The last few years have seen rapid advancements in flash technology including planar 1x nm NAND, TLC, and 3D V-NAND. External high-speed interfaces such as USB 3.x have also become ubiquitous. These advances have led to the appearance of compact bus-powered direct attached storage units with very high performance for day-to-day data transfer applications. We have already looked at portable external SSDs such as the Samsung T1 and T3, as well as the SanDisk Extreme 900. Today, we will be looking at Netac's Z5, a portable SSD with a USB 3.1 Gen 2 10Gbps Type-C interface.
