ProGrade’s New PG10 Portable SSD

ProGrade Digital has rolled out a hefty new addition to its PG10 External SSD lineup, a 16TB version that now holds the title of the highest-capacity USB 4.0 bus-powered drive on the market. The PG10 line is designed to balance speed and compatibility. While Thunderbolt drives can be faster, USB 4.0 offers a wider range of support across Thunderbolt 3 and 4, plus older USB-C standards, so you’re less likely to run into issues on different machines.

ProGrade says the drive can hit read speeds of up to 2,500 MB/s and writes up to 2,000 MB/s. In real-world testing, the new 16TB model leaned more towards faster reads (around 2,168 MB/s) but a bit slower writes (around 1,559 MB/s). Even during long transfers filling the entire drive, it stayed warm rather than hot, something not all high-capacity SSDs can manage.

Physically, the 16TB version keeps the same design as the smaller models, including a dual heat sink setup for cooling. There’s also a magnetic base and an included metal plate so you can fix it to a surface. ProGrade also claims the unit is shock and x-ray proof, adding to its durability. Of course, 16TB of solid-state storage doesn’t come cheap, the PG10 16TB is priced at $2,999.99.
