1.1. Supported Standards
Cactus Technologies
-900 Series SATA SSD is fully electrically compatible with the following
specification:
•
ATA 8 Specification published by ANSI: X3.221 AT Attachment Interface for Disk Drives
•
Serial ATA 2.6 Specification published by the Serial ATA International Organization
1.2. Product Features
Cactus Technologies
-900 Series Industrial SATA 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
-900 Series Industrial SATA 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
-900 Series Industrial SATA SSD products today will continue to work with future
Cactus Technologies
-900 Series Industrial SATA SSDs built with new flash technology without
having to update or change host software.

Defect and Error Management
Cactus Technologies
-900 Series Industrial SATA 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
-900 Series Industrial SATA 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
-900 Series Industrial SATA SSDs unparalleled reliability.
