    Just in case you have not seen this tutorial or need a reference:

    Good luck.

    Windows 8 Pro


    Oh, thanks! I used it + format with UEFI BIOS tutorial when I bought the SSD.

    By the way, I downloaded the Windows 8.1 with the method on the following URL:
    http://mcakins.com/2013/10/19/downlo...ndows-8-0-key/

    Does this ISO contains only W8.1 (update) or it contains everything (I can format using this only ISO)?

    And my "test" is: Will W8.1 use this amount of Disk writing/reading with nothing but system installed? 😊

    Do you guys, think is valid or wasting of time (and also wasting of "writes" on SSD).

    Thanks a lot! I really appreciate your help. 😃

    If you downloaded the full Windows 8.1 ISO, it will contains the full 8.1 OS. Personally, I don't think you test will prove much of anything and I do think it is a waste of time because what happens if you find a tiny difference? What would be your next step? And there you go again about "wasting writes to an SSD."

    Also, make sure that you don't get "stuck" when trying to do a clean install if/when you decide to do so. That attempt will require "two" keys:

    A generic key that has to be used to complete the Win 8.1 ISO installation.
    Your authentic Windows 8.0 Pro key to "activate" the installation after the initial install.

    Hopefully, the tutorial you followed also made reference to the generic 8.1 key that is required. However, if not, this post shows you the correct key to use for Windows 8.1 Pro.

    Good luck with all your testing.

    Out of curiosity I tested my SSD (Kingston v300) few times and apart of some speed improvements after QC did it's job did not find any difference while only Windows was installed "clean" and subsequent tests as long there was about 10- 15% free. Due to some snafus I had to return image few times but even that did not change anything as far as SSDs speed is concerned. Had some improvement when I installed newest drivers for AHCI on my MB thou.
    As far as constant testing of drives is concerned, I have a friend that ruined couple of HDDs by constant testing and defragmenting until he got the idea that it shortens life of them, that's time when they are working much harder than in normal use. Unless you have a reason to suspect that something is wrong I'd refrain from testing them too often.

    Thanks again for the support.

    I will drop the test for now... Like I said, my worry was about how critical is this usage. Thanks your opinions, I can see if it's not "normal", at least is not dangerous.

    And I'm good with that.

    Again, thanks.
