I third that. Machines are very fast today. Reliability is vastly
more important than speed in many cases. Let's say that CRC
introduces a 20% slowdown (which is probably an overstatement). This
means that, to get the same speed, we will have to spend 20% more on
the hardware. Let's say that this is a top-end server, so we have to
spend $12k instead of $10k. Is $2k worth it for better data
reliability? Absolutely! No question about it.
