The 2.5-inch HDD will be more prospective in coming years. It’s predicted that Worldwide shipments of 2.5-inch HDDs to all-in-one PCs are forecast to reach approximately 1 million units in 2013, up from virtually zero this year, according to an IHS iSuppli Storage Space Market Brief. So, we’re facing the the rising of 2.5-inch HDDs –more computer designers, tech marketers will watch this trend.
Currently 2.5-inch HDD is used widely in a variety of device, including mobile or notebook PCs, external HDD and servers and storage systems. Interestingly, the 2.5-inch HDD has lower power consumption and higher endurance.
According to IHS iSuppli, the shipments of 2.5-inch HDD then will increase to 3 million units the following year and rise steadily until they hit some 7 million units in 2016, as shown in the figure below. The HDD market for all-in-one PCs will continue to be dominated by 3.5-inch discs, with shipments by 2016 estimated at 31 million units, but growth will be much slower for the segment during the same period than for 2.5-inch drives.
“With a maximum capacity of 1 terabyte, 2.5-inch HDDs are proving very attractive to PC makers for use in their next-generation all-in-one designs,” said Fang Zhang, analyst for storage systems at IHS. Zhang added, multiple all-in-one PCs have the potential to adopt 2.5-inch HDDs, including the iMac from Apple Inc., TouchSmart from Hewlett-Packard, Series 7 from Samsung Electronics, IdeaCentre from Lenovo, Top Touchscreen from Asus Eee and all-in-one desktops from Vizio and Acer.
Though it has several advantages, the 2.5-inch HDDs typically run at 5,400 rpm –lower than 3.5-inch series. In the market 2.5-inch HDD is slightly more expensive.
Zhang of IHS iSupply prediceted, the 2.5-inch will represent approximately 4 percent of the all-in-one desktop PC market by next year. And as capacity and speed continue to improve and costs go down, the 2.5-inch HDD is expected to take share away from 3.5-inch HDDs in the traditional desktop PC market.
