I was wondering how the disk geometry affects SSD alignment. I was reading https://wiki.archlinux.org/index.php/Solid_State_Drives (using MSDOS partitions) and it seems to me that they are choosing a disk geometry so that the erase block size divides the cylinder size, and then they are starting the partitions on the second cylinder. That makes sense, but could I also keep the original geometry---255 heads 63 sectors/track---and just start the first partition at sector 1024, which is 512KiB after the start of the disk?
In other words, does the number of sectors per cylinder actually matter, or is the only important thing that the partitions start on the right sectors?
