Solid state drives based on flash memory cards have many advantages, but not without flaws. In particular, the performance of flash-type NAND can become a bottleneck even the most high-performance system. To circumvent this shortcoming, engineers DDRdrive combined in one product dynamic random-access memory (DRAM) and flash-type NAND. Form a solid-state drive DDRdrive X1, made in the form of expansion cards with the interface PCI Express x1.
Reservoir is equipped with 4 GB of memory-type DRAM (four standard module volume by 1 GB each) and 4 GB of memory type NAND. The company estimates that the device is up to 300,000 input / output operations per second (IOPS) on the reading mode and 200,000 IOPS in the recording mode. These figures are for 2000% superior performance of conventional high-speed SSD, such as the Intel X25-E, and better than even the «very quickly» solid drive Fusion-io ioDrive Duo, released last month. Claimed to read and write speed of greater than 215, and 155 MB / s, respectively (For the sake of justice - there DDRdrive X1 yields not only ioDrive Duo, and Intel X25-E). Several drives can be included in the configuration of RAID 1, 0 or 5.
What's more novelty «superior» Intel X25-E, is the price, especially given the recent decline in the price of SSD Intel. If the Intel X25-E level of 32 GB is $ 390, the manufacturer DDRdrive X1 appreciated to $ 1495.
