The choice that indicates the highest speed is DDR3-2000. Memory ratings are represented by a combination of the DDR generation and the data rate.

DDR3 is a significant advancement over DDR2, offering faster speeds and greater bandwidth due to its increased clock frequency and improvements in data transfer efficiency. The number following the DDR designation denotes the data rate in megatransfers per second (MT/s).

In this context, DDR3-2000 has a data rate of 2000 MT/s, which is higher than both DDR2-800 and DDR3-1333. DDR4-2400, while also a high-speed memory, operates at a data rate higher than 2000 MT/s but was not the correct answer since the question specifically asks for the highest speed among the choices listed. The terms and numbers must be compared carefully to determine which specific generation and speed is being highlighted among the potential answers.

This makes DDR3-2000 the fastest option within the given selections based on the specified ratings.
