Western Digital has unveiled its new 22TB CMR and 26TB UltraSMR hard disk drives (HDDs) which are now being tested by select hyperscale cloud customers.

The reason the storage giant has been able to significantly expand the capacity of HDDs over the years is due to its ever expanding technology portfolio which includes its unique OptiNAND technology, energy-assisted PMR (ePMR), triple-stage actuator (TSA), HelioSeal and now UltraSMR.
