^^ We've talked about using external USB->SATA SSD in the most excellent ugreen cases in prior threads.
This does several things: it delivers a good SATA interface on a reliable chipset. Don't just buy any old USB->SATA unit. It takes the heat of the thumb away from the router and more importantly, the flash NAND in "thumb drives" is some of the lowest quality NAND being fabricated. It will fail far sooner than anything in any SSD from the last few years. (I'm not a fan of the quad packing units) USB stick NAND is
not designed for repeatedly high write activity. It will also get very hot due to the limited surface areas and heat is the #1 way to kill electronics.
Search around - there are a couple threads where we've talked about this one. I ended up taking my 80GB Intel SSD from 4-5 years ago, putting it a ugreen case and have not had any trouble in 4+ years now. Several other posters echoed the same. But if you don't have an old unused good SATA SSD sitting in your toy box, then maybe the most current and higher end USB keys will suffice. Plenty of posters are using them too. I defer to their guidance on this point! YMMV. Stay safe, stay alive!
Edited 01 Jan 2021 - I do not have experience, nor have I done any "indepth" research into the newer "NVMe USB cases". I don't have any NVMe in my junk pile yet.... Let's open a thread when we have some good info on reliability of the
cases. NVMe's can get cooking hot if you push'm so cooling is a key factor. I see UGREEN has a couple of NVMe cases now with ++ reviews. UGREEN talks about the cooling element (all AL+ the ASM2362 chipset) so I'd sure start there if I needed to buy one.
