Tests have shown that 256GB has a better performance over the 128GB version, I am wondering if there's a significant difference between two products
 
The read speed of a single 128GB matches the read speed of a single 256GB drive (~355MB/sec), whereas there is a significant difference in write speeds between the two drives (140MB/sec vs. ~230MB/sec).

This is mainly due to the number of memory chips in the 256 vs 128
