HGST Announces Corporate-Class Ultrastar C10K1800 Hard Drives

Despite the emergence of ultra-fast and voluminous SSD devices, data processing centers still require classical storage solutions. Hence, HGST, an affiliate company of Western Digital, decided to comply with the corporate demands by introducing budgetary hard drives entitled Ultrastar C10K1800. The new-comers are targeting exactly DPC-systems which are in need of high performance combined with fail-safe behavior.

HGST Ultrastar C10K1800 drives feature 2.5-inch form-factor and come in diverse capacity variations (from 300 GB to 1.8 TB). The models employ SAS interface with 12 Gb/sec throughput. It should be noted that designers involved the minimal amount of plates on the maximal possible tape density. The latter are thought to rotate with 10.520 RPM.

The implementation of only few plates provides for the reduction of power consumption; this is supposed to be a great benefit since the drives are estimated for a durable 24/7 operation. Thus, an average power consumption …

Lian Li PC-10N: Chassis with an Extraordinary Motherboard Localization

Lian Li, a well-known manufacturer of PC cases, has officially introduced its newest chassis codenamed PC-10N. The model is designed in a popular mid-tower form-factor and is ready to accommodate motherboards of ATX, mini-ITX and micro-ATX standard. The chassis differentiates itself by an unusual motherboard localization: instead of conventional tray, the layout stipulates dedicated strips that fix the board. This was done with the aim to provide for a better airflow and to facilitate cable management process. Besides, absence of the tray makes the case much lighter.

Lian Li PC-10N is delivered in two color samples: silver (PC-10NA) and black (PC-10NB). Internal framework allows for the assembling of quite powerful PC systems. It might house rather high CPU coolers (up to 155 mm), rather lengthy expansion cards (up to 300 mm), and ATX-compatible power supply units of up to 300 mm in length. There is a possibility of removing HDD bay to free space for even more lengthy adapters …

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 …
