Logical Block Addressing
LBA is a method for identifying where data lives on a storage device.

- Newer computers use 48-bit LBA, allowing hard drives up to 144 PETABYTES.

- IDE:
For more issues around 48-bit LBA head over to: 48-Bit LBA
Top transfer speeds of 133 MB / sec and older hard drives were even slower.

- Serial ATA:
SATA I - data transfer speeds of 150 MB / sec.
SATA II - data transfer speeds up to 300 MB / sec.

- Future Serial ATA drives are looking upwards of 600 MB / sec.
