Unreliable, issues from the start, dead in 2 months
October 20, 2018
Not sure what happened with this, I used to think it was impossible to get a bad SD card, especially from a company like Kingston. Well those beliefs have been dashed, this card exhibited issues from the very beginning but since I was using it in a Raspberry PI project I've never done before, I was thinking something was wrong with my linux install. Random files would come up corrupted, but not so many that I would think something was wrong with the storage hardware. Maybe 1 out of every 2,000-3,000 files would turn up with a bad hash (large database split into multiple small files). The app was able to recover/rebuild the lost database files each time so I thought it was no big deal. Well, not even two months in service and the card now refuses all writes when in the Raspberry PI. Oddly enough, it seems to only outright reject to work when I'm using Debian formatted to ext4. If I reformat it to NTFS and use it with Windows, it seems to be read and write at normal speeds. I ordered a new, different brand SD card and it ran without a problem. In fact, much of the slowdown and all of the issues I was having with the Raspberry Pi, that I was assuming were just due to the limited hardware on the device, turned out to be due to this bum SD card from Kingston. Maybe I just happened to get a card from a bad batch, maybe these cards are somehow incompatible with the EXT4 file system. Either way, for my use case, this card is useless.
