Introduction to Cactus Technologies®

Commercial Grade -270PM6 Series M.2 SSD ProductsCactus Technologies® Commercial M.2 PCIe SSD is a high capacity solid-state flash memory product that complies with the PCI Express base standard v3.1 and NVM Express v1.3 standard. It is a PCIe device that operates in native NVMe mode. Cactus Technologies® Commercial M.2 SSD provides up to 512GB of formatted storage capacity.
Cactus Technologies® Commands M.2 SSD product uses high quality 3D TLC NAND flash memory from Kioxia Corporation (formerly Toshiba). In addition, it includes an on-drive intelligent controller that manages interface protocols, data storage and retrieval as well as ECC, defect handling and diagnostics, power management, and clock control. The controller’s firmware is upgradeable, thus allowing feature enhancements and firmware updates while keeping the BOM stable.

Supported Standards

Cactus Technologies® M.2 SSD is fully compatible with the following specification:

• PCI Express base specification, ver. 3.1, published by PCI-SIG
• NVM Express Specification 1.3 published by NVM Express Organization

Product Features

Cactus Technologies® Commercial M.2 SSD contains a high level, intelligent controller. This intelligent controller provides many capabilities including the following:

• Standard NVMe register and command set
• 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.

Host and Technology Independence

Cactus Technologies® Commercial M.2 SSD operates in native NVMe mode. To write or read to the device, the host computer software simply issues a PCI memory Read or Write command to the drive as per the PCI Express 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® Commands M.2 SSD products today will continue to work with future Cactus Technologies® Commercial M.2 SSDs built with new flash technology without having to update or change host software.

Defect and Error Management

Cactus Technologies® Commands M.2 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® Commands M.2 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.
These defect and error management systems, coupled with the solid-state construction, give Cactus Technologies® Commands M.2 SSDs unparalleled reliability.

Power Supply Requirements

Cactus Technologies® Commercial M.2 SSD operates at a voltage range of 3.3 volts ± 5%.

NOTES: All values quoted are typical at ambient temperature and nominal supply voltage unless otherwise stated.
Idle mode is specified under the condition that all drive inputs are static CMOS levels and in a “Not Busy“ operating state.

System Performance

All performance timings assume the drive controller is in the default (i.e., fastest) mode.
The IOPS numbers are steady state values when the SLC cache partition is already full.

Note: Due to the high throughput of PCIe interface, the drive controller implements thermal throttling to prevent excessive die temperature which will damage the device. Thermal throttling will kick in when internal die temperature reaches 90°C. The drive’s rd/wr performance will drop significantly when thermal throttling kicks in. It is advised that the user provides adequate air flow in their system to reduce the likelihood of thermal throttling from happening.
