Product Features
1.2.
Cactus Technologies Industrial SSD contains a high level, intelligent controller. This intelligent
controller provides many capabilities including the following:
• Standard ATA register and command set (same as found on most magnetic disk drives).
• Manages details of erasing and programming ash memory independent of the host system
• Sophisticated defect managing capabilities (similar to magnetic disk drives).
• Sophisticated system for error recovery using powerful error correction code (ECC).
• Intelligent power management for low power operation.
1.2.1. Host and Technology Independence
Cactus Technologies Industrial SSD appears as a standard ATA disk drive to the host system. The
drive utilizes a 512-byte sector which is the same as that in an IDE magnetic disk drive. To write or
read a sector (or multiple sectors), the host computer software simply issues an ATA Read or Write
command to the drive as per the ATA protocol. The host software then waits for the command to
complete. The host system does not get involved in the details of how the ash memory is erased,
programmed or read as this is all managed by the built-in controller in the drive. Also, with the
intelligent on-board controller, the host system software will not require changing as new ash
memory evolves. Thus, systems that support the Cactus Technologies Industrial SSD products
today will continue to work with future Cactus Technologies Industrial SSDs built with new ash
technology without having to update or change host software.
1.2.2. Defect and Error Management
Cactus Technologies Industrial SSD contains a sophisticated defect and error management system
similar to those found in magnetic disk drives. The defect management is completely transparent
to the host and does not consume any user data space.
The soft error rate for Cactus Technologies Industrial SSDs is much lower than that of magnetic
disk drives. In the extremely rare case where a read error does occur, the drive has sophisticated
ECC to recover the data.
These defect and error management systems, coupled with the solid-state construction, give
Cactus Technologies Industrial SSDs unparalleled reliability.
