Windows 10: Solid-state drives lose data if left without power for just a few days

    No matter how fast the data was found by the SSD, it can't get into the CPU or RAM any faster than the SATA controller can process it. SATA I, SATA II or SATA III data transfer speeds are fixed by hardware and cannot be increased.

    My little SSD really didn't seem to be any faster than my old SATA III hard drive, because both were running on a SATA II motherboard. For an SSD to really shine, it would have to be connected to a drive controller that is much faster than even a SATA III.

    I dunno. It seems to me that the spinning disk is the bottleneck more often than not these days. Whether you are talking 3gig or 6 gig Sata, the spinning disk can't keep up with either and you don't get even close to making use of even half of that throughput, or achieving those results until you step into the SSD world. The difference is absolutely apparent. Perhaps the SSD you purchased was a slow one.

    I have never lost data from SSDs some of which I use since 2008. And some are not being used for at least 6 months when I am on the other side of the Atlantic.

    When SSD's first came out, I took all the hype with a grain of salt.
    I've been working with the mechanical HD's since they were still in their infancy. (back into the '60's).
    I doubt that very many on this or any forum today, would even know what an MFM or RLL drive was.
    Oh, please. There are more old farts here than anywhere else I've been. I'm in my mid-40's and I still remember my 5MB (yes, Megabyte) MFM ST-506.

    In those days, if you let a drive sit too long, the lubricant would seize the head to platter or the bearings would seize, this was called "stiction" and you often had to hit the drive with a hammer to free it up.

    Data loss in dormant SSD also depends on how hard they have been used. The more erase cycles, the less the data retention period. Usually quoted data retention lifetime is specified at the rated Program Erase cycles of the SSD (i.e. when the SSD can no longer be written to reliably), which is the worst case retention lifetime. This is how he JDEC SSD specification says it should specified.

    No idea. But you surprise me. From your Avatar you don't look a day over 60. lol.


    Hi Lee,
    No boast, as I am sorry to be on the way out, but I am old enough to remember when computers were things you only saw in kids comic books.
    All in my profile, no secrets needed with me.

    All the more reason to have multiple backups.

I am planning on reserving Windows 10 on my Windows 8.1 computer and I wanted to know if I will lose everything.
Just sharing this. I made another boo-boo today and deleted 500GB worth of media files (just movies and music). Don't ask me how because that's something nobody wants to do. :) I don't keep a backup of these files. For me these are disposable...
