CacheFlow
™ —WD’s unique, multi-generation caching algorithm evaluates the way data
is read from and written to the drive and adapts “on-the-fly” to the optimum read and write
caching methods. CacheFlow minimizes disk seek operations and overheads due to rota-
tional latency. CacheFlow supports sequential and random write cache. With write cache
and other CacheFlow features, the user can cache both read and write data. The cache
can hold multiple writes and collectively write them to the hard drive.
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 Management
— WD SATA drives support the ATA and Serial ATA power
management command set, allowing the host to reduce the power consumption of the drive by
issuing a variety of power management commands.
Automatic Defect Retirement
— If the WD SATA drive detects a defective sector while
reading, writing, or performing offline data collection, it automatically relocates the sector without
end-user intervention.
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
— WD SATA drives support 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 also supported.
Automatic Acoustic Management (AAM)
— The drive supports the Automatic Acoustic
Management feature. This feature allows the host to select the acoustic level of the hard drive.
