@Zeusk is right, I wish costs of SSD-RAMs like Diablo Memory1 [1] were more affordable or transparent.

Summary performance comparison by Storage Class: http://xitore.com/what-is-nvm-x

    NVM-X RAM ≈ DDR4-3200 ↧Availability|↥Cost| ↥4TB@25,6 GB/s
    Diablo Memory1        ↥Availability|↥Cost|↱256GB@10GB/s
