fast data integrity check tool

[daFranze]

We are moving our data from one hpux host to another. Our auditing department asks for some checks/documentation to proof data integrity. We just double checked a md5sum check of a 25 GByte Oracle Data File takes about 45 minutes. Since we have some of them (files) and a shortage of time we try to find a quick utility to check data integrity. "checksum" is even slower than "md5sum". Are there any fast utilities you would recommend?

Compare filesizes as a fast first check.
Compare md5sums later.

25 GB/45 min is about 9 MB/s.
I doubt you'll find a much faster method.

Dank dir Stefan! Ich habe es befuerchtet, oder erwartet!?

we decided to use "sum" in our test and integration environment and use the strong check md5sum in our production environment.

to be exact md5sum is not ported for Itanium (information from hp labs), that's why md5sum is poor slow on ia64 machines, better use the cksum, which comes with the OS
