Professional reviewers note that the ZX20's NVMe-based design and USB 3.2 Gen 2 interface place it on par with flagship portable SSDs, highlighting its impressive read/write performance and excellent price-to-performance ratio, while cautioning about potential thermal throttling and limited long-term reliability data.
