Hi Matthias, Sorry to hear about the flash drive's slow write rate. May I suggest this model specifically? https://www.westerndigital.com/products/usb-flash-drives/sandisk-ultra-dual-drive-luxe-usb-3-1-type-c?sku=SDDDC4-128G-G46 The read and write rates are great _and_ it supports TRIM via blkdiscard(8), which is great for wiping it quickly between uses without the excessive time or flash wear of manually wiping it via dd: https://man.archlinux.org/man/blkdiscard.8 I own several of them, of various capacities, and am very happy with them. You can find them on Amazon as well as many other places, and I haven't ever gotten a counterfeit. (The laser engraving on them is harder to duplicate, too, I suppose.) They come with some Windows and Android binaries preinstalled, but mkfs (or blkdiscard!) takes care of that quickly.
