Product Features
Serial ATA (SATA)
— Serial ATA (SATA) is the next generation bus interface for
2.5-inch hard drives. It is designed to replace Parallel ATA, and has many advantages including
increased transfer rate, improved signal integrity, enhanced data protection, and hot plug support.
Perpendicular Magnetic Recording (PMR - Writer)
— With PMR technology the
magnetization of each data bit is aligned vertically to the spinning disk, rather than longitudinally
as has been the case in hard drive technology for decades. This enables more data on a given disk
than is possible with conventional longitudinal recording, and provides a platform for future
expansion of hard drive densities.
Reduced Power Spinup (RPS)
— WD’s optimized start up feature specifically designed for
the external hard drive and Consumer Electronics (CE) market. Specific focus for RPS is to
minimize the duration and magnitude of the peak power consumption from the hard drive.
System-on-Chip
- The System-on-Chip (SOC) is the foundation for WD's next generation
electronics and firmware architecture. The native SATA SOC lowers component count by
integrating a hard disk controller, high performance processor, high speed execution SRAM, and
read channel in a 128-pin package.
S.M.A.R.T. Command Transport (SCT)
— The SCT Command Transport feature set
provides a method for a host to send commands and data to a device and for a device to send data
and status to a host using log pages.
Reliability Features Set-Data Lifeguard
™ — Representing WD's ongoing commitment
to data protection, Data Lifeguard includes features that enhance the drive’s ability to prevent
data loss. Data Lifeguard data protection utilities include thermal management, an environmental
protection system, and embedded error detection and repair features that automatically detect,
isolate, and repair problem areas that may develop over the extended use of the hard drive. With
these enhanced data reliability features, the drive can perform more accurate monitoring, error
repair, and deliver exceptional data security.
Hot Plug Support
— SATA supports hot plugging (also known as “hot swapping”), the ability
to swap out a failed hard drive without having to power down the system or reboot. This
capability contributes to both data availability and serviceability without any associated downtime,
making it a critical feature for extending SATA into enterprise applications.
Active LED Status
— These drives support external LED requirements. It provides an activity
LED output which is ON during command execution and OFF otherwise.
Fluid Dynamic Bearings (FDB)
— Bearing design that incorporates a layer of high-viscosity
lubricant instead of ball bearings in the hard drive spindle motor. As an alternative to conventional
ball bearing technology, FDB designs provide increased non-operational shock resistance, speed
control, and improved acoustics.
Staggered Spin-Up
— Native SATA feature that allows the system to control whether the
drive will spin up immediately or wait until the interface is fully ready.
