USB4 is gaining ground as an equally fast alternative to the expensive Thunderbolt, especially in notebooks. However, the range of USB4 SSDs is still quite limited. Corsair joins the ranks with the compact EX400U, the first SSD with the U21 controller from Phison. This converts the USB4 signals directly for the flash devices; the usual intermediate PCIe step is omitted...
With the EX400U, Corsair has fulfilled the desire of many media professionals for a compact and powerful external SSD. It combines a small housing with USB4 speed. And in view of the attractive price, the plastic housing is a good thing.
