Cool Videos to Learn About SSD's and Flash Memory

  • SpinRite v6.1 Release #3
    The 3rd release of SpinRite v6.1 is published and may be obtained by all SpinRite v6.0 owners at the SpinRite v6.1 Pre-Release page. (SpinRite will shortly be officially updated to v6.1 so this page will be renamed.) The primary new feature, and the reason for this release, was the discovery of memory problems in some systems that were affecting SpinRite's operation. So SpinRite now incorporates a built-in test of the system's memory. For the full story, please see this page in the "Pre-Release Announcements & Feedback" forum.

  • BootAble – FreeDOS boot testing freeware

    To obtain direct, low-level access to a system's mass storage drives, SpinRite runs under a GRC-customized version of FreeDOS which has been modified to add compatibility with all file systems. In order to run SpinRite it must first be possible to boot FreeDOS.

    GRC's “BootAble” freeware allows anyone to easily create BIOS-bootable media in order to workout and confirm the details of getting a machine to boot FreeDOS through a BIOS. Once the means of doing that has been determined, the media created by SpinRite can be booted and run in the same way.

    The participants here, who have taken the time to share their knowledge and experience, their successes and some frustrations with booting their computers into FreeDOS, have created a valuable knowledgebase which will benefit everyone who follows.

    You may click on the image to the right to obtain your own copy of BootAble. Then use the knowledge and experience documented here to boot your computer(s) into FreeDOS. And please do not hesitate to ask questions – nowhere else can better answers be found.

Hi all. While doing a bit of research to respond to a question about SSD operation over on the ReadSpeed forums , I discovered a batch of YouTube videos related to understanding SSD operation. I decided to take them and put them in their own thread here for everyone to see. I find it useful to play informational YouTube videos at 1.5X or 2X speed to get through content faster. You can do that by clicking the gear icon on the tool bar.

Anyone is welcome to add to this thread. But, please keep it limited to the topic of SSD's and flash memory in general, as opposed to a specific SSD. That could include flash memory cards, memory sticks, or PCI cards. Please screen your videos before posting, and keep the language at a G or Everyone level. Some technical videos do have foul language and I'd like to avoid that.

Hope the info helps. See below.

May your bits be stable and your interfaces be fast. :cool: Ron
