Freeware Hash & CRC hash calculator uses native code to calculate hash values. Depending on complexity of hash functions and hashing algorithm implementation, some hashes are slower; some hashes are faster.
Time to compute hashes will differ depending on PC speed (CPU, HDD/SSD, RAM, etc.), while the relative speed will remain the same.
The following results were tested on Windows 7 Ultimate 64-bit.
CPU: Intel i7 950 3.05GHz. SSD: PCIe OCZ RevoDrive 3. Test file size: 4,427,087,872 bytes.
