I'm not sure I'd use dd in this case. If he's moving from an HDD with a 4K block size and a 4K file system block size to an SDD with a 16K physical block size he might want to consider changing the filesystem block size to 16K which should help on the write amplification side. Maybe dd can do that but I wouldn't think so. And I don't know that formatting ext4 or some other FS to 16K really helps the write amplification issue but it makes sense to me to match the file system blocks to the underlying flash block size. Real speed testing would be required to ensure reading 16K blocks doesn't slow him down though. Just a thought, Mark
