4-Bay 2.5” SATA III HDD/SSD Hardware RAID Storage

2 Thunderbolt™ 2 ports, Hot-Swappable Drive



Data Transfer Performance and Data Correction 


DX4-TB2 supports 4 pieces of 2.5" HDD/SSD.  You could set 4 of them with RAID X mode which still protects your data from two defective disks at the same time.  It's just like what RAID 1 mode can do for you and even with a better data protection feature than that of RAID 0 mode.  And also, you could get the same data transfer rate as what RAID 0 provide you.  DX4-TB2 not only provides you an excellent data protection but also a good data transfer performance.



The Special Features:


1. Thunderbolt 2.0 brings you an extreme high data transfer speed.


2. Transmission performance than the USB 3.1 to be about 2 times faster.


3. Raid X features provide the data protection and can be meantime error tolerance for each 1 HDD on RAID 1. 


4. Its Background REBUILDING feature lets you keep a stable data transfer efficient even though it's at REBUILDING WORKS.


5. Double Tray Lock designs helps reducing the DEGRADED RAID happening from extracting HDD/SSD Trays accidently! 


Thunderbolt 2.0 brings you an extreme high data transfer speed
DX4-TB2 supports Thunderbolt 2.0 (TB2) interface for an extreme high data transfer speed.  And both of the two TB2 ports are equipped with up to 20Gb/s data transfer rate which is 4 times faster than USB3.0 ,2 times faster than USB3.1 and even 3+ times than SATA III interface.  You could definitely use it to play your 4K high-resolution films with no any lagging hassle.  Thunderbolt 2.0 interface not only brings you this high data transfer rate advantage, it also let you chain maximum up to 6 products (or other compatible storage products).

Transmission performance than the USB 3.1 to be about 2 times faster

Raid X features provide the data protection and can be meantime error tolerance for each 1 HDD on RAID 1 



DX4-TB2 could still protect your data while there are two defective HDDs/SSDs at the same time just like what RAID 1 gives you.  And also, its data transfer performance is equivalent to what RAID 0 gives you too.  


Because of these two excellent features, the RAID 1 grade data protection and RAID 0 grade data transfer performance, you, as the CEO of a small entity (or enterprise), could definitely rely on it for your daily MIS use. 

Even though it's in REBUILDING WORK, DX4-TB2 still keeps the same data transfer rate

DX4-TB2's very special REBUILDING WORK keeps the same data transfer DX4-TB2's three independent RAID X sets helps providing the same data transfer performance even though one of them is defect.


Its new Tray Lock design to help preventing improper extracting Tray


According to the strict restriction at RAID, any improper work to extract HDD/SSD may cause a serious damage to your data.  And DX4-TB2's new Tray Lock design is to protect any improper extraction at HDD/SSD and then help protecting your valuable data.




Its excellent heat dissipation to prolong the HDD life cycle


DX4-TB2's two 4 cm silent fan helps dissipating out the heat generated from HDDs/SSDs efficiently and always keep them with low working environment which helps their life cycle.

Environmentally friendly
DX4-TB2 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.
DX4-TB2 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.


Thunderbolt 2 With DX4-TB2 Stylish and rugged

The DX4-TB2 has a sleek exterior design that’ll never go out of style when placed next to your Mac. It’s also built tough with thickness aluminum to shield the enclosed drives durably and to dissipate the heat created by the drives faster for the drives to work comfortably.

To help you complete your photography projects
With two ultrafast Thunderbolt 2 ports, you can build a photo studio around iMac and DX4-TB2. Or take them with you and import thousands of RAW images on location. Once your photos are on your computer, editing in Aperture is faster and more responsive than before.
