Most likely will drop further in the coming months. I couldn't wait any longer as my 2TB 860 EVO is out of space, so I pulled the trigger on the 4TB. With the cash back, this puts it around the same price as the 4TB Crucial MX500. Not crazy slick, but pretty decent.

Fill up a shot glass. You can easily and quickly see if it's more than half full - Single Layer Cell (you can represent 0 and 1)
Split the shot glass into 4ths (00 01 10 11). Try to fill it up to 3/4ths to represent 10. Takes time right? MLC or Multilayer Cell
Split it into 8ths that's TLC, the most common compromise
Split it into 16 so you can represent 0000 all the way to 1111 that's QLC. It's going to be hard and slow to fill it up to a certain point or read where it is right? Drawback #1
When you write to a cell in flash memory, you don't just put more or take off some voltage. You hit that thing with high voltage (it's based on EEPROM, electronically-erased programmable Read-Only Memory.. ROM's advantage is persistent or "non-volatile" memory).
Say you have measurement lines on your shot glass to make it easy to read how much you got. You want it at 9/16ths instead of 8/16ths, you don't just put a couple of drops, you rinse the whole thing with bleach and then fill it up to that point. Over time those lines are going to fade and you'll lose that cell. Don't worry, you'll have extra shot glasses (overprovision) but not an unlimited amount. And you'll also have to rely on those measuring lines way more when you've split them into 16ths than 8ths. So lowered longevity for QLC which is drawback #2
TLDR: do not get QLC if you can afford TLC

Some threads however, like this one, make no mention of such things and - gasp - provide good insight on evaluating the deal, explaining options for better value, talk about the market generally, and share meaningful experience with people actually interested in the product itself and its application. I can't get this deal, but I got enough information to understand that I will see it or something like it in the not too distant future where I can get the deal, which is a fine consolation.
