SLC seems to be going away pretty quickly, if it hasn't already been phased out. It just can't produce the price / GB of the better tech. Also, that article you linked is almost 10 years old.

You're best bet for long-term reliability is to buy much more capacity than you need and try not to exceed >50% capacity for high write frequency situations. I keep an empty drive around to use as a temp directory for compiling, logging, temp files, etc.

Also, my understanding is that consumer-grade drive need a "cool down" period to allow them to perform wear leveling. So you don't want to be writing to these drives constantly.

I recently bought an external 32GB SLC SSD (in the form factor of an USB pendrive). Its random read/write speeds are quite insane (130+ MB/s both) while consumer SSDs like the Samsung 850 Evo barely manage 30 MB/s read/write. It's also advertised as very durable.

I plan on using a couple of those as ZFS metadata and small block caches for my home NAS, we'll see how it goes but people generally and universally praise the SLC SSDs for their durability.

That's likely true. I am pondering buying one external NVMe SSD for that purpose exactly.

Which brand/spec?

Vtran / eVtran. They have favourable reviews, too.

It's actually not better tech, instead it's more complicated, more error prone and less durable ways to use the same technology that produces more space for a lower price. MLC is pretty much okay but TLC is a little too fragile and low performance in my opinion. I prefer spinning HDD's over QLC since the spinning drives have predictable performance.

Some QLC drives perform quite well. And of course for any workload that is primarily reads, they're totally fine. I use one to hold my Steam collection.

Better can mean a lot of different things. From context, I was using better to mean higher storage capacity for a given price.
