To detect random corruptions CRC is good enough. MD5 has the advantage that it is much harder to fake by an intelligent attacker but that does only matter if you're paranoid, resposible for preventing industrial sabotage in your company, or have a computer savvy little brother who might be planning to replace your hentai collection by Pokemon episodes while retaining the checksum. 
Oh, and md5 is not slower. Reading the file from HD is the by far most time consuming process. |
MD5? Are you insane? Change to SHA512 before it's too late!!!
