What is the fastest way to generate MD5 code for a huge (140 GB) tar file in Fedora?

Recently I downloaded a big (140 GB) tar file and it has an MD5 code to verify the downloaded version.

I used md5sum filename to generate MD5 code and compare it with the original one. But, it seems that I should wait for a long time.

Is there a faster way to generate MD5 code for a big file in Fedora?

Solution

  • If you're not using SSD, your hard drive will be only able to read at about 30M/s.

    So for a 140 000MB file size, you have already something like 1h and a half just to read the file.

    Now add that there is some process on your computer running, i guess that your "long time" can be something like 2 hours.

    Unless switching of storage support for a faster one (SSD, USB), there's nothing much you can do.

    Now if md5sum take 10h, i guess it's possible you can find better.
