Cactus Technologies, Limited
1.1. Supported Standards
Cactus Technologies
®
-910S/910S-P1 series SSD is fully compatible with the following
specification:
·
ATA 8 Specification published by ANSI
·
Serial ATA 3.0 Specification published by the Serial ATA International Organization
1.2. Product Features
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 flash 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 SATA 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 SATA protocol. The host
software then waits for the command to complete. The host system does not get involved in
the details of how the flash 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 flash memory evolves. Thus, systems that
support the Cactus Technologies
®
Industrial SSD products today will continue to work with
future Cactus Technologies
®
Independence SSDs built with new flash 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 SSD 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.
