This thread makes me LOL.
Only because, I started a similar thread once about a friend of mine, that I had given some Adata UV128 Yellow/Black USB3.0 flash drives to (maybe it was the Blue/Black model), and it failed on him, after like 10 total re-writes (ISO boot images).
So he swore off all Adata products after that.
I tried to tell him, WTF do you expect, these things are disposable, like a cheap ball-point pen, these days.
And then someone in the thread I started chimed in, "My old Flash drive has been working for 10 years just fine! I expect all flash drives to last 10 years! There's no reason not to!".
Completely oblivious to the changes in technology and the market, that caused older flash drives of that era to be mfg'd with SLC or MLC flash, and they were rather kind of pricey, so they could afford to do that. Compared with the market today, they're using the cheapest, lowest-grade, TLC, and soon if not already, QLC, with controllers that sometimes don't even get their firmware properly flashed at the factory. Such is the life of lowest-common-denominator mass-production and cost-cutting.
Sure, some "branded" Flash drives may well give you better results: SanDisk, Kingston, Verbatim, Samsung. Others, good luck. I buy in bulk cheap, and don't use them generally to store anything permanent. Just for temp file transfers and temp storage between machines, mostly. Like people in this thread said, they are basically "disposable", and the data on them should be treated as such, IMHO.
Get a NAS with RAID, heck, get two NAS units, identical, and set them to mirror each other. Then back up your system over the network to the NAS. Even, backup your NAS to large external HDDs (10TB EasyStore for $159.99 at BestBuy.com as I write this.) at regular intervals.
Edit: To add, I don't really use "a USB flash drive" for storing my personal data, and writing and re-writing it every day. I instead, use them mostly for install images / ISOs / bootable Live USBs, Macrium, Windows 7 and 10, Linux (all kinds of flavors), etc. So most of mine don't really fail that often, more often than in-the-field failure is simple DOA for me. Also, I've found that certain batches of Adata flash drives (the ones I purchase the most of, because Newegg has them constantly on sale, in different flavors), sometimes require an "NTFS FULL FORMAT", before writing them with MS Media Creation Tool or Rufus. Reason being, that MS MCT is very intolerant of any errors on the flash drive that you're using, and sometimes new drives need some bad sectors mapped out, which a "FULL FORMAT" should do.
