Review of Motherboard Gigabyte GA-X79-UD5

The process of PC layout is quite delicate for the majority of people, since it depends on many factors, including requirements to the PC’s performance and customers’ financial possibilities. Motherboard selection is considered to be the most difficult stage in the process because it defines the basic functional characteristics of the computer. It should be stated that motherboards, which are attributed to the top line, show rather good functional but are frequently unaffordable. Quite the contrary, motherboards of the medium line are more preferable for people with average requirements and possibilities. Gigabyte GA-X79-UD5 falls under this category of motherboards and is a perfect alternative for customers with specific requirements and average wages.

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 …
