How to align partitions for Best Performance using parted?
Calling parted with the ‘-a optimal’ parameter and specifying a mkpart partition start of 0% resulted in parted starting the first partition at sector 65535. Although it seems odd that this isn’t a whole number of MiB, it is the first integer value arrived at when multiplying 8191.875 by 2, 3, 4 etc.
Where do you put the alignment offset in parted?
One question: alignment offset should be in sectors according to my docs (never seen the value being other than 0) – that changes where the offset fits in your formula, does it not? Or did I get something wrong? Thanks for the excellent article! -F so his (1048576 + 0)/512 version should be correct.
Which is the end of the disk in parted?
Negative numbers count from the end of the disk, with “-0” being the end of the disk. If you don’t give a parameter to a command, Parted will ask you for it. For example:

How big is a page size in eMMC?
It usually equals 0.5, 1, 2, 4, 8 MiB depending on eMMC datasheet. If you find block size alignment too much memory wasting, then stick to the page size, generally found in the range of 4..16 KiB.
How do I align my partition on my computer?

What’s the maximum data rate for an eMMC?
Legacy eMMC devices support a 0-26 MHz clock speed with maximum data transfer of 26 MB/s. They use Single Data Rate (SDR) mode to transfer data. In this mode, a single bit can be transferred on each data line per clock cycle. Later eMMC devices support a clock speed of 0-52 MHz. Dual Data Rate (DDR)
