WD Prepares Voluminous Re+ HDDs for Data Centers

Western Digital announces a new high-capacity 3.5-inch HDD for data centers. The WD Re+ will be available in versions of up to 6 TB. All of them are designed with power-saving ideas in mind; hence, their maximal power consumption index does not go above 6 W. The new-comer employs five-platter architecture and SATA 6 Gb/sec interface that guarantees the maximal efficiency level. Moreover, its MTBF index approximates 1.2 million hours on average workload index of 550 TB per year.

The WD Re+ is distinguished by the following advantages:

— the incorporation of dual actuator positioning system that improves the drive’s working efficiency;

— the implementation of RAFF technology that monitors HDD parameters in real time and compensates for the linear and angular vibration;

— the employment of StableTrac technology that reduces vibrations and stabilizes drive platters;

— the usage of TLER technology that prevents latencies or an abrupt destruction of RAID … …

Welcome In New LPDDR4 Memory Chips from Samsung

Samsung settles down to a large-scale production of LPDDR4 mobile memory chips. Elaborated according to 20 nm technological norms, the new-comers boast the integration of an advanced technology that ensures 8 Gb crystal density and twice the performance compared with LPDDR3 chips. Currently, the company produces models of 2 GB and 3 GB capacity, however in early 2015 it will set to the development of 4 GB solutions.

New LPDDR4 memory modules are targeting various mobile devices with thirst for lightning-fast data transfer speed. The latter index might accelerate up to 3200 Mb/sec; this will allow employing chips for the implementation of resource-intensive tasks, such as recording and playback of high-resolution video or serial filming.

Samsung developers claim that 2 GB LPDDR4 DRAM is 40% more power-efficient than counterparts with 4 Gb crystal density. This became possible due to the adopting of low-voltage swing-terminated logic for I/O signaling. As a result, the …

PSU Seasonic X-1250 SS-1250XM Review

Power supply unit Seasonic X-1250 is a senior product of X series that includes units from 400W to 1250W power. The two junior models are absolutely passive, while all other models feature hybrid cooling schedule. This implies that on conditions of little loading, the integrated fan stops its operation; and vice versa, when the loading is increasing, the fan's operation is more intense. PSU X-1250 is quite powerful to serve the needs of high-performance systems that require stable and efficient power to all key components.

Basic Features

Power supply unit Seasonic X-1250 is delivered in a spacious cardbox which contains a set of cables for the connection of PC components. The unit is housed in a dull black casing with stamped yellowish grid. The whole construction is 190 mm in length (+20 mm for cable connectors), so it won't suit compact-sized PC chassis. All basic specifications are indicated on the casing: the availability of +12VDC line that demonstrates 1248W power at …
