SSD-HDD Price Gap Won't Go Away Anytime Soon 256

As SSD density increases, reliability and performance decrease, creating a dilemma for manufacturers who must balance density, cost, reliability and performance. '[F]lash technology and SSDs cannot yet replace HDDs as primary storage for enterprise and HPC applications due to continued high prices for capacity, bandwidth and power, as well as issues with reliability that can only be addressed by increasing overall costs. At least for the foreseeable future, the cost of flash compared to hard drive storage is not going to change.'"

    Well, 256GB SSD ought to be enough for anybody, and is relatively affordable.

    enough is never enough.

    This actually has nothing to do with drum memory. It's a part of the
    UUCP system.

    Long, long ago, even before version 6, somebody wanted to implement a
    program to copy files between two machines running Unix. At the time
    there were no modems becuase there weren't even any telephones. A
    Bell Labs researcher who had just visited Africa seized upon the idea
    of communicating by beating on drums, as the native Africans did. He
    added a drum interface to his PDP-11 and the device driver was called,
    of course, /dev/drum. Uucp would call a lower level program called
    `bang' to activate this device driver. Messages could also be sent
    manually by typing `bang drum' at your shell prompt. People soon
    devised shell scripts that would take a mail message, convert it
    appropriately, and call bang to send it. Soon they were sending
    multi-hop messages though several sites this way, which is how the
    `bang path' got its name.

    With the advancements in communications technology (semaphores in
    particular), /dev/drum was removed from UNIX around version 6 or 7, I
    believe. The NeXT developers reinstated it on the NeXT because they
    felt that a true multimedia machine should have as many options as
    possible.

    I hope this explanation helped.

    Hilariously, that is the first actually valid reason to switch from 7 that I've ever heard.
