Advanced Format (AF) Technology adopted by WD and other drive manufacturers
as one of multiple ways to continue growing hard drive capacities. AF is a more
efficient media format that enables increased areal densities.
Native Command Queuing (NCQ) — Performance of a random I/O workload can be
improved through intelligent re-ordering of the I/O requests so they read/write to
and from the nearest available sectors and minimize the need for additional disk
revolutions or head actuator movement. This improvement can be achieved though
Native Command Queuing (NCQ), which is supported by these hard drives.
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.
World Wide Name (WWN) — The World Wide Name (WWN) defined in ATA
Command Set (ACS) is a modification of the IEEE extended unique identifier 64 bit
standard (EUI-64) and is comprised of three major components: naming authority,
organizationally unique identifier (OUI) and serial number.
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 — The drive supports 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.
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.
48-bit Logical Block Addressing (LBA) — WD SATA drives support both 48-bit and
28-bit LBA and CHS-based addressing. LBA is included in advanced BIOS and
operating system device drivers and ensures high capacity disk integration.
Power ManagementThe drive supports the ATA and SATA power management
command set, allowing the host to reduce the power consumption of the drive by
issuing a variety of power management commands.
Self-Monitoring, Analysis, and Reporting Technology (S.M.A.R.T.) — S.M.A.R.T.
enables a drive’s internal status to be monitored through diagnostic commands at the
host level and during offline activities. S.M.A.R.T. devices employ data analysis
algorithms that are used to predict the likelihood of some near-term degradation or
fault conditions. When used with a S.M.A.R.T. application, the drive can alert the host
system of a negative reliability status condition. The host system can then warn the
user of the impending risk of data loss and recommend an appropriate action.
ATA Security — The drive supports the ATA Security Mode Feature set. The ATA
Security Mode feature set allows the user to create a device lock password that
prevents unauthorized hard disk access even if the drive is removed from the host
computer. The correct password must be supplied to the hard drive in order to
access user data. Both the User and Master Password features are supported, along
with the High and Maximum security modes. The Master Password Revision code is
