I got some empirical data on this! Effingo file copy service does application-layer strong checksums and detects about 4.5 corruptions per exabyte transferred (figure 9, section 6.2 in [1]). This is on top of TCP checksums, transport layer checksums/encryption (gRPC), ECC RAM and other layers along the way. Many of these could be traced back to a "broken" machine that was eventually taken out. [1] https://dl.acm.org/doi/abs/10.1145/3651890.3672262 |
