Industrial mSATA SSDs

Our mSATA SSDs support advanced wear levelling, through which all NAND flash components in a drive are treated and operated as a unified management unit for data storage. The higher the total capacity (more spare memory for spare blocks), the higher the durability of the SSD. Advanced wear levelling maps logical addresses of the host device evenly and randomly into physical addresses of NAND Flash.

The wear of mSATA SSD can be monitored by reading out the S.M.A.R.T. data. S.M.A.R.T. stands for ‘Self-Monitoring, Analysis and Reporting Technology’. The tool can be used to display and monitor the current status of an SSD, such as the remaining write/erase cycles or the raw read error rate and wear. This information helps to assess the probability of a drive failure and, if necessary, to save the data in time and to replace the SSD.

The PLP (Power Loss Protector) on the mSATA modules prevents data loss and write errors that could occur during a sudden power failure. This solution provides sufficient power to bridge voltage fluctuations. Unlike the usual SuperCap solution, which loses its performance at extreme temperatures, the Power Loss Protector is independent of the controller or firmware thanks to its standalone hardware, and is insensitive to temperature fluctuations.

The TRIM command enables mSATA modules to perform two functions: 1. searching for a free, writable block when the system detects invalid data in a block; and 2. searching for the best time to perform garbage collection and recycle additional free blocks. Random writes can thus be optimised and sequential writes can be re-sequenced in longer fragments. The modules will therefore perform constantly at optimum level.
