Compressible data is data that shrinks in size when lossless compression is applied, opposite to incompressible data which does not does not shrink or grow in size when compression is applied.

The LAMD LM87800 6Gb/s SSD controller handles compressible data very efficiently, and the ATTO test illustrates its best case behavior nicely. On the next page we will see that performance does not drop much even when it comes to dealing with incompressible information.

The read speed of Neutron GTX 240GB is impressive, topping out at nearly 557MB/s, while write speed is very close, with nearly 503MB/s.
