Or, for the techy detail and practical advice, the first enclosures which make use of USB4 and are faster are based on a ASMedia ASM2464PD controller chipset.
USB4 ASM2464PD SSD ENCLOSURES [1]:
These enclosures sustain higher throughputs compared to older Thunderbolt 3 designs which reserved bandwidth for DisplayPort and legacy USB. Real-world peak throughput is ~3.1-3.8GB/s with the latest Gen4 M.2 NVMe SSDs. Many enclosures since 2020 are marketed as “USB4 compatible” but are based on the older Thunderbolt 3 chips, so you need to pay attention to the fine print.
