Samsung also include a hardware-based encryption engine. Sadly, the Portable SSD T3 isn't any more affordable than its predecessor. Over the long term, this new flash should cut the price of desktop SSDs almost in half. The move from 32 layers to 48 is more impressive than it sounds, as density went from 128Gb to 256Gb. This is the first product from Samsung to ship with 48-layer V-NAND.
The Portable SSD T3 does get a nice technology upgrade in the flash department, though. We hoped that Samsung would release a PCIe-based variant with a 10 Gb/s interface to the host, but that didn't happen. Even though the Portable SSD T3 employs USB Type-C, it operates at the same speed as the T1 with a mini-USB 3.0 connector. Samsung says all four versions are capable of 450 MB/s sequential transfers, though the drive may be limited by USB 3.0's 5 Gb/s data rate in certain situations. Inside each drive is a standard mSATA SSD with firmware optimized for external use. You'll find the Portable SSD T3 in four capacities, including 250GB, 500GB, 1TB and 2TB.
