SLC vr MLC is on of thoses in the end doesn't really matter things. THe differnce between the too is in SLC 1bit = 1 cell on the disc, in MLC 2bits = 1 cell. Writing two bits per cell will cause that cell to "wear out" sooner. How much sooner who knows. How long with it take you to get to 1 million writes on a particular cell?
As far as random reads and writes SSD excel at them. That's the whole point of a SSD. It is able to access any part of the drive at the same time. No moving head like in magnetic media. What your refering to was that some early SSD did have any cache on them. Who needs 16MB cache the whole drive is cache was the thinking. Well as they found out cache was needed. All current SSD have cache like any other type of drive.
