    Optimize SSD


    Since I've installed a SSD, When I run Optimize it says never run-needs optimization. It will never run on it. Any suggestions?

    Recovery is a special system volume that is built during install, and used only to launch recovery if and when the primary boot sequence fails to complete (or if you invoke recovery through a variety of OS options in Windows, like "Reset this PC"). Notice it has no drive letter. It doesn't need to be optimized because (a) it's on an SSD and Windows doesn't optimize SSDs and (b) there's not much or any write activity to this partition so the structure doesn't degrade (much) over time. Feel free to ignore this bogus warning. FWIW, I see the same thing on my PC and I never heed that admonition.

    Take a look here, it does optimize SSDs, it runs TRIM: Optimize Drives - Defrag HDD and TRIM SSD in Windows 8

    I think the reason why it won't perform optimisation on the recovery partition is because there (appears) to be nothing in that particular partition to optimise.

    Thanks, Swarfega: that's what I tried to say, too. As for TRIM, it's just glorified garbage collection. Not quite the same as optimization, but then, SSDs don't need to move data around to get it under a read/write head ASAP, either. Random access rules!

    It's called Optimize Drives, because it both defrags HDD's and TRIM's(which is not garbage collection see below), and they needed and one name fits all.

    It has nothing to do where files are placed on the drive like "so called advanced defragmenters" do(which for a normal user is a waste of time and also causes wear & tear on mechanical drives for very little to no increase in access time)

    GC(Garbage Collection) is the name for the process of relocating existing data to new locations and allowing the surrounding invalid data to be erased. Flash memory is divided into blocks, which is further divided in pages. Data can be written directly into an empty page, but only whole blocks can be erased. Therefore, to reclaim the space taken up by invalid data, all the valid data from one block must be first copied and written into the empty pages of a new block. Only then can the invalid data in the original block be erased, making it ready for new valid data to be written.


    the TRIM command enables the OS to notify the SSD that old data is no longer valid about the time it deletes the logical block addresses from its logical table. The advantage of the TRIM command is that it enables the SSD’s GC to skip the invalid data rather than moving it, thus saving time not rewriting the invalid data.

    Leave the Recovery partition alone. As stated, there is probably nothing to optimize there.

    Hi there

    In the nearly 30 odd years I've been using various releases of Windows and Linux I've NEVER had to defrag a drive -- AFAIK it rarely seems to make ANY difference.

    As for SSD's -- since essentially accessing data is really like reading a 2 dimensional array where any address is just as likely as any other and the access time the same (no heads to move or seek cylinder / sector stuff to perform) then there's nothing to do.

    The best you can do with an SSD is JUST LEAVE IT. Any fiddling with it is more likely to break it than just by using it normally.

    (Even if by some convoluted maths and twisting the Laws of Physics you could theoretically get a microscopic improvement - the amount of improvement would be so tiny that you would be unable to detect it anyway).

    A lot of advice on HDD's etc is really OUT OF DATE now - especially with large spinners which have decent cache sizes, "pre-fetch" for commonly used data etc.

    If you have an OS on a spinner - the best you can do is to back it up with something like macrium, re-format the HDD and then restore the IMAGE. IMAGE the HDD - don't use CLONE. Imaging will essentially "optimise the OS arrangement" on the HDD -- Cloning will copy sector by sector -- empty ones too etc.

    It always is best to keep your OS and programs if possible on its own HDD / SSD. Certainly keep in a separate partition. One obvious benefit is that if you have to restore or upgrade the OS you don't lose your DATA !!!.

    Cheers

    Its very difficult to get definitive easy to understand info on SSD trim and optimise.

    Have you noticed that when you restore an image with Macrium that it says at the very beginning 'attemptimg trim... trim successful'. Also Windows default is to 'optimise weekly' and yet that doesn't seem to happen from what I can judge. My recovery drive contents never really change and yet that now says needs optimising. Only just spotted that.

    Sorry, but that's just not correct. On HDDs it DOES make a difference. In fact it may well turn a sluggish system into a much better one. HDDs are mechanical so seek times are for real.

    As for this recovery partition, nothing's written to it so leave it be. It's one of these things MS still needs to address, it should not show up there as needing Optimization that's all.

    Cheers,
