Nowadays only very expensive SSDs use MLC because TLC is much cheaper.
I really like Sandisk solution they have about 10% SLC chip for most used files and 90% TLC for less popular files, this way only the SLC chip rewrites mostly. 
From second hand it's avaible for about 100 dollars the SanDisk  Ultra II 480GB. I think nowadays this is the best buy.

still . even though the ssd use tlc . there are more nand chip inside an ssd than in the flash drive . that is why ssd is much faster and have more storage than flash drive . ssd can go up to 16tb but flash drive still in 2tb
