HD501LJ Features Image 1

Serial ATA

SATA is a computer bus technology primarily designed for transfer of data to and from HDDs and optical drives.
It uses only 4 signal-lines, allowing for much more compact cables compared to PATA.

device initiated power management

When there are no commands on the HDD, this feature automatically switches on power saving mode and cuts down on electricity through the SATA cable.
It can effectively reduce power consumption.

high speed dual DSP(Digital Signal Processor) based architecture

High speed dual DSP in the main controller IC enhance the performance and speed of the HDD.

ATA automatic acoustic mangement feature set

Automatic acoustic management feature set is an optional feature set that allows the host to select an acoustic management level.

ATA streaming feature(optional)

ATA streaming feature supports command set for AV data that stream error logging to reduce time delays for system error processing and handle stream errors to enable full error recovery.


SilentSeek is designed to minimize the mechanical excitation generated by any resonance, virtually eliminating the source of seek acoustic noise.

SATA Native Command Queuing(NCQ) feature set

SATA NCQ is created to improve the HDD performance by re-ordering the commands sent by the computer to the HDD.

enable/disable staggered spin-up

Staggered spin-up of HDD is not confined solely to mobile drives, and is a feature of many multi-drive systems using RAID.
This feature allows not only greater reliability, but also the system to avoid power surges if all of the HDDs spin up simultaneously during system power up (in a multi-drive environment).

ATA S.M.A.R.T compliant

ATA S.M.A.R.T compliant is designed hard disk drive to check the reliability itself and directly transfer to host.

ATA 48-bit address feature

ATA 48-bit address feature is a technology which extends the capacity of IDE ATA/ATAPI devices beyond this limit of 137.4 GB, supporting 48 bit LBA.

ATA device configuration overlay feature

ATA device configuration overlay feature set allows a utility program to modify some of the optional commands, modes, and features sets that a device reports as supported in identifying device command response as well as the capacity reported.


ImpacGuard prevents an HDD disc from vibrating when not assisted by the helping head media, which is parked in the landing zone.
