1 Assuming 2:1 compressible data.
2 Prior to the release of ECMA-321, SLDC (streaming lossless data compression) was known as “LTO-DC.” SLDC uses ALDC as its primary data compression scheme, but also has a pass-thru scheme to avoid the expansion of incompressible data—a problem ALDC and most other compression algorithms encounter.
