Indexes -> NTFS

1 of my drives has, Max size: 1024, Allocation delta: 256
where all others are: 51200, 4096

why is that?

I too am curious how Everything arrives at the values it does for a volume's USN Journal. I'd also like to know the practical effect of larger and smaller values and how this changes performance and behavior.

I wonder if Everything should automatically handle these values itself through observation and management of resources, and allow the user to change them through /command or ini file instead.

The maximum size determines how many file system changes to store.
1MB will store about 1000 changes.

The allocation delta is how many entries to batch delete to keep the journal size under the maximum.



The system almost always creates the USN Journal and sets the maximum/delta sizes.
Typically, the system will create the USN Journal with the following values:
Maximum size: 32768 KB
Allocation delta: 4096 KB

If the USN Journal doesn't exist, Everything will create one with the following values:
Maximum size: 32768 KB
Allocation delta: 4096 KB

1 of my drives has, Max size: 1024, Allocation delta: 256

The system is most likely using a smaller value for this drive based on its total size.

What is the total size of the drive?
How old is the drive?

You can have a 64K journal or a 100 GB journal..
The Journal maximum size is not going to affect performance.

I do recommend keeping the allocation delta low (4096 KB - 8192 KB) as it does take some time for the NTFS driver to trim the USN Journal.

The journal does take up physical space on the drive.
The space used will be negligible. (eg: 32MB of a 1TB drive is < 0.01%)

How old is the drive?

(Assuming I'm thinking of the correct drive [unless I pop back in here & change it, lets go with that]), 8 TB, 2017.


(Yeah, pretty sure it was T:, & it's a Toshiba drive N300. Never would have figured it to be 5 years old at this point.
And... it's one of my newer drives .)

Code: Select all

HDWN180XZSTA was $230 at the time.  Happened to note the price of a 8TB Toshiba drive just yesterday. That is:
HDWG480XZSTA at $135.

(As far as that goes, my monitor, HP Omen 32" QHD (2560x1440), was $125, also 5 years old now.
That was a Black Friday deal from Costco, at the time.
Try to find any deal on anything "Black Friday" these days. Times have changed.
And don't let "Omen" fool you. It's a monitor, nothing more.)

Did you format this drive, or did it come preformatted with NTFS?

It's fine to leave the USN Journal with a maximum size of 1024 KB.



If you would like to change to the standard sizes:

• In Everything, from the Tools menu, click Options.
• Click the NTFS tab on the left.
• Select your T: drive
• Change maximum size to: 32768 KB.
• Change allocation delta to: 4096 KB.
• Click OK.

Please note: The maximum journal size will not actually change until the next USN Journal trim.



Other applications can also set the USN Journal size.

Did you format this drive, or did it come preformatted with NTFS?

New drive, so I would have formatted/partitioned it.

Now my "system partition", E:, is very small - perhaps only 90 GB?
(I keep nothing there, only the OS itself.)
No, that's not going to be it.

This is from a different computer, & it too "came up with" a 1024.
This is a SSD & I would have also formatted/partitioned it.

[void]

Everything will never create a USN Journal with a maximum size of 1024.

This USN Journal is either being created by the OS or another program.



If you find Everything rebuilding the index for your C: drive after a reboot, please consider increasing the USN Journal maximum size to at least 32768 KB.

Otherwise, there's no harm in just leaving the maximum size as 1024 KB.
