The Challenge

Sudden power loss events are detrimental to solid state drives (SSDs). They can corrupt data or render the storage device unusable. While power loss protection (PLP) mechanisms are available on most industrial SSDs, the need for more intelligent power management and power loss protection cannot be underscored enough. ATP customers want constant assurance that power loss events will not cause massive downtime or lost data that could affect business operations and lead to higher operating costs.

The Solution

ATP completely redesigned the PLP array on its next-generation SATA SSDs and NVMe SSDs. Integrated into ATP PowerProtector 4, the completely new design of the PLP array utilizes a new power management IC (PMIC) and new firmware-programmable MCU that allow the PLP array to perform intelligently in various temperatures, power glitches, and power states.

The Result

The MCU intelligently monitors sudden power failure conditions from a glitch to a surge or a complete outage and performs the necessary action to protect both data and device. Over-input voltage protection, power-up inrush current suppression, input power noise de-glitch, and fast power on-off control are among the benefits that the new MCU-based design offers to make sure that mission-critical tasks will not be compromised and the customers' total cost of ownership (TCO) yields the best value.

BGA SSD: Powerful NVMe Performance in a Tiny Package

ATP‘s N700 Series SSDs are built with 3D triple-level cell (TLC) configured as pseudo-single-level cell (pSLC) NAND flash. By storing only one bit per cell, they increase the reliability and endurance of the NAND flash memory, while benefiting from the lower cost compared with native SLC, due to the higher cell density.
