I use an external 4TB SSD and try to format it with the smallest possible Cluster Size. In the Windows Format Dialog the smallest Cluster Size is 256KB:
When I format the disk with 256KB and also check the Cluster Size via Powershell:
PS C:\Users\Someone> (Get-Volume D).AllocationUnitSize
262144
Files still use 1MB of space instead of 256KB:
Someone know how to change the Cluster Size to a smaller Value then 1MB ?
I also tried other Cluster Sizes:
format D: /FS:exFAT /V:Samsg_4TB /Q /A:4096 // Becomes 1MB per small File
format D: /FS:exFAT /V:Samsg_4TB /Q /A:64K // Becomes 1MB per small File
format D: /FS:exFAT /V:Samsg_4TB /Q /A:128K // Becomes 1MB per small File
format D: /FS:exFAT /V:Samsg_4TB /Q /A:256K // Becomes 1MB per small File
format D: /FS:exFAT /V:Samsg_4TB /Q /A:512K // Becomes 1MB per small File
format D: /FS:exFAT /V:Samsg_4TB /Q /A:2M // Becomes 1MB per small File
When always checking the Cluster Size with (Get-Volume D).AllocationUnitSize
it's always correct corresponding to the set Cluster Size with the format
command but the resulting small Files Size is always 1MB.
When I duplicate those small some bytes Files it fast results in huge Memory wastes:
I wonder when I use another Computer and check the File properties they are correct:
