In my experience, SD cards and eMMC chips on the Raspberry Pi Compute Modules are night and day in terms of reliability. Brand-name SD cards will fail in 6-12 months of running a typical mostly-idle Linux installation (yes, I've heard it all: power supply quality, improper shutdowns, counterfeit cards, etc. etc. It doesn't matter - SD cards just die all the time) I've yet to see an eMMC chip fail on a Compute Module. I'm aware of one Computer Module that's been running for around 3 years as a CI/build machine, so it's under a pretty write-heavy load all the time. I expected it to last 3 months. It has not died (yet).
