SSD Tweeks

SSD users are told to disable:

defrag

indexing

all types of "fetching"

What I found:

Disabling defrag OK, but I recommend defrag in manual as well with auto defrag in scheduling disabled. Reason being is if you have an external device you want to defrag Windows wont allow it if it is disabled. In manual you can defrag any external device or internal HDD you may still have hooked up.

Disabling Indexing, not so good. Disabling indexing (windows search) disabled my documents link. Instead of disabling indexing (windows search) I placed it to manual and all works fine.

Disabling fetch, prefetch, super fetch, whichever one you have actually slows down the SSD boot up time. For me it was close to ten seconds. I enabled superfetch back to automatic and boot-up time increased seven to 10 seconds each time it was timed, I also read an article that recommmended prefetch reamin enabled stating RAM is still faster than the SSD, and he appears to have been correct.

If your Windows version still has "Hibernate" as an option on your desktop and you never use it, you can disable this function and gain an amazing nine GB or so of space on your SSD. (probably your HDD as well).

To disable the "Hibernate" mode:

Accessories / right click-command prompt / select-Run as Administrator

at prompt ">" type in this command............powercfg -h off...................include the space betweed "g -h' and between "h off"

To turn hibernate back on replace the "off" with "on"

    Good info and I did turn off my auto defrag in Norton and do manual defrag in Windows for my non-SSD drives. Also turned hibernate off. As to indexing, I couldn't find any way of placing it in manual but I used the Advanced tap to move the Search folder from the SSD drive to a partition of my NON-SSD drives. Does that not solve the indexing issue as to SSD drives?  Or am I misunderstanding the issue?  If not, any thoughs as to the location of the Page file?

    Right click the drive in my computer, click properties and uncheck the box for indexing at the very bottom. 

    I keep off hibernate,prefetch,superfetch,indexing,defrag and windows search. I leave the pagefile alone. I know some that make a folder on a HDD for the pagefile and some that just turns it off. I leave it on so some of my programs will play nice:)

    Here is an article about SSD tweeks. It is a bit dated as most SDD's have Trim software enabled and I would stay away from the section that has you fool around with the registry. Otherwise it is informative.

    You can change how indexing works by:

    Administrator Tools / Services / Windows Search...........

    right click on Windows Search and selesct Properties. In the General Tab, in the middle of the page is Startup Type with a pull down menu. From the pull down menu you can select Manual.

    As far as Pagefiling goes, it is located in:

    Control Panel / System / Advanced System Settings.........

    From there, select the Advanced tab. On that tab select Settings under the Performance section. A new window opens titled Performance Options. Select the Advanced tab. Here you will see Virtual Memory, select Change. A new window will open titled Virtual Memory. Enable the dot that says No Page File. A prompt will pop up asking if you really want to do this. Select yes........ONLY IF

    ......... you have six or more GB's of Memory. The Virtual Memory is space on a HDD that is used when not enough ram is available when your system needs it. Ram is much faster than the Virtual Memory and rarely does Windows require more than six GBs of memory to handle whatever you are doing. Buying a whole lot of memory doesn't do much for performance if it is never used. A smaller amount of memory at higher speeds is best (learned that after buying too much memory myself).

    Your HDD or SSD space is reduced by the amount of Ram you have in your system. You can also manually set the System virtual memory to whatever you want. By disabling Pagefile, you gain back an equal amount of drive space as you have ram if Windows was automatically running the Virtual memory.

    Turning of Pagefile forces your system to use the much faster Ram. If you have six or more GB of Ram you will not have any issues running anything on your system. If by chance you do, you can manually set the amount of Virtual memory to compensate while reducing the loss of drive space.

    I have 12GB of memory. I turned off pagefile and gained back 12GB of space on my SSD and have never had any issues running anything.

    AAA737flyer.

    Now I am confused or it is just my old brain being on it's last legs and not just my memory.

    I thought the SSD problem is to reduce unnecessary "writing" (no problem with "reading" which is not restricted by fragmentation).  So in in turning off the boot SSD drive/partition from having it's content indexedwould turn off indexing altogether if this is the only drive/partition. But if, as usual on today's set-ups, there are more drives/partitions, those other drives/partitions are still indexed creating changes to the database in the Search Folder.. 

    Since it is my understanding the Search Folder is created by default on the Boot drive, there is still a lot a data being written/updated on the Boot drive, now just without any data FROM the boot drive.  Whereas moving the Search folder to a NON SSD drive, eliminates the writing/updating of this info on the SSD drive yet still indexing it's data, as well as that of other drives/partition. Yes a search would now look up the info on a "slower" drive but it would still be faster than turning indexing off completely. 

    Am I missing the point? i.e. does indexing not just mean creating a database in the Search folder or does it also entail a writing (if so a one-time change) for each file in the File Allocation Table, or whatever it is called now?   If the latter, I, for one,  would also have to then eliminate the indexing of my Data partiion, basically elimination the major benefit of indexing.  And would then turning it off again mean a write to that Table for each file which was already on the indexing system for that drive?  Like, I can see, the purposed of not indexing a drive/partition would be as a prime example that I do perhaps not wish to use indexing for my "Data Back-up" partition on a physically different drive, to avoid all those duplications showing up in a search.

    Still have to read up on prefetch/superfetch to find out what that means and how it impacts on the writing aspects on a SSD, i.e. is there also a Database created for applications and if so where is that database storred?

    There are a lot of discussions on the web. You can Google any topic and find most anything you need to know about SSD's.

    In short, an SSD doesn't need indexing because it is that fast. I found however, that by turning indexing off (disabling) that my "Documents" link in startup did not work. By placing indexing in manual mode the link worked and indexing remained off. You can also select which drives to turn indexing off or leave on.

    A quick Google search found this:

    Indexing creates and maintains a database of file attributes. This can lead to multiple small writes when creating/deleting/modifying files. Searching for files will still work.

    FWIW, I did some googling on the System Restore issue and found a mixed bag of recommendations. One of things I found was that the newer Intel Optimizer now correctly handles system restore points - there was no recommendation to turn it off. Also, most of the documents that recommend turning off system restore because of the interaction with TRIM reference the SAME article as provided in the link - I could not find any other independent reference. Maybe someone else can.

    So, I'm still not convinced that there is an issue with having system restore enabled.

    I left my system restore on as well. Intel has software with its drives that it uses to turn off all that it wants off. (intel toolbox)

    The only thing I have noticed about the system restore is that it will continue to use up space even if you don't use it. Delete all restore points and then create a new one. It will be around 235mb. After a short time without doing anything that would need a restore point, look at the space used and you will notice the restore space has increased. It can double after just a few hours.

    Depending on the amount of space you allocate to system restore, windows will continue to use it all over a period of time with or without the need of creating an actual restore point.

    Each vender is different so one tweak may work for one drive and not for a different manufacture. You can use this App to measure your drives speed after tweaking. The one article suggested turning off the write-cach funtion but not for intel drives. He was right. My write scores went from 65-80 back up to the 240-260 range after turning write-cach back on.
