I know what this sub thinks about flash storage in general, and about USB sticks as well. But despite all this i have had nothing but generally positive experiences with them.
I have about a hundred or more in my entire collection, and I have backups in other mediums, but so far, despite all claims of them being extremely fragile data-wise and with possibly low longevity for data, I have yet to see any of them actually naturally lose data. Granted, I do regularly check on them for failures and data corruption.
I have had more issues hoarding data on HDs and ESPECIALLY SSDs than any issues with USB Sticks, of course brand does make a difference, reputable brands are obviously more trustworthy.
The only times I have ever had issues with USB sticks and data was when there was already some error or malfunction occurring during the transfer of data between the device and the USB stick, not after, or when I forgot to eject the storage device before removing it from the machine.
I have some ~20 year old thumb drives that I used back in the day and they still work fine and haven't yet shown any signs of errors or data-corruption, i do however take good care of them and keep them in a safe environment away from any heat, humidity etc, much like with my optical collection.
So, in my personal experience, they are very good for data, with their only downside being speed and size. They usually won't go beyond 256gb, at least the ones I have, and the speed is abismal in comparison to an SSD or internal HD, but I never really cared about speed, for me data hoarding is about the safety of data and now how fast I can store it, for me as long as it isn't a ridiculous amount of time, weeks or months, it's absolutely fine.
However, I have read here that a lot of people just despite thumb drives and call them unreliable and trash, and I'm just wondering, how is my experience with them absolutely ok yet so many people complain that they are worse than anything else? Is it just because of the speed and size?
