Of course due to the FTL and other abstraction layers in | between, it probably didn't have the intended effect. | ugjka wrote: | I had an 8Gb drive plugged into my Raspberry pi and it managed to | kill it even without any writes happening but I guess I had not | disabled the file access time stamp updates | placatedmayhem wrote: | I do wish access times were disabled by default.

The only problem is | they are bulky, but I believe there is good reason for | that. | | Does that help? | chasil wrote: | Note that the Oracle flash drives are used, and likely | won't have the full 100k remaining lifetime. | | "This item was removed from a working machine." | numpad0 wrote: | Useful keyword is DWPD(drive writes per day) but I don't | think there are USB sticks rated that way. | ctoth wrote: | I'm using the Bar Plus 128GB plugged into my RT-AX58U to host | Diversion, a dns-based adblocker and it wasn't until recently | that I realized that Dnsmask was writing a log for every domain | resolved...

I | recently purchased a 2GB Sandisk Cruzer Titanium (nostalgia) | thumbdrive off eBay, new in package. | | Since drives at the time typically had preinstalled software like | U3 or some app to encrypt your files, I wondered if a drive as | old as this one would still be readable, never having had power | since it was packaged up. | | It was. | | https://i.imgur.com/0dNo5ni.png | | 14 years. | | It outlived nearly every CDR and DVDR I had. | holoduke wrote: | I am waiting for my raspberry pi running home assistant on a 32gb | MicroSD to die.
