HDD Units Down, Average Capacities Up

While the decline in HDD shipments for client, consumer electronics and performance HDDS will likely continue, increases in SATA near-line HDDs as well as external HDDs used for backup and archiving will increase, since the amount of data needing to be stored at low costs, but not needing the higher performance or latency increases. This provides some growth potential for HDDs, assuming that they can keep their areal density increasing by at least 30% annually.
