Speed turned out to be an important factor in choosing a hash or a checksum algorithm, so I did some benchmarks on a 1GB in memory dataset to see what the throughput will be. The CPU used was a 2.83GHz quad core xeon. These are the results (in megabytes / second):
SHA256: 115.89
SHA512: 179.65
SHA1: 310.59
MD5: 467.58
CRC32: 903.8
Adler32: 1316.2
