Notebook designers are planning to add SDXC to their systems in sync with the mobile Core i3, i5 and i7 processors launching early next year, a purported leak said today. At least Dell, HP and Lenovo are believed to be engineering their notebooks to use the new card format at the same time as they switch to the 32nm processors in January. It would give the PCs recognition of cards up to 2TB in capacity and transfer speeds faster than current solid-state drives, at up to 300MB per second.
The timing of the switch is indirectly linked by DailyTech to the advanced nature of the standard. Even at the current 104MB per second, SDXC would be bottlenecked by the USB 2.0 bus and would likely move to PCI Express instead.
Other companies haven't signaled their own intentions, but multiple introductions are expected in January and will following in coming Apple may be one of the later entries as the iMac and MacBook Pro already have SD (currently SDHC) slots but have been updated relatively recently.
