The latest technology for the fastest writing

1.Speeds up writing "DRAM Cache"

DRAM cache is a technology increases processing speed by using data
sent from the PC to the HDD
using DRAM in write processing of data sent from the PC to the drive
The HD-GDU3's hight-capacity DRAM cache enables you to write data
even faster.

2.More efficient data transrers "TurboPC EX"

Using "TurboPC EX"Speed Mode increases efficiency in transferring data
from the computer to the hard disk drive,thereby reducing the time needed in copying the data.

3.10times faster than USB 2.0 "USB 3.0 interface"

3.10times faster than USB 2.0
"USB 3.0 interface"
The HD-GDU3'S USB 3.0 interface features a maximum transfer speed (standard value) of 5 Gbps. This is more than ten times faster than the 480 Mbps transfer rate available with conventional USB 2.0

Software suite for easier,more enjoyable computer use

The HD-GDU3 includes "Buffalo Tools,"a feature-rich suite of software that makes using the computer easier and more enjoyable.In addition to increasing hard disk storage capacity and allowing you to save,copy,and back up data faster,this comprehensive package also featuress useful software for reducing energy consumption,formatting the disk,and more.

●Includes "TurboPC EX" speed-enhancing software
TurboPC EX optimizes transfer speeds by using the computer's RAM as a cache.In copying and transfeming,data is read and written in larger chunks,increasing intemal processing efficiency for faster copying.

●Reduces energy use,easy on the budget
●Reduces energy use,easy on the budget
This tool switches the drive to "Power Save Mode" and putting the hard drive to sleep after a specified period of drive inactivity. Compared to ordinary idling,"Power Save Mode" provides a vast cut in power consumption

●Shortens backup times
This software uses the same process as TurboCopy to speed
up data transers in backups and reduce the time in waiting for backups to finish.You can also schedule automatic backups at specified times,making this a hassle-free process.

●Turns memory into a high-speed drive
●Turns memory into a high-speed drive
This software utility lets you use a portion of your computer's memory(RAM) as a drive(RAM disk).RAM disks work much faster than usual storage media,handling data with ease.This is optimal for working with files that you use frequently.

●Easy formatting
This software allows you to format hard disks and other drives simply and easily.

Power Save Mode reduces power energy consumption

This unit includes the energy-saving "eco Manager" software.When inactive for a specified period of time,the drive automatically switches to "Power Save Mode," reducing power consumption. This HDD is good both for the environment and the family budget.

Nearly silent fanless design

The fanless,vibration-proof design ensures completely quiet operation.Use this drive without concern,even in locations where machine noises are easily noticed.

*Adding the optional "OP-FAN-ALEM" cooling fan circulates the air flow within the HDD,making this an effective way to reduce the unit's temperature.
