SLC, TLC or DRAM modules
« on: November 03, 2017, 07:49:31 AM »
I just started reading about SSDs. I saw that there's a big difference between SLC and TLC, that most current SSDs are TLC and that TLC is slower and more crash-prone.

I also read about SSDs with DRAM modules and although they lose all data when the power is cut, I found them more interesting, since I use an UPS anyways. They have the advantage of unlimited rewrite, but they use more electricity.

The SSDs that are usually discussed here, are these SLC or TLC?
Has anyone here ever run OS 9 with an SSD with DRAM modules?

Some years ago I checked a few articles on that, and here's some parts of a series on them, on the durability of SSD:

They don't answer all your questions yet, but I really think you might find some information in them useful or relevant.

Fortunately, they all issued SMART warnings before their deaths.
