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.

ASRock Debuts with X99E-ITX/ac Haswell-E Mainboard

ASRock places itself on record with an offbeat solution – the first ever mini-ITX mainboard for Socket LGA2011-v3 platform. The X99E-ITX/ac is developed for the most efficient Haswell-E CPUs (Intel Core i7-5000 series). The Intel X99 chipset ensures the board’s functionality, though it was limited due to compact dimensions.



ASRock X99E-ITX/ac accommodates two slots for two-channel DDR4 memory modules. Storage subsystem offers four SATA III 6 Gb/sec ports, a single SATA Express, and one Ultra M.2 slot that uses four PCI-e 3.0 x16 lanes. Expansion is supported by one PCI-e 3.0 x16 slot only.


This mainboard comes equipped with mPCIe 3.0 x1 socket as well as a modular unit for Wi-Fi 802.11 ac and Bluetooth network connections. They are accompanied with a pair of gigabit Ethernet controllers from Intel. A set of external interfaces boasts two ultra-new USB 3.1 Type-A ports. Four USB 3.0 ports, a couple of USB 2.0 ports, one eSATA port, and five 3.5 mm mini-jacks for the …

HIS Showcases New Graphics Card with Improved UVD GPU

The line of graphics cards manufactured by HIS has been recently replenished by an alternative Radeon HD 7950 IceQ Boost Clock model. The card takes a modified graphics adapter from AMD and is based on Tahiti PRO chip, developed according to 28 nm technological process. This chip houses 1792 current processors which are designed under an advanced Graphics Core Next architecture.



One of the major technological peculiarities pertained to a new model is the implementation of a unique two-slot IceQ cooler that involves an aluminum heatsink, four copper heat pipes and low-noise powerful fan. As claimed by the manufacturer, the integrated cooling system exceeds the cooler applied in the reference model in terms of heat dissipation power and noise. Hence, noise level produced by IceQ does not exceed the boundary of 28 dB; at the same time, it reduces the GPU temperature at 12 degrees as compared with the reference model.


To continue, Radeon HD 7950 IceQ Boost Clock is based on a …
