Yes their failure rates are usually a bit higher, but usually less than the increase in rate from using more than one disk instead. A bit of math can be done using Backblaze’s disk failure rate data to get a reasonable approximation of the overall risk of failure.
You’re assuming that the failure rate for drives are all the same though. Aren’t the failure rates for new high capacity drives typically higher?
