Leaders in worldwide storage devices, Western Digital and Seagate launched their mobile HDD lines, My Passport Ultra and Seagate Seven, in tandem with increased sizes.

The new mobile hard disk drives come from the higher demand for backup space and auxiliary data storage availability from an increased number of mobile platform users. As the internal space on mobile phones is still kept low, increasing only incrementally from 16 GB on previous generations to 32GB on current generations of smartphones.

As HD photos and pictures tend to get higher and higher resolutions and graphic fidelity, space becomes a critical issue for the industry. In this regard the clear stand-off between the two HDD giants is based on the profile of the new released products.

Sharing the demand

Western Digital handles the demand for large storage space, upgrading its My Passport Ultra and My Passport for Mac to USB 3.0 interface and 3TB of storage space, while Seagate will take over the mobility segment of market working in tandem with its in-house Samsung HDD department, bringing its Seagate Seven line to today's standards.

Sharing the Samsung's tech for ultra-thin 7 mm height and 178g weight, Seagate will probably inherit its own patented SMR (Shingle Magnetic Recording) technology and its USB 3.0 connectivity, leaving its Samsung department to handle size with its newly launched M3 and P3 4TB external HDDs.

Although Western Digital will probably also incorporate its own HelioSeal technology on its future Passport Ultra portable HDDs, it’s all in the end just speculation as tech details are scarce around this new release. As WD's child company, HGST, just launched the Ha10, the world's biggest 10TB platter HDD with HelioSeal, we can only expect that this sort of tech will hit portable storage disk drives relatively soon.

According to DigiTimes, Western Digital's new 3TB My Passport Ultra will probably hit stores in July, while Seagate's new Seagate Seven model still has an undisclosed launch date.
