EX4 and NTFS vs TRIM and free space sharing ?

post #1 of 3
Thread Starter 
Something I have been wondering for a while now that I have not come across yet.

I will multi boot a SSD with a mix of Windows and Linux so I create small partitions to keep installations within a certain size to allow extra free space to help out with things like TRIM, garbage collection, RAISE etc. (depending on the SSD).

I am sure that I am going to make this look a lot more complex than it needs to be, but here are some things that seem contradicting.

This is what we know:
1. A SSD controller sees the drive as a whole and will spread data evenly across it to prolong its life.
2. Windows 7 writes to NTFS
3. Linux writes to EX4 (they way it is set up for me)

This is what I was wondering:

Assuming my different operating systems (Win 7 install uses about the same space as my 2 Linux distros in size), is it better to:

1. format the drive the way I do it to have more available free space for the controller to use (unused space is NTFS since both OS's can read it, in case I need it for storage)
2. format 50% NTFS and 50% EX4 (seems to make sense that each OS's TRIM would want to write to it's own FS)
3. leave unused space unformatted
4. other ?

The main thing here is to give the controller the most writing freedom to maintain performance and the life of the drive.

BTW: This can go in either SSD, Windows, or Linux section but I picked this one as Linux is my main OS right now, so I wanted it's priorities dealt with first.

With respect to TRIM it really doesn't matter how or whether you partition the drive. It works at the level of raw logical sectors. So do whatever you want. smile.gif

Thanks. I was thinking of that, but for some reason I figured there was a way for the different file systems could affect each other.

I guess if there was an issue I am sure it would have already been brought up and dealt with by now.
