DAS Promise Pegasus R4 Review

Data storage units have become an integral part of PC hardware in recent years. Such conjuncture is simply explained by the rising necessity to store huge amounts of information and transfer the data to various devices. NAS and DAS units have been developed with the intention to solve all storage problems, however, the efficiency of their work is much dependent on the interfaces they use for data transfer. USB 2.0 interfaces are unable to cope with voluminous info; the prevalent now USB 3.0 and eSATA interfaces are efficient only for a single winchester. But when it comes to the management of really huge data blocks, there appears a need for a more advanced solution. Promise Technology dares to solve all vital issues by releasing DAS Pegasus R4 with Thunderbolt interface which is notable for the high and stable data transfer speed with the retention of compatibility.

Announcement of video card Gigabyte Radeon HD 7970 Super Overclock

The efforts of Gigabyte engineers culminated in the release of the Radeon HD 7970 Super Overclock, also known as GV-R797SO-3GD. This is a monstrous construction with height of 64 mm (3.5 expansion slots) and a cooling system WindForce 5X. As well as preparing to be released GeForce GTX 680 SOC, the new adapter uses a five high-speed (> 4000 rev / min) fan size of 40 mm, copper evaporation chamber, and five copper heat pipes.



WindForce 5X – is one of the most expensive VGA-coolers, except for models with water blocks and liquid cooling system. It will allow to overclock Gigabyte GV-R797SO-3GD up to frequencies of 1155/7620 MHz. However, neither the temperature nor the noise performance of video card can be considered satisfactory: 85 degrees under load and 91 ° C for overclocking with increased voltage, and 8000 rpm in a heavy-duty (1185 MHz, 1.375 V) explains the situation.


Printed circuit board Radeon HD 7970 SOC is reinforced with five polymer capacitors NEC / …
