OCZ makes 1.8-inch SSDs with up to 240 GByte storage


Until now, the Onyx series of drives and vertex 2 is only 2.5-inch format were available. The vertex models achieve read rates of up to 285 MByte / s. All SSDs support the TRIM command of Windows 7


OCZ Techology has announced 1.8-inch version of its SSD series Onyx and vertex second The flash drives were previously only in the 2.5-inch format.


The Vertex-2 series includes models with 60, 120 and 240 GB of storage capacity. They provide, in combination with one according to the manufacturer 3-GBit/s-SATA-Interface maximum transfer rate of 285 MByte / s read and 275 MB / s when writing. Access time is less than 0.1 milliseconds. The write performance at 4 KByte small data blocks is 50,000 input commands per second (IOPS).


The mean time between failures (Mean Time Between Failures, MTBF) is OCZ to two million hours. The Stoßresistenz is specified with a maximum of 1500 G. In operation, the drives consume about 2 watts in sleep mode about 0.5 watts.


RAID support is also on board as TRIM support dell latitude d830 battery. The Windows 7 supported TRIM command creates a continuous high performance of SSDs. It shares 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.


Without TRIM support for SSDs can use the service after a prolonged partial decrease considerably. The reason for this lies in the physical features 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.


The 1.8-inch models of the Onyx level series are available in capacities of 32 and 64 GByte. They also support the TRIM command.


The transfer rates vary depending on memory size: The 32-gigabyte version according to the manufacturer creates up to 135 MByte / s read and up to 70 MByte / s in writing mode. With the 64-gigabyte version, it is 145, respectively 120 MByte / s. The 4-Kbyte-write performance of 15,000 IOPS.


Prices OCZ has not yet announced. Some online retailers such as lenovo ideapad s9 battery Alternate listen to the 1.8-inch drives in the Vertex-2 series, however, already. There they will cost, depending on memory size between 230-870 €.
