The SanDisk Ultra 3D is priced in between the Crucial MX300 and the Samsung 850 EVO. This matches their relative performance. The performance advantage of the 850 EVO is quite small for most real-world workloads, so its premium mostly buys you a longer warranty and the proven maturity of a product that has been on the market for a long time. If your workload is heavy enough for the difference between the 850 EVO and the Ultra 3D to matter, you should probably be shopping for a NVMe SSD instead of SATA. Meanwhile, the SanDisk Ultra 3D offers higher write endurance ratings and lower power consumption for a slightly lower price. The Ultra 3D makes more sense for most consumers.
