Hash rate can be defined as the number of calculations performed by the hardware in one second. This rate is of high significance, as the higher the hash rate number, the faster the calculations, which will close the block and reward you much quicker. Miners keep a look-out for a particular output from the hash function. For the hash functions, the same output is generated for the same input, yet they have been fabricated to show erratic behavior. Thus, miners try several random inputs to find a particular output for the hash function. You should understand that the competition in mining is robust, so to obtain a reward, a miner needs to search through all the random inputs as fast as possible. Thus, a higher hash rate facilitates faster search output – thus increasing the probability of being rewarded. To measure hash rates, we use the unit MH/s (megahashes per second), GH/s (gigahashes per second), and TH/s (terahashes per second). You may have already seen these units displayed above, but now you understand their importance. Furthermore, a hardware’s hash rate is particularly fabricated for Bitcoin mining, which can range from 336 MH/s to 14 million MH/s.
