Why do SSD's have problems (i.e. slow xfer rates) reading small random files?

inherent problems with parallelism with small files
This is a good overview of varying issues with small/large file and random/sequential in coding for SSD chapter here:

Even intels P3700 enterprise drive has same slow 4k random read as all other drives on market, makes it no better than Samsung 840 Evo because most desktop use is lower Q. But Samsung new nvme drive (which will have an m2 interface on mobo) will be first SSD to have significant increase in random 4k read, supposedly about 100 mb/s, ie 2.5 to 3x faster than any current drive on market, hopefully out by end of this year.
