Disk partitioning

Partition tables:

• MBR
• GPT

Partition utilities:

• fdisk - My preference, more feature complete and defaults to MiB, GiB, etc which seems like a no-brainer to me...
• parted
• gdisk - Nice if you only care about GPT... basically GPT fdisk, all the same syntax. Why limit yourself though?

Logical Volumes

• LVM
