Today’s SSD’s the way they are connected to the motherboard are usually through SATA/SAS or PCIe. However those interfaces are still limited in bandwidth and access times resulting some latency, even compared to spinning disks  SSDs  via SATA/SAS or PCIe offers superiour performance and low latency. Diablo Technologies offers superior performance and lower latency by placing SSD chips via  modules  which are plugged where usually RAM Memory chipsgoes. This Memory Channel Storage Solution offers parallel access to the SSD’s present in those RAM slots the access times are the fastest ones and the latency lowest.

Memory channel storage is incredibly fast. As fast as the difference between SSDs and spinning disks. Plus, I’m a fan of bringing back “Memory Channel” as a computer acronym.
