Any number that is divisible by 8 should work as a starting sector. Though it only matters on SSD drives. For HDDs it makes absolutely no difference.

When the host attempts to write a single 512-byte logical block, the hard drive will first read the 4K physical sector containing the 512 bytes that are to be overwritten. Next, it will insert the 512 bytes of new data and write the entire 4K block of data back to the media. This process is called a “Read-Modify-Write”. The drive must read the existing data, modify a subset, and then write the data back to the disk. This process can require additional revolutions of the hard disk.
