Disk-on-a module (DOM) SSD Flash Drives are available in 1.8 inch and 2.5 inch form factors. These drives are much faster than a SATA III Hard Drive because they get connected to the motherboard and as no cable is involved, the data date is much higher than a SATA III connector.
A DOM flash drive can transfer data at a speed of 6-8 GBPS. The DOM SSD drives are available in 1.8 inch and 2.5 inch form factors. These drives are mostly used in harsh environments where extra peripherals cannot be connected to the main system.
