Corsair EX400U (1 TB)4.4
$140The SSD Review highlighted the Corsair EX400U's exceptional performance, noting it can reach 4GB/s read speeds on Thunderbolt 5 systems, though it cautioned that motherboard implementations often limit USB4 speeds. PCMag's Tony Hoffman praised its unique magnetic Magsafe connector, which allows the drive to securely attach to metal surfaces like the Corsair 6500x case. While the build quality is commended for using Phison controllers and KIOXIA memory, reviewers noted that users must ensure their host device supports USB4 to avoid significant speed bottlenecks. This drive is best suited for users with high-end USB4/Thunderbolt setups who value secure physical attachment, rather than those relying on standard USB 3.2 ports.
