Onto a single platter 500G Seagate SV35.5 1TB hard disk monitor

500GB single platter technology to fight a new field: Seagate SV35.5 Series announced the introduction of video surveillance hard drives, the maximum capacity of 1TB. Seagate SV35 Series hard drive specifically for 24 × 7 round-the-clock video surveillance of intensive operation and build into the work cycle, for a particular application to optimize performance and reduce power consumption, improve reliability, mean time between failures more than one million hours, the annual failure rate (AFR) does not exceed 1%, also supports the operation of ATA-7 streaming commands optimize video streaming to the performance and reliability.
The new capacity has SV35.5 Series 1TB, 500GB, 250GB three models "ST31000525SV", "ST3500410SV" and "ST3250311SV", are designed 500GB single platter (SV35.3 1TB four mounted disc), SATA 3Gbps interface , Speed 7200RPM, Cache 32/16/8MB, the stability of data transfer rate of 140MB / s, read seek time 8.5ms, write seek times of 9.5ms, can transfer a maximum of 12 high-definition video streaming or a maximum of 47 Full D1 (704 × 576) video streams.
SV35.5 Series can withstand the highest temperature of 70 ℃, the lowest run-time environment temperature 0 ℃; power consumption typical operation 1TB/500GB Model 7.0W, seeking an average of 10.4W, Standby 1.0W, noise 25dBA, 250GB models of a typical operation of 5.0 W, seeking an average of 8.0W, Standby 1.0W, noise 23dBA, are slightly lower than the existing products. However, the upgrading of a single platter capacity of SV35 does not have any family become thinner thickness, which 1TB/500GB or 26.11 millimeters, 250GB is 20.2 millimeters.

Samsung Show methanol fuel cell for more than 72 hours of life

Samsung's Samsung SDI and Samsung Electronics has a display of military methanol fuel cell. Samsung said this is the best military fuel cells, a 54 percent performance improvement over time can enhance the life 7-8 times.

In the high-tech military equipment is getting higher and higher needs, product portability and durability needs to be considered is the focus of Samsung's new military fuel cell weighs only 3.5 kilograms, enough a normal use of the soldiers three days (72 hours ) above. If similar products life 72 hours, the weight will have to reach 8 kilograms to 10 kilograms.

Samsung next to the fuel cell for notebook computers with foil, which also means that such fuel cells is expected in the future consumer electronics products such as notebook use. However, the volume of the fuel cell, the military is currently only available on computer use, and we ordinary people can not be used with notebook computers.

Intel Larrabee to display at the end of the fastest wafer New Releases

Intel's Larrabee graphics cards since independence has been exposed, it has been the concern of the majority of consumers. In the successful conclusion of the IDF just on, Intel's senior vice president and general manager of Digital Enterprise Group, Mr. Kissinger demonstrates our Larrabee of the wafer.
