Huge MSPT spikes because of faulty Storage?

I am not an expert on this, but I strongly suspect that this is I/O related or a storage issue, but just to be sure I will ask here as well.

In some intervals I get some spikes in the mspt mostly between 1-3k ms, in this spark report it was even worse, but well. Is it safe to assume that this is something with the disk? Appreciate any help.
