Flash Memory Speed and Reliability: SLC NAND, pSLC NAND, MLC NAND, TLC NAND

I have never paid much attention to flash, but this page below really helps as does this YouTube video. It applies to computer SSDs, as well as to things like SDXC camera cards.

For example, the OWC Atlas S Pro SDXC camera cards use pSLC NAND, which is about 10X more durable than the flash used in many average/ordinary SDXC cards. Very few SDXC cards even quote a duty cycle, but OWC does:

7310TB total bytes written (TBW), equal to 2862 GB per day for 7 years.

All the digital images I’ve ever shot over the past 15 years add up to about 20TB. So with the OWC Atlas S Pro card, I’d need to shoot another 6990TB of images to wear the card out. I need to get myself a 100 gigapixel camera...!

SLC, pSLC, MLC and TLC Differences - Does Your Flash Storage SSD Make the Grade?

Not all SSD are created equal. There are enormous differences in ability to work at temperature, in poor power environments, under high duty cycles. When talking enormous, an Industrial Grade SSD can have as much as 300 times (yes, 300 times, not 300%) more write endurance cycles per physical block of data.
