                            It's time to pick a winner. What is the difference between Samsung M4 70T2864QZ3-CF7 1GB and Samsung M4 70T5663QZ3-CF7 2GB? Which memory is faster? Determining it is quite simple - look at the comparison table. The memory with lower latency and higher read/write speed is the winner.
