Solid State Storage

 

Solid-State Storage today is driven by the rapid innovations in Flash memory semiconductor technology. Being at the forefront of Moore's Law, Flash memory capacity will continue to increase while, at the same time, Flash memory cost will continue to drop. Unlike mechanical Harddisk Drives (HDD), Solid-State Disks (SSD)  do not contain any moving parts, making this the preferred storage technology to implement reliable Embedded Systems.

The underlying protocols to interface with SSDs are Serial ATA (SATA), Serial Attached SCSI (SAS), and NVM Express (NVMe). They stem from the PC and Datacenter world and, sometimes, put quite some processing burdon on a typical Embedded System CPU. To offload Embedded System CPUs and/or to accelerate storage bandwidth and latency, MLE has been working on Storage Protocol connectivity and acceleration Technology.
