Thunderbolt 2 brings you an extreme high data transfer speed

 

SR4-TB2 supports Thunderbolt 2.0 (TB2) interface for an extreme high data transfer speed.  And both of the two TB2 ports are equiped with a up to 20Gb/s data transfer rate which is 4 times faster than USB3.0 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.  TB2 interface not only brings you this high data transfer rate advantage, it also let you chain maximum up to another 5 more SR4-TB2 products (or other compatible stroage products).

Faster data transfer speed

RAID 0 mode to help an efficiency

 

SR4-TB2 provides RAID 0 mode, and pluses its Thunderbolt 2.0 interface protocol, it really gives you an excellent data transfer performance up to 1300MB/s.  It helps your work smoothly on heavy duty video or photos editing works in your Post-production studio.

RAID 5 mode provides highest data parity function ensure your data security

 

RAID 5 mode provides both of the read-&-write efficiency and the data protection features for your daily works.  Under RAID 5 mode, SR4-TB2 would need at least 3 or more HDDs to start working.  And if anyone of your HDDs is defect, your SR4-TB2 would still work fine for you, but just with no more data protection feature.  Comparing to RAID 0 and RAID 1 modes, it's no doubt that RAID 5 is your best choice.

RAID 6 mode, double security is an even better solution in enterprise

 

 

To you, an Enterprise MIS supervisor, the data protection feature would be your first priority to choose your storage product.  Comparing to RAID 5, RAID 6 provides you a way better data protection level.  Under RAID 6 mode, SR4-TB2 would need at least 4 HDDs to start working.  RAID 6 mode provides you the even better data protection than that of RAID 5's from its extremely ZERO Possibility that two HDDs become defect at the same time!  SR4-TB2 still works perfect even though two of the whole HDDs are defect at the same time which won't happen at all!

 

Mechanism

 

A New Design Tray Lock to provide data damage from improper HDD extraction

 

As you know, every RAID mode has its restriction to extract HDD out from every storage enclosure.  And SR4-TB2's new Tray Lock will protect you from your improper HDD extraction accidently!  Without its Lock Key, it's some hard for you to extract any HDD out! It is a best choice for the people on the go usage. 

 

 

 

 

To support SGPIO feature (Serial General Purpose Input & Output)

 

SR4-TB2 provides the SGPIO (Serial General Purpose Input & Output) features.   The SGPIO feature detects the following system failure symptoms by different LED signal, user is easily to find out which HDD(s) defect to ensure SR4-TB2 running smoothly.

MCU feature to provide you in-chassis temperature control

 

SR4-TB2 is also designed with the MCU feature which monitors and helps improving its in-chassis system temperature.  While the system tempeature rises up to 50 degree-C (118 degree-F), MCU will bump up the 8 cm fans with full speed; and once system tempeature goes down to 45 degree-C (109 degree-F), you could manually adjust fan switch on the rear, MCU would reduce the fan speed down to a half speed for a better green user environment from a less fan noise and lower power consumption.

 

 

 

 

The built-in power supply unit

 

SR4-TB2 uses conform with safety regulation certified 200W power supply unit which provides a stable and high efficient power output and definitely satisfies the big power consumption from all 4 HDDs.

 

 

 

Rigid mechnical structure with two 8 cm quiet fans to get rid of the heat efficiently

 

SR4-TB2 is designed with a rigid mechnical struture and covered by a high finishing quality aluminum chassis.  It's also designed with 8 cm large quiet fans to help getting rid of heat efficiently!

Application
