When I was reviewing the PowerShell module for the New-VolumeFromRawDisk cmdlet. I saw that the alignment was set to 4,000 KiB, which although divisible by 4,096 seemed unusual. I tested and found that 4,000 KiB alignment was almost the least performant option given my conditions.

New-VolumeFromRawDiskcmdlet. I saw that the alignment was set to 4,000 KiB, which although divisible by 4,096 seemed unusual. I tested and found that 4,000 KiB alignment was almost the least performant option given my conditions.I didn't find anything very clear within the AWS documentation in general, only the EBS volumes Size and configuration constraints document.
Is there a specific benefit to using 4,000 KiB as the alignment?
