Cactus Technologies' design of the 900S series industrial grade SATA II SSD takes into account the challenges faced by Industrial Embedded Applications - unexpected power loss, high shock & vibration, operating temperature extremes and long life cycles. In order to test the abilities of write abort protection, the Cactus 900S SATA SSD was subjected to continuous random power interruption cycles while data was written. Cactus claims that during extensive testing, its Cactus 900S Series performed better than any other SSD.
"This is due to the high reliability SLC NAND, lack of susceptible DRAM cache and a controller designed for reliability algorithms at the core," the company said.

Write abort protection is an issue for Embedded OEM system designers. If power is unexpectedly removed from the SSD during a write cycle, SSD updating their internal meta data during a power interrupt may become corrupted or even unusable.

Extreme Shock & Vibration environments quickly find and exploit the weakest elements of an SSD design. For this reason, the 900S SSD was created with an 8-layer PCBA and Die Cast Steel Chassis as opposed to 4-layer PCBA with plastic or stamped steel.

Wide Temperature Extremes wreak havoc on lower end SSD mainly due to their use of lower reliability NAND flash not intended for this purpose. The 900S SATA SSD only uses extended temperature SLC NAND flash from the foundry, which has been qualified to operate for life within a -45C to 90C environment.

Locked-BOM Control ensures the 900S Industrial Grade SATA SSD purchased years from now will remain the same as the part shipping today. Without a notification to the purchasing OEM, there are no changes to the physical makeup of the SSD, Controller Silicon / Firmware and SLC NAND Memory used.
