  • Flash disks write cycles

    Hi,

    I am a bit confused. I know that CF cards have limited cycles of writing.
    But what about the USB stick? Does it have limited cycles too?
    And what about SSD?

    Thanks in advance

    Both CF and USB thumb drives are solid state disks and have limited write cycles.

      But how about notebooks with SSD? Do they have to change disk every year or what?

        Notebooks with SSD? Notebooks have a 2.5" platter drive. Not solid state. Unless your talking about something else.

          we did some testing with compact flash at work (1gb CF with CF to IDE adaptor and boot from them) and they worked fine for well over 100,000 cycles. we could not make them fail so we quit after that.

            Solid State memory of any sort have limited write cycles. The flash management has wear leveling algorithms to evenly wear out the flash chips to reduce corruption. There's also some spare flash cells inside that is used for emergency (hard drives also have extra hidden disk space for this reason as well).
