Western Digital has announced its first external SSDs to be sold under the WD brand. The My Passport SSDs are shock resistant, support hardware-based AES-256 encryption, use USB 3.1 Type-C at 10 Gb/s and promise to offer up to 515 MB/s transfer rates.

Western Digital does not disclose too many details about its WD My Passport external SSDs, but only says that the family includes models with 256 GB, 512 GB and 1 TB capacities. From the rated performance point of view, the WD My Passport seems to be faster than many other external SSDs that typically come rated for ~450 MB/s read speed, but real-world performance will need to be tested.
