4ML)
electronics along with advanced caching strategies to
deliver the ultimate in reliable data storage performance
and capacity. Rotational speeds of 7,200 RPM, low 4.17 ms
latency, fast seek times, rapid 10/20/40 MB/s interface
burst transfer rates, spindle synchronisation, and a host
of other performance-driven features make the M2949S a
mass-storage leader.
Advanced Technology
Fujitsu was one of the first disk drive makers to
consistently deliver volume production of reliable MR
head technology and PR4ML electronics to the mass storage
market. A world-wide technology leader, Fujitsu combines
more than 25 years' experience and unparalleled expertise
in computer and peripheral design and manufacture to
deliver leading-edge data storage solutions.
Outstanding Reliability
In the computing world, Fujitsu has long been
recognised as a leader in quality and reliability. The
M2949 clearly demonstrates this long-held commitment, as
evidenced by the drive's industry-leading MTBF and
five-year warranty. When the application demands
leading-edge performance and exceptional capacity in a
power-saving 3.5-inch form factor, you can rely on
Fujitsu's advanced M2949 hard disk drive.
