Samsung has started mass-production of 2.5" 25GB and 50GB SSDs for the enterprise segment. The drives are built using single-level-cell NAND flash technology (consumer-based SSDs are generally constructed using multi-level-cell NAND because it is cheaper, but also less durable). The new drives offer 100MB/s sequential read and 80MB/s sequential write speeds, consuming only 1.5W while operating and 0.3W idle. While the Samsung solid state drives offer improved capacity for SLC and maintain a 100 times greater input/output operations per second (IOPS) lead over typical 2.5" 15,000-RPM hard drives, the performance does not come close to that provided by the Intel X25-E Extreme SSDs.
