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.

DAS Promise Pegasus R4 series does not differ so much in design terms from other …

Scythe Mugen 5 Is a Powerful CPU Cooler Up to 160 mm High

A new sample – Scythe Mugen 5 (SCMG-5000) – has come into line with the famous Scythe Mugen series. Its asymmetric Tower construction enhances compatibility with long RAM modules. The dimensions of the unit are 154.5 х 130 х 110 mm, and the weight equals to 890 g, which widens the range of chassis able to hold it.



Scythe Mugen 5 possesses a nickel-plated copper base frame, six nickel-plated copper heat pipes, an aluminum heatsink and a 120 mm Scythe Kaze Flex 120 PWM axial flow fan. It is constructed with refined hydrodynamic bearings (Sealed Precision FDB) with the specified life span of 120,000 hours. The rotary speed of 300–1,200 rpm is able to create an airflow in the volume of 16.6–51.17 CFM (28.2–86.93 m3/hr). The static pressure is estimated to be 0.076–1.05 mm H2O, and the noise level lies in the range of 4–24.9 dBA. One can optionally install another analogous fan on the other side.


The brand Hyper Precision Mounting System II makes it possible to …

HGST Announces Corporate-Class Ultrastar C10K1800 Hard Drives

Despite the emergence of ultra-fast and voluminous SSD devices, data processing centers still require classical storage solutions. Hence, HGST, an affiliate company of Western Digital, decided to comply with the corporate demands by introducing budgetary hard drives entitled Ultrastar C10K1800. The new-comers are targeting exactly DPC-systems which are in need of high performance combined with fail-safe behavior.



HGST Ultrastar C10K1800 drives feature 2.5-inch form-factor and come in diverse capacity variations (from 300 GB to 1.8 TB). The models employ SAS interface with 12 Gb/sec throughput. It should be noted that designers involved the minimal amount of plates on the maximal possible tape density. The latter are thought to rotate with 10.520 RPM.


The implementation of only few plates provides for the reduction of power consumption; this is supposed to be a great benefit since the drives are estimated for a durable 24/7 operation. Thus, an average power consumption …
