The Forthcoming Switch to 5 mm HDD Models

Nowadays HDD segment is represented by various products from various companies. However, with the development and release of ultrabooks, manufacturers directed their production to the hybrid-type drives. This resulted in the predominance of hybrid solutions in the market.



Recently Itel has advanced a motion to digress somehow from the production of hybrid drives and switch to the decrease of traditional HDDs dimensions to 5 mm in casing depth. According to the company's assumptions, such change could moderate the price for drives and provide the necessary volume capacity for ultrabooks.


Some manufacturers have already directed a part of their technological powers to the design of HDDs with 5 mm casings. Nevertheless, there appeared a couple of obstacles on their way: the necessity to stabilize data reading and writing activities, and increase of costs spent on drives' production. This will result in the rise of end price.

Plextor Debuts with M.2 6G Solid-State Drive

Plextor, an award-winning Japanese SSD designer, launches its another M.2 solution, codenamed 6G. This drive features 42 mm length only, fulfilling space requirements of small-sized but high-performance cases. The new-comer is available in two capacity variations: 64 GB (PX-64M6G-2242) and 128 GB (PX-128M6G-2242). Their retail price makes up $50 and $90 respectively.



Both Plextor M.2 6G solid-state drives come with PCI Express 2.0 interface. They are based on Marvell 88SS9188 controller and 19 nm MLC NAND flash-memory with Toggle interface (by Toshiba). The models support TRIM and NCQ technologies as well as DEVSLP power-efficient mode that reduces power consumption to 0.2 mW.


As far as speed characteristics are concerned, M.2 6G accelerate up to 520 Mb/sec on sequential Read operations; sequential Write index depends on the model: 160 Mb/sec for 64 GB model and 210 Mb/sec for 128 GB one. At the same time, random Read/Write operational index (4K blocks) makes up …

Modular Power Supply 650W Chieftec A80

Evaluating the effectiveness of modern computer power supplies, the most attention is paid to their coefficient of performance (COP) at a given load — usually means of 20%, 50% and 100%. At the same time, not less important requirement, established by standard 80PLUS should be considered. That means — the preservation of this level of performance for all occurring in the world supply voltage variations, that is in the range of 100-240 V.



The standard rules of 80PLUS at different levels (Basic, Bronze, Silver, Gold, Platinum, etc.) are performed for two voltage 115 V and 230 V. In both cases, the normalized PS should show the efficiency of not less than specified for each category level. Not usual power supply CTG-650C model of the new A-80 series from the Chieftec company is interesting in that it has officially claimed efficiency of 85% or more, but only for nets 220-240 V.


As the advantages of such solution can immediately be noted a lower price, due to less stringent …
