Question File System Question

Hi all !!

I am looking for a filesystem which allocates less than 256 bytes per block/cluster and supports at least around 2 terabytes per drive.

This can be achieved by a filesystem which either has static or dynamic assignment of block/cluster size.

If static, obviously it must be equal or less than 256 bytes per block or cluster.

If dynamic, it just needs to have a lower threshold support of, at highest, around 128 bytes. Or better yet, no lower minimum.

NTFS is an example of a file system which has a static assignment of cluster/block size with the smallest configuration per cluster/block at 512 bytes which if selected is accompanied with the decent limit of 2 terabyte per drive.

So if you know of a file system which allows a cluster/block size of 256 bytes or lower while supporting terabyte sized drives, please be kind and let me in on the fun

Thanks all!!

I think that the disks are designed with 512 bytes/track which means you cannot divide that track to smaller clusters.

Edit: I obviously meant bytes/sector.

Actually nowadays drives have 4kb sectors and have simulation support for 512 bytes sectors.

It's irrelevant though. File systems may have a cluster size smaller than 512 bytes; or even have a 512 bytes cluster that is divided over two or more 512-byte sectors.

Also if you can not find a file system for windows that allows for dynamic or static clusters under 512-bytes keep in mind that if you can find a different file system with Block Suballocating support it will serve as a perfectly working solution for my project.

P.s. the correct term for dynamic cluster size is: "Variable file block size."

in any case ty ty ty for the input
If you learn of such a file system, I will be here, refreshing the page approx. every 15 seconds lol
