Ultrastar 15K300 –
the technical benefits
The Ultrastar 15K300 has been
designed to meet the demands
of speed-hungry enterprise
environments involving online
transaction processing, intensive
data analysis and multi-user
applications. Applications
which require fast, random data
access – whether in storage or
server applications.
The Ultrastar 15K300 delivers
24% better IOPS performance
than a standard 10K hard drive.
This improvement means that the
15K drive can meet throughput
requirements with fewer drives
than its 10K equivalent (see
Figure 1.0 below).
Beyond speed
As well as providing blistering
speed, the 3.5 inch Ultrastar
15K300 offers:
n 73GB, 147GB and 300GB
capacities for configuration
flexibility
n Rotational Vibration Safeguard
(RVS), ensuring performance in
multi-drive systems
n 16MB cache buffer, optimizing
response times and minimizing
overhead command
n Ultra320 SCSI, 3Gb/s Serial-
Attached CSI (SAS) and 4Gb/s
Fibre Channel interfaces
n Workload detector technology
to maximise performance in
RAID environments
n Thermal Fly-height Control
(TFC) and Adaptive formatting
for improved reliability and
performance
n TMR head technology,
producing highly reliable high
density storage
n Head load/unload ramp to
minimize drive failures
n 5 year warranty, so you have
full peace of mind
