Lifting the Veil from USB Type-C Bus

Since the launch in 1995, Universal Serial Bus (USB) has proved itself as the most successful ever computing interface. Nowadays tens of billions of electronic devices are connected together due to it. It goes without saying that this bus has outlived a few modifications, each distinguished by higher speed and reliability. Thus, today the community is able to revel in a completely new modification – USB Type-C – that forecasts a lot privileges of connectivity process. Let’s see what users will get with a new bus.



Layout and Connectivity


In physical terms, Type-C is a bit larger than USB 2.0 Micro-B but a bit tinier than binary USB 3.0 Micro-B, featuring 8.34x2.56 mm. Such dimensions enable its connection to the devices of any type, including the thinnest smartphones/tablets. The oval-shaped socket houses 24 contact outputs (to compare: USB 3.0 sockets feature only 9 outputs).


The most outstanding physical peculiarity of Type-C is a symmetric connector that …

Minimalism in new Lian-Li PC-Q25 hull

The market of computer components is growing rapidly. The developers of processors integrate in them elements of system logic, graphics core and other components that were recently placed on the motherboard in the form of individual chips. Motherboard manufacturers have begun to integrate their products with network and sound chips even earlier. All this allows making motherboards, and as a result, systems based on them more compact. The company Lian-Li have understood this tendency and provided the market with the entire line of compact hull designed for motherboard size Mini-ITX.



Consider the model Lian-Li PC-Q25:

— Hull Type — Mini-Tower;

— Dimensions in mm — 280 (H) x 199 (W) x 366 (D);

— Material – Aluminium;

— Weight, kg — 3.1;

— Color: Black / White;

— Form Factor — Mini-ITX/Mini-DTX;

— Devices 3.5 "/ 2.5" internal — 7/3;

— Supported number of expansion cards – 2;

— Fans 1x 140mm, 1x 120mm;

I-O Data Introduces New SSDN-3V to the Home Market

I-O Data, a well-known Japanese developer of top-tier peripheral and interface products, is going to introduce its new SSD series, codenamed SSDN-3V. The newbies will become available in the home market already at the end of the current month. The series involves three models of 60 GB (SSDN-3V60), 120 GB(SSDN-3V120), and 240 GB (SSDN-3V240) capacities. All the models are thought to support SATA 6 Gb/sec interface.



Solid-state drives from I-O Data are based on SandForce/LSI SF-2281 controller and employ NAND flash-memory, designed under 24 nm technological process. SSDs feature 7 mm case depth, but the availability of a dedicated adapter promotes for their installation into a standard 9.5 mm drive bay.


In regard to performance, SSDN-V3 drives offer up to 306 MB/sec speed on consecutive reading operations and up to 186 MB/sec on consecutive writing operations.


Moreover, the manufacturer will deliver the products in a package with a special adapter for the connection …
