programs stall/delay? SSD the issue?

Note that this number is in Bytes, so if you have an offset of 1024 kB, it's still aligned. 4096 Bytes = 4 kB and 1024 divided by 4 returns an integer (256). Diskpart can also be used to check for alignment.

Load a command prompt with admin rights, type:

Code:

diskpart

list disk

select disk #

list partition

# is the number associated to your SSD if you have more than one disk.

 

Are there any side affects of doing this to an existing image? Does it decompress files that are currently compressed? Btw, I haven't set or manually compressed anything beyond what Windows does automatically which I think are only for a couple folders.

 

It wouldn't uncompress them. The way I found out about this tweak, is once after having Windows installed for about a week, I check my C: folder and I notice some folders are marked in blue so I quickly formatted and now the first thing I do when I boot to my desktop after a fresh install is DisableNTFSCompression = 1

4) Disable NTFS Compression, NTFS Encryption, and NTFS Last Access Update:

Note: If you have a SandForce based SSD, then do not disable NTFS Compression as the SandForce controller heavily relies on compression to give you optimal performance but for any other controller this will help to prevent data from ever being compressed then decompressed when needed.

Press the Windows + R Key on your keyboard to bring up the Run Dialogue box then type regedit

Navigate to:

Code:

[B]HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem[/B]

Double click on NtfsDisableCompression and set the value to 1

Double click on NtfsDisableEncryption and set the value to 1

Double click on NtfsDisableLastAccessUpdate and set the value to 1




Exit the registry editor then reboot

 

Thanks Ferris!

NTFS Compression - Disable or Enable

I can stop myself easily enough from wanting to compress something, however it is nice to have it grayed out so as not to accidentally do so. I do use file and folder encryption coupled with BitLocker so I'm not going to disable that one.

What is NtfsDisableLastAccessUpdate for, does it time stamp the last time the folder was accessed in explorer? if so, how much does it help speed up reads or reduce writes to an SSD?

 

In my case, I never did compress any folder, I don't know why when I went to C:\Windows I found some folders in blue meaning they're compressed so now just for safety I always disable compression.

NTFS Last Access Update is usually disabled by default with a value of 1 if Windows detects you have an SSD but the reason I included that in the Tweaks is just to ensure that you have that value of 1

What it does is it leaves a stamp on each file when it was last accessed. Unless you are in a corporate environment, I don't see a reason to have that as it would only add small extra writes to the files.

 

Yup - it's a (1), by default. Error was my bad - totally didn't register earlier when I looked straight at it.

Thanks.

 

FYI i think when i click trim it actually trims unallocated because when i have 100% of space allocated when i click run TRIM it comes instantly but when i have 110GB unallocated it takes like 20 seconds to finish TRIM, which means it must actually be TRIMing the unallocated space.

 

Possibly. I might have to test this in the future.

Thanks for the update.

 

all these 26 other steps and ideas will have to wait a while before i get a chance. I got to read up on them to understand the process. Or tiller you just want to come over and do it for me..for free

Tiller and ferris, you guys should make a guide to proper SSD set up and tweaking.

 

Your wish is my command
