Solid state disks hard disks to move the body

As an alternative to conventional hard drives therefore move more recently flash memory in the attentional focus. Flash memory, for example, used in USB sticks, MP3 players, mobile phones and digital cameras,HP batteryand so on . You have two crucial advantages over traditional ferro-magnetic storage: they are due to the low access times faster than conventional hard drives, since it eliminates the time consuming placement of the read-write head. Also reduces the operating noise, as there are no moving parts. And for the same reason, flash memory are much more secure than magnetic storage, as the dreaded head crash, so the placement of the read-write heads on the platters, here are impossible. And average access time in the "zero point field" are also more than impressive.

Moreover, need flash memory for read and write far less power from Dell latitude d500 battery than traditional hard drives. Flash memory drives - so-called Solid State Disks (SSD) - will need about 0.5 watts under load, while classical disks the power failure about four times higher (see above). At rest in flash memory hard drives even simply sensational 0.1 watts can be achieved. These values are achieved mainly because in these media are no moving parts such as electric motors are used. During the operation also creates much less waste heat stromzehrende.

Flash memory directly on the motherboard

In practice, flash memory but are not only used as a USB flash drive or hard disk replacement. As an example, at this point Intel's specially developed for the Merom processor and the Crestline chipset, "Robson" technology mentioned. Here is a flash memory integrated directly onto the motherboard and uses it in addition to memory for faster access to data and on Save electricity of Dell xps m1210 battery , because the disk is not activated. but we follow the views of market researchers, will be equipped in the near future the majority of all notebooks with flash memory drives - then no longer necessary Robson.

Thanks to energy efficient components, the entire system produces less waste heat, which must be dissipated. Must work, for example, the fan less often or can perform their work with a lower speed - and that ultimately saves power and reduces the way, the operating noise of the notebook.

Displays: reduce the power consumption of LEDs Better

While in 2003 the average power consumption of notebook displays still was 4.5 watts,like Dell vostro 1510 battery , have modern notebook displays now an average power consumption under 3 watts. The reduction appears to be low, but on average it may indicate up to 60 minutes longer battery life.

Samsung plans for the second half of the introduction of LC displays in which the backlight is provided by white LEDs. This is the power consumption of 2 watts are reduced and also a sensational contrast ratio of 10,000:1 be achieved. In the future, the manufacturer wants to go even further and introduce an AMOLED display (Active Matrix Organic Light Emitting Diode). A screen with this technology is extremely thin, very bright lights and consumes less power of Dell vostro 1400 battery. In addition to AMOLED displays have an extremely high contrast of 1,000,000:1.
