Western Digital pulled back the curtain on a few new portable storage products at CES, including a faster version of its SanDisk Extreme PRO Portable SSD drive and a new WD MY Passport GO rugged SSD drive.

The new SanDisk Extreme PRO drives are expected to ship in the Spring and will bring data transfer speeds of up to 1GB/s thanks to their USB 3.1 Gen 2 interfaces. They’ll be sold in 500GB, 1TB and 2TB capacities and are dust and water resistant. Included Secure Access software lets you password protect folders on the drive to keep unwanted users from poaching your goods. Pricing wasn’t announced.

Also due later this year is the WD My Passport Go drive. Available in 500GB and 1TB capacities, the SSD drives sport an integrated USB 3.0 cable and a rubber bumper to protect them from accidental drops. The drives deliver transfer speeds up to 400MB/s and are formatted for Macs and PCs out-of-the-box. Like the Extreme Pro, the My Passport Go will offer password protection capabilities. Pricing wasn’t announced.

Finally, WD also showed off a prototype USB-C drive with a capacity of—wait for it—4TB. It will be the world’s highest-capacity USB flash drive when it materializes. No word, though, on when that will occur.
