All disk drives lose data. If you take the capacity and divide it by the nonrecoverable error rate you'll see that the rate for bit rot is significant.
I deal with multi-100TB arrays at work and we see this all the time. The best defense right now is a filesystem or application that uses checksums on the data, RAID6 or better and frequent background scans (as frequent as your throughput requirements allow.)
It can be done but it's not trivial.
Bottom line, with a consumer setup you will have undetected data corruption over time.
