Samsung's mass-market external drive, the Portable SSD T-series, was last updated in August 2017 with the introduction of the T5 with 64-layer V-NAND. The Portable SSD T5 came with a SATA SSD internally and a USB 3.2 Gen 2 (10 Gbps) Type-C port for the host interface. Since then, we have seen a number of technology updates in this market segment including newer flash generations and the introduction of NVMe - USB 3.2 Gen 2 (10 Gbps) bridge chips.

At CES 2020, Samsung is unveiling the Portable SSD T7 Touch and also announcing the Portable SSD T7. Both products place a NVMe SSD behind a USB 3.2 Gen 2 bridge to offer up to read/write speeds of up to 1050/1000 MBps. The performance specifications for the two products are similar, with the only difference being the fingerprint-based security option in the Touch version. Typically, Samsung has used external SSDs as test drivers for new V-NAND generations. For example, the Portable SSD T5 was the retail debut for their 64-layer V-NAND. Based on recent announcements, it looks likely that the Portable SSD T7 Touch and Portable SSD T7 use the sixth-generation 136-layer V-NAND.
