I read that post as well but unless im missing something they got it backwards. Everything I've read says the opposite, that you use SLC (aka TLC) when reliability isnt important and with the fact in mind that they have a very limited lifespan when constantly being written to. Geovision is the company I quoted in my post and they specifically say NOT to use TLC. I didnt even know what SLC was until I looked it up...but after reading more I also think things are different between flash cards and flash drives, which are similar but not the same. So I guess he could be right if hes referring to SSD drives but not flash cards. I didnt research it enough to know if im correct but from what I read that's how I understand it.Single-level cell (SLC) and multi-level cell (MLC) Flash memory
First off I did not know there was a difference or a choose in technique, had enough to understand the choose in speeds, Right! SO thanks for the input.
MLC Flash devices cost less and allow for higher storage density.
SLC Flash devices provide faster write performance and greater reliability, even at temperatures above the operating range of MLC Flash devices.
These factors make SLC Flash a good fit in embedded systems, while MLC flash makes it possible to create affordable mobile devices with large amounts of data storage.
In order to select the right Flash memory for an application, it is important to analyze the how it will be used.
For example, product developers integrating memory into a portable barcode reader will most likely need SLC Flash since performance and durability are important.
On the other hand, a company building a portable media player will need the low cost and high density of MLC to price their device competitively.
