SSD Latency, Error Rates May Spell Bleak Future

Lucas123 writes "A new study by the University of California and Microsoft shows that NAND flash memory experiences significant performance degradation as die sizes shrink in size. Over the next dozen years latency will double as the circuitry size shrinks from 25 nanometers today, to 6.5nm, the research showed. Speaking at the Usenix Conference on File and Storage Technologies in San Jose this week, Laura Grupp, a graduate student at the University of California, said tests of 45 different types of NAND flash chips from six vendors using 72nm to 25nm lithography techniques showed performance degraded across the board and error rates increased as die sizes shrunk. Triple-Level NAND performed the worst, followed by Multi-Level Cell NAND and Single-Level Cell. The researchers said MLC NAND-based SSDs won't be able to go beyond 4TB and TLC-based SSDs won't be able to scale past 16TB because of the performance degradation, so it appears the end of the road for SSDs will be 2024."

    Yes, but what I heard about PRAM is that you have to push it. A lot.

    A warp core really isn't a power source. It is more like an alternator. The power source is the matter-antimatter reactions. Similarly people confuse dilithium crystals with being a power source when they are really just a matter-antimatter regulator.

    And now, back to reality...

    Still waiting for the Holographic Memory that should have been hear a decade ago.

    - there is the problem.

    With holographic memory you shouldn't be trying to 'hear' anything, it's something likely in visible electromagnetic spectrum instead!

    On behalf of my fellow Brits I would like to apologise, and assure you that henceforth we shan't abbreviate the full term, perambulator. Let's face it: pushing an overloaded baby carriage (including baby, nappy bags, bottles, snacks, toys, etc.) is a long way from being the "leisurely walk" for which the word "stroller" would be appropriate.
