The Zeus controllers gain performance in this generation by a shift from an FPGA (field-programmable gate array) to an ASIC (application-specific integrated circuit) architecture in the silicon that runs them. ASICs can be more highly integrated and are less expensive than FPGAs, Stetzer said.
Also in the fourth generation, STEC is adding the option of 256-bit AES encryption to create a self-encrypting drive, so data can't be retrieved from the SSD if it is removed from the array where it belongs.
Zeus is STEC's line of SSDs with Fibre Channel and SAS (serial-attached storage) interfaces, while its Mach series uses SATA (serial ATA).
