OCZ RevoDrive — NVMe SSD with a speed of work of 2,4 GB / with

1 year ago


The Solid State Drive technology gradually develops. The volume of drives increases, the cost, $/GB gradually decreases, and reliability of such devices increases. On CES 2016 at once several vendors showed the last achievements in this sphere. The OCZ Technology group, part of Toshiba Group Company, at this exhibition showed new model of the drive — RevoDrive 400 NVMe PCI Express SSD.

Performance of the device is rather big. So, OCZ used the NVMe technology for improvement of indicators of reading/record. In the new drive the X4 PCI Express interface by means of which SSD is connected to the motherboard is used.

Elbrus: from the past in the future

1 year ago
Under the proud name "Elbrus" there was a series of supercomputers which was developed by the Soviet scientist Vsevolod Sergeyevich Burtsev (70-80th). These computers entered a number of innovations to the theory of computers, such as a superskalyarnost (processing more than one instruction for one clock period), implementation of the protected programming with hardware data types, parallel processing of several instructions. But their orientation to languages of the high level was the main feature of the Soviet supercomputers. The Soviet-American scientist Vladimir Mstislavovich Pentkovsky participating in development "Elbrus" created a high-level programming language Ale-76.

Except improvement of the sphere of the Soviet computers, the computer became base for creation of 64-bit universal microprocessors "Elbrus 4-C" and the next generation "Elbrus 8-C". They diluted the market of the American vendors of Intel, AMD and IBM. Local development and production of processors it was caused by requirement to find own solutions for the defense industry where use of domestic devices is more desirable.

1 year ago


On Kickstarter the most interesting project — the single-board mini-PC PINE A64 appeared a few weeks ago. His developers consider that this single board computer can be used in the most different spheres, including telecommunications, electronics, educational projects, entertainments.

Despite the small sizes, this quite powerful device, for the class, of course. The quad-core 64-bit ARM A53 processor with a frequency of work of a kernel of 1,2 GHz forms a basis. GPU — MALI-400 MP2 (2 kernels, 500 MHz). Performance of a graphic subsystem is slightly higher, than at original X-Box.

The new line will appear in 2016. Vendors provide a scanty information about new products.

Management system greenhouse microclimate

Beginning of a way


In one solar afternoon, having come to University, I learned that in this semester at me course on circuit engineering. The teacher suggested to make only the explanatory note "how to implement the project" or to learn a dark side of engineering and to create the real device. And as I was already on the 4th course, and having remembered that the only time when I put into practice the skills of the engineer was at the first year (fastened a book shelf to a wall), I decided "to work as handles". After short reflections, I selected the subject "Management System Greenhouse Microclimate". Most likely the choice was influenced by my love to automation of processes, or the fact that I also was engaged in cultivation of cucumbers in greenhouses. But we will long not pull — we begin.

1 year ago


Last year the Samsung corporation provided the first portable SSD disk, Portable SSD T1. Now the South Korean company provided more capacious model, exceeding the previous option in several parameters. At the same time, Portable SSD T3 has and much in common with the predecessor. For example, vertical NAND (V-NAND) memory is here too used thanks to what speeds of reading/record reach an indicator in 450 Mbps.

In spite of the fact that the device is slightly more than predecessor, it still can be placed in a pocket — there are no problems with portability. To t3 it will be available in several modifications, with a capacity of 250 GB, 500 GB, 1 TB and 2 TB.
