I assume they're talking about averages here. Given that drives are at 300 GB maximum now (not sure of the average-maybe 100 GB?), doubling in capacity in the space of 3 years doesn't seem like that much progress. We were doing that in a year until recently. Of course, if the average drive is 500 GB by 2007, then that means we will have broken the magic 1 TB barrier on the high end.
A fairly recent storage white paper from a year ago (data circa 2002, I'm assuming) showed that the "average" hard drive capacity of a new hard drive to be a whopping 40 GB. Hard drive manufacturing counts with >100 GB capacity was, if I recall correctly, a paltry 4% or 5% total across the whole industry (SCSI and ATA).
I'll go out on a limb here and predict that by January of 2007, the largest hard drive will be just under or right at 600 GB, with the crowd occupying the 400 GB to 200 GB range, and the *smallest* being 100 GB. This is assuming 200 GB platters by then.
However, I'll also predict there will be a
much greater move towards standardising on the 2.5-inch form factor than on pushing capacity upwards on 3.5-inch drives. This new storage density will spawn smaller drives. 3.5-ich drives will be relegated to higher-end storage. Of course,
everything that's new will be connected to a serial data channel by then.
