If I need storage now and I can't get flash disks, I will buy mechanical. Production will not ramp up overnight (or at all - there is no point investing in scaling up if I think the situation is only temporary), so an increase in demand inevitably will result in prices going up.

Btw gas goes up when oil goes up not just because it can replace it in some applications, but also because it is often produced and transported in the same areas as oil, by the same companies involved in oil, so it is typically affected in similar ways.
