the ssd has a sandforce controller with buildin compression. Sequential speeds for random data are ~200MB/s read, ~130MB/s write. 4k random data write with one thread is ~55MB/s, ~115MB/s with 64 threads. It looks like the encryption transforms the 0-data stream in a more or less random data stream.
