[SOLVED] sandisk ssd plus vs ultra what is the difference?

Solution
SSD plus is dramless and has a variable build of materials which means its components selection, and therefor performance, can & does vary. It's been seen with MLC as well as TLC flash and tied to a few different controllers. These are budget drives.

SSD Ultra is probably Sandisk's top Sata drive. It's a drive that does have dram and using 3d TLC flash with performance just below an Mx500 and Samsung 860 evo, especially in random performance.
