Use-cases differ even for storage, and cost is sometimes a competitive advantage in low-value products. While high-end SSD include onboard super-capacitors to keep the hardware stable during power-failures, larger drive ram buffers with fetch prediction, and sector sparing with wear leveling.

If your stack uses anything dependent on classic transactional integrity, than the long term hidden IT costs of cheap ssd failures don't make sense.

"buy cheap, buy twice" as they say. =)
