If you’re booting in BIOS mode on a sub-2TiB disk, it’s probably best to stick with MBR, simply because there are some BIOSes that don’t react well to booting from GPT disks. Such problems can usually be worked around, but it’s easier not to run into the problems in the first place.

LBA is a particularly simple linear addressing scheme. Blocks are located by an index, with the first block being LBA=0, the second LBA=1, and so on. The LBA scheme replaces earlier schemes which exposed the physical details of the storage device to the software of the operating system.
