You can get the same corruption on ssds if power draw is more then pi allows or if power goes down.
With an SSD you are increasing power consumption on USB which is limited to around 1.2A or however much power supply allows.
Note: I havent had any corruptions past year on pi3... all I changed was power supply, sd card and using aarch64
- wtallis 6y agoPresumably using an enterprise-grade NVMe SSD with power loss protection capacitors would avoid such trouble. Some of those have reasonably low power consumption under load, but they're all bad at idle compared to client/consumer SSDs. But now you also have me wondering about Intel's Optane cache SSD modules, which like enterprise SSDs don't have any volatile caching, and they're also cheap enough to make some sense in an RPi context. I'm tempted to do some voltage margin testing on one to see where it browns out compared to a typical consumer SSD.
