The gdisk man page suggests using the '-a' option to align partitions on a solid state disk:
"Align Change the sector alignment value. Disks with more logical sectors than physical sectors (such as modern Advanced Format drives), some RAID configurations, and many SSD devices, can suffer performance problems if partitions are not aligned properly for their internal data structures. On new disks, GPT fdisk attempts to align partitions on 2048-sector (1MiB) boundaries by default, which optimizes performance for all of these disk types. On pre-partitioned disks, GPT fdisk attempts to identify the alignment value used on that disk, but will set 8-sector alignment on disks larger than 300 GB even if lesser alignment values are detected. In either case, it can be changed by using this option." Is my interpretaion correct? I have a Samsung 300G SSD in the new desktop. I interpret the above as advising me to use the '-a' option when I use gdisk to create GPT partitions on it because gdisk will not automatically align logical sectors on SSDs.
