Sony is releasing a series of ultra-tough, high-speed external SSD hard drives. They are waterproof to IP67 standards, and the high=performance SL-M series offers read/write speeds of up to 1000MB/s, while the SL-C has 540MB/s read speed and 520MB/s write speeds. Available in 500GB, 1TB, and 2TB storage capacities, they have USB-C connections.
Cinema 5D has posted an article that reminds portable hard drive users that despite the speed of the interface/connection, the actual speed it is capable of will depend on the slowest component. For example, Thunderbolt 2 protocol allows for 20 Gbps but even the fastest solid state portable drives do not achieve anything like these speeds.

Powered by a six hour battery 20 hours standby), the My Passport Wireless is available in 500GB, 1TB and 2TB versions and users can offload memory cards and then send the images via wifi.
