Nonsense. This is true a decade ago. Not anymore. Nowadays tlc is reliable and fast enough to be what slc were back then.

Even samsung flagship 990 Pro is TLC.
WD SN850x is TLC
SK Hynix Platinum P41 is TLC

These three are the most powerful (and most expensive) ssd you can buy in market to date.

MLC is now reserved to the highest end of datacenter storage you can't find without a special procurement.

SLC is pretty much nonexistent nowadays. Go find and tell me which ssd model after 2015 that use SLC, if you can find one.

Slc is all advantage. Everything good about ssd - except it does not exist anymore, and nobody misses it.

All performant consumer and datacenter ssd now made with 3d nand, for example vnand or bics which is tlc or qlc only. The only part in your ssd that use SLC these days is the buffer, like 12gb for 1tb sn850x, and allegedly around 100gb for 990pro 1tb, but even that is just pSLC, which is just MLC/TLC running in single bit mode like SLC.

Even for datacenter use TLC is deemed more than good enough. The latest Samsung PM9xx line is TLC.
Any more performance/reliability demand they have to enter xpoint segment, like kioxia's FL6 which can go like 60 DWPD. (avg high end ssd is around 0.3 DWPD)

MLC is already at the end of phasing out stage. The last ssd that I know that were using MLC was 970pro which were released 5 years ago.

Mainstream mid/low tier drive is all qlc nowadays. But even that is magnitude better than mlc from decade ago. To put into perspective, if we look at this spec from Samsung
https://semiconductor.samsung.com/resources...English_AUS.pdf
2012s MLC 840pro were rated around 150tbw/1tb,
while equivalent 2020s QLC 870qvo is 360tbw while retaining same speed or being slightly faster.

Tldr - 'You should look for SLC/MLC' is not even an argument nowadays unless you are parroting what you have heard 10 years ago - and you won't even find it in the market anymore anyway.
