How can tell the difference between an MLC and SLC SSD?

This might sound like a silly question, but when I'm on retailers like Newegg and check out the bunch of SSD's they have in there, most don't have whether they're based on MLC or SLC technology.

I used to think "More $$ + Low Storage = SLC" but I don't know anymore. At least some OCZ ones which are very expensive and average space.

Maybe I can also go by the R/W speeds? But I'd still get confused with those MLC at average speeds and high $$ >.>'

Yes, it is hard to determine. For the most part you can tell by the price, MLC drives are going to be twice the cost of SLC drives(or higher).

In Newegg, look at the bottom left area of the page and click the tab for "Manufacturer Info", then click the link for "Manufacturer Product Page". You can normally find more information there.
