If dell ups the price then its sales will go down.
The following seems silly:
"It's apparent, though, that to get a greater share of total disk storage revenues Dell will have to sell a great deal more storage and/or raise its prices."
If Dell holds its current pricing scheme it can take advantage of increased market share, more sales opportunities, services and etc.
Great advantage with the current pricing is that people seem to like it. Everyone any their dog wants to buy the best value they can, if Dell are offering this at cost to profits then the low margin may help over the mid to long term.
