I do agree the mining rate is slow however if you have a cheap source of hard drives it can be profitable in the long run as it is only a one cost (Unless of course the unlikely event of hard drive failure, which can often be resolved for free if you have warranty on the drive).
It may not be as profitable but it is definitely a cheaper alternative for people who have little investment so far in blockchain technology.
