At the very top there is dynamic DRAM memory which in short can be said to be the fastest but the data is volatile and without voltage it is lost forever. Intel Optane with innovative D XPoint technology The name of the D XPoint technology results from the structure of the memory cell which resembles a three dimensional chessboard Figure . Compared to DRAM this approach allows for a x increase in data density which in turn means the ability to store more data and lower production costs.
Figure Construction of D XPoint | nam Figure . Construction of D Xramid Figure . In real use Intel Optane memory can boast a read speed of . GB s and a write speed of . GB s while the NAND SSD has a Phone Number List read speed of . GB s but only a write speed of . GB s. Adding to this the number of input output operations per second IOPS of when reading and when writing a K block Intel Optane drives turn out to be created specifically for the needs of databases.
Table clearly shows that the D XPoint technology used in Intel as SSD but with a latency in accessing them only x greater than DRAM. In turn SSD can have a latency that is up to x greater than volatile DRAM. Intel Optane drives can boast such values thanks to the above mentioned structure Figure and an advanced controller for their operation. Table . Memory size and latency relative to DRAM | nam Table .
