14 DAY TRIAL // Until recently, DRAM and NAND did not mix. Even NAND and HDDs had an easier time, since they were both meant to store things in the long term. Now, though, we finally have an SSD-DRAM hybrid.
SanDisk has launched the ULLtraDIMM Solid State Drive, which happens to be the first “enterprise-class, ultra-low latency, memory channel storage solution.”
It is basically an SSD that goes into a DIMM slot, the common type of slot for random access memory in a PC, normally filled by DDR3.
It should enable a much shorter app response and can scale performance and capacity of system memory without affecting latency.
SanDisk made the ULLtraDIMM SSD for enterprise data centers and existing flash-based servers. IBM will use them, among others. From what I could gather, the ULLtraDIMM can have 200 GB capacity.
