Thunderbolt 2. The fastest, most versatile I/O in any desktop. Of any size


Thunderbolt 2 technology in GT4670-TB is phenomenally fast. The two Thunderbolt 2 ports on GT4670-TB features dual 20-Gbps channels for data transfer and that’s up to four times faster than USB 3. But beyond speed, Thunderbolt gives you unprecedented expansion capabilities. You can daisy-chain as many as six Thunderbolt devices to a single port. And since Thunderbolt is based on Display Port technology, Mini Display Port devices like Apple LED Cinema Display can plugs right in, too.


RAID 0 (Speed Mode), RAID 1, RAID 10 and JBOD (Four Independent Volumes) for you to choose according to your needs.


The GT4670-TB has four built-in disk configuration modes: RAID 1 (Safe Mode), RAID 0 (Speed Mode), RAID 10, JBOD (Two Independent Volumes) for you to choose according to your needs.


The RAID 1 function provides fully automatic backup that ensures data security.


RAID 0 functionality increases storage speed and performance.


RAID 10 is a RAID configuration that combines disk mirroring and disk striping to protect data.


JBOD function provides two independent disk data access convenience.



RAID 0 functionality increases storage speed and performance


The new GT4670-TB is equipped with RAID 0 storage mode, which enables user to attain up to 724MB/s read speed with GT4670- TB's Thunderbolt transmission interface. Whether it is used for searching and editing photo galleries, or video editing and synthesis, it promises to deliver a smooth and easy operation.



Removable design, use multiple hard drives flexibly


The  GT4670-TB is a quadruple drive storage enclosure system that supports the latest 3.5" and 2.5" SATA hard drives to deliver high- capacity data storage solutions. Featuring flawless structural design, optimized internal configuration, and a durable aluminum casing to protect your internal drives, the  GT4670-TB is perfect for creative and highly mobile professionals.



Stylish and rugged

The GT4670-TB has a sleek exterior design that’ll never go out of style when placed next to your Mac. It’s also built tough with three millimeter thickness aluminum to shield the enclosed drives durably and to dissipate the heat created by the drives faster for the drives to work comfortably.



Thunderbolt 2


The ultimate all-in-one demands the most advanced I/O technology. Each tiny Thunderbolt port lets you expand the capabilities of your Mac for connecting high performance peripherals, transfer data at high speed, or even daisy-chain multiple devices. And the new iMac with Retina 5K display has Thunderbolt 2 built-in, delivering twice the bandwidth — up to 20 Gbps — for the fastest data transfers.

To help you complete your photography projects


With two ultrafast Thunderbolt 2 ports, you can build a photo studio around MacBook Pro and GT4670-TB. Or take them with you and import thousands of RAW images on location — up to six times faster than on a standard MacBook Pro. Once your photos are on your computer, editing in Aperture is faster and more responsive than before. GT4670-TB's RAID 0 mode lets you quickly browse large image libraries from external storage.So you have instant access to any photo in your library.

Environmentally friendly


GT4670-TB is made from highly recyclable aluminum and it is also free of many harmful toxins which commonly present in the desktop computer manufacturing process.


Advanced power management.

GT4670-TB uses energy-efficient hardware components that work hand in hand with the Mac system to conserve power. It spins down hard drives and activates sleep mode after a period of inactivity.
