I've been using some cheap flash drives for things like installing OSs and the like, but now I've picked up a Dell Wyse 3040 system to play with which only has 8gb of storage. So I'm installing the OS onto a flash drive permanently (don't worry, just for messing with, nothing of value will be lost if/when the drive craps out).

However, the performance of my cheap flash drive is terrible and installing packages & transferring files is so slow. My question is: Would getting a better drive make a meaningful difference here? If so, anyone have some recommendations of drives they like that are fast?

For running an OS off a USB drive, I would recommend getting a USB to M.2 enclosure and putting an M.2 drive in it. This will give you better performance than any flash drive out there. The memory they put into normal flash drives is just slow slow slow for the use case of an OS.

M.2 Enclosure

M.2 Drive to go in it


Now, the only negative there is that is kinda expensive. If you really want to stick to a normal USB drive, maybe try this one out. But I would really like to stress that running an OS off a normal USB drive is going to be slow.

You likely won't notice much of a difference between SATA and NVMe when using the drive via USB, and many people have spare SATA SSDs, so I'd just grab a USB to 2.5" SATA cable: https://a.co/d/dQ5QXR1. You don't need an enclosure because the drive itself is already an enclosure.

Don't pay almost $20 for just a cable, pay $3 for this. it's an enclosure you can put your 2.5in sata drive in to connect it with usb3. I have several, work like a charm https://a.co/d/8Z2VPso

USB SATA controllers are also very hit-and-miss. There's plenty of really, really bad ones out there. Either missing features, slow, getting hot or all of the above. If you found one that works well, good for you, but I'd avoid most noname brands, unless I had specific knowledge about the product or the very least the chipset they use.
