Which SSD model is SLC？

Basically none of the current consumer SSD's are fully SLC. They may have an SLC cache, but most will be TLC or QLC.

You would have to look into enterprise grade gear for a full SLC option.

I think SLC is mostly just adopted into Server space because it's so expensive. Even the high-end PCIe Gen4 SSDs mostly use TLC.

The Pro series of Samsung is MLC,they are crazy expensive though:

SLC is extinct.

The MX500 from Crucial is MLC, otherwise everything is mostly TLC/QLC these days with some higher-end exceptions. 

Edit: Its the BX300 that's MLC

Yep, sorry. It's the BX300 that's MLC.

I can think of two tricks to get SLC or better performance without buying a SLC SSD.

 

One is to make use of the SLC cache in SSDs. For example, the Intel 660p 2TB allocates 280GB of its capacity to SLC cache mode providing you use in total less than 25% of its capacity (500GB). If it has to be pure SLC, you simply limit the capacity of the 2TB SSD to 280GB. Looking at one supplier in the UK, this is £228. If you run it essentially in SLC mode, that works out to be 81.4p/GB, compared to 11.4p/GB if you use its full capacity.

 

The other is to consider Optane. The older 900p 280GB in U.2 connection is £299 at the same supplier I looked at (M.2 version more expensive). That would work out more expensive at £1.07/GB, but arguably it would be higher performing than the 660p in SLC mode.

 

So it depends on your capacity needs and why you want SLC in the first place, what solution might satisfy that. It's going to be much more expensive than "regular" SSDs however you do it.

The Samsung Pro series makes more sense considering the price,It's MLC but we all know that SLC is overkill,

I even have a 256MB SLC drive from 2006 (Not EMMC),It still works in the machine it was in,

The only problem with it is that one of the capacitors is dead,i need to replace it.

Again from same supplier, the 970 Pro 1TB is £318. So yes, much cheaper per capacity than trying to use a 660p in SLC mode, or Optane. We don't know why OP stated a desire for SLC so we're guessing a bit here. I have in the past considered if I was rich enough to use SSD-as-ram for a large compute job, but decided against it. That would be really punishing for cheaper consumer SSDs. A raid of older generation enterprise SSDs was looking like the best balance, but UK pricing sucks compared to US and I never followed through.

none essentially, SLC mode 2-bit MLC or TLC or QLC is what you can get. 

 

 

which gets you that sweet SLC performance untill the cache runs out
