WebOct 21, 2015 · If you had an algorithm that could compress your data by 25% for an effective 125mb/s write speed, you would have 24 cycles per byte to run it in and it would basically be free because the CPU wouldn't be doing anything else anyway while waiting for the disk to churn. 24 cycles per byte = 3072 cycles per 128-byte cache line, easily achieved. http://ross.net/compression/patents_notes_from_ccfaq.html
