SSD SanDisk has expanded its portfolio with a 2.5-inch model with a capacity of 60 gigabytes and 120 gigabytes. The drives feature a G3 dominate the Windows 7 supported TRIM command, which ensures a consistently high level of readiness to perform a Solid State Drive.
The 2.5-inch drives in the G3-series work with a 3-GBit/s-SATA-Interface, the theoretical transfer rates of up to 300 MB / s possible. The maximum reading rate indicates SanDisk 220 MB / s, write rate will be up to 120 MByte / sec. The mean time between failures (Mean Time Between Failures, MTBF) is according to the manufacturer for two million hours.
The power consumption is of Solid State Drives access while at 0.4 watts. At idle, the consumption drops to 0.3 watts. The company believes in keeping the memory operating shock of up to 1500G. They support Windows XP, Vista and 7 as well as Linux and Mac OS X.

Without TRIM support for SSDs can use the service after a prolonged partial decrease considerably. The reason for this lies in the physical characteristics of flash cells, which are used for the SSD models. Flash memory can be described only with no wait states, if the cells are empty.
Since the operating system files but only delete the contents of the file system and the controller of the SSD of this deletion will notice anything, it must delete the access back into the cell, these first before he can describe it. With the TRIM feature shares the operating system with the SSD controller, the data blocks are no longer used, so that it can delete the unused cells of rest, in order to later describe without loss of performance again.
