Seagate chief Steve Luczo talked down the effect of the new MacBook Air's all-SSD mix this week in a question and answer session following its latest results. He acknowledged that the designs would be "obviously pretty competing" but noted that SSDs were still in the minority at Apple, which he estimated sold just five percent or less of its Macs with flash storage. He also reiterated common problems with SSDs, such as their high prices, low capacities and tendency to bog down over time as they fill up and lose efficiency.
