As new drives with 4096b sized blocks appeared, partition alingment is becoming more and more important.
But, what I am interested in is, if I use the whole block device for filesystem (eg. /dev/sdc) - are the FS block aligned, or do I need to create a partition and align it for FS to be aligned with block device sectors?
My logic tells me that it's OK, because aligment is needed in first place because of MBR and/or partition table, which takes some space at the start of the drive. If I don't use it, my FS should be aligned by default.
Am I correct or am I missing something?
