StarWind RAM Disk White Paper

Semiconductor technology is constantly evolving, basically following Moore’s law, so microcircuitry goes
denser and more efficient all the time. As a result, the average installed RAM size has increased
thousandfold over less than ten years and it’s not planning to stop. At the moment, it’s quite affordable to
have RAM of the same capacity as some five-year-old HDD, so that opens room for some new scenarios.


It’s a common thing to require storage of extremely high performance, during mostly test and
development, troubleshooting process or some niched deployments like online payment services or onthe-fly
encryption. In these cases, size and data volatility are factors of lower importance, because the
used data is usually temporary. Traditional solutions, like the superfast PCIe memory and newly-developed
NVMe flash, are expensive and not always available when needed “right now”. Besides, for test and
development, it’s most definitely overkill to utilize such advanced and costly measures.


StarWind RAM Disk takes a part of the RAM and creates a virtual storage device usable as a disk of
tremendous performance. The fact that data is deleted after reboot is not really important in the
discussed cases. This approach is very convenient because any installation has RAM available, thus no
additional hardware is purchased. Thus, StarWind RAM Disk becomes an optimal solution for test and
development, troubleshooting process or some niched deployments.


StarWind RAM Disk creates a high-performance virtual disk from RAM, offering a near-perfect solution for
test and development scenarios, troubleshooting cases or other niched deployments, where size and data
volatility don’t really matter.
