There are no details on what this portable SSD would cost, but the 1.92TB SansDisk Extreme 900 Portable with 2TB can be bought at a discounted price of $279, normally available for $499. Last year WD showed off a similar prototype portable SSD with a 4TB capacity.
With so much capacity, data transfer speeds are also going to be important. The 8TB prototype features USB speeds of 20Gbps using the SuperSpeed USB protocol, according to WD.
The possibilities of having 8TB at your disposal to offload photos and videos without the cloud are tantalizing, but there are no details about when this prototype might become a product available to consumers.
However, SanDisk has launched a new 1TB thumb-drive, dubbed the 'Ultra Dual Drive Luxe USB Type-C' storage device that connects with smartphones and laptops.
The Type-C USB 1TB thumb-drive costs $250 and can be reserved now. It is scheduled to be available in the first quarter of 2020. The device is compatible with most Android phones, Windows 10 laptops, and MacBooks, but not the iPhone.
