USB 3.0 Pendrive recommendations

Hi. I use CoreELEC 20.5-Nexus, Dune Homatics Box R 4k Plus with USB 3.0 Pendrive KINGSTON DataTraveler Exodia M 64GB. The system takes over 30 seconds to boot from power off mode and sometimes the CE menu slows down. What are your experiences with USB pendrives? Is it worth investing in a much faster one? Any recommendations? Thanks.
