SSD Flash Memory - MLC, TLC, and SLC

What's the difference between SLC, MLC, and TLC SSDs?

[lordjeferson]

I ran to check my ssd to see what kind were, fortunately all are MLC ...
Today I learned something new, I appreciate your work thank you very much!!!

Not long ago, I purchased a Sandisk SSD Plus 1TB SLC for my Dell Optiplex 7010/9010DT; after watching this video, I realized I hit a Home Run on the first pitch. I also upgraded the RAM to 16GB Kingston Hyper-X Fury; which paired with the Sandisk SSD Plus 1TB SLC, make a lethal combination as to speed, performance, and reliability. Thank you for the information. :)

It's important to remember that the longevity of a NAND Flash is heavily dependant on the controller it is coupled with. Be sure to check your SSD or storage device and see what controller is used as it is what is responsible for complex algorithms such as error correction coding, wear leveling and garbage collection.

This video lasted longer than my TLC SSD

lol I often watch one of these before reading the relevant chapter in my OS textbook. These videos serve as a good introduction.

I'm glad you dropped the fast as possible caveat. I really absorbed the info you presented in this episode and it all made sense. Thanks Linus!

[jameseverett]

Well done! Good, clean explanations, avoiding the unimportant details we have to wade through on other channels.

I don't know why but this video is going to blowup in everyone's YT Suggestion

[SCRedstone]

omg I was literally just wondering about this when this video appeared on YouTube.
Thanks, Linus!

Actually, you don't need to perform more writes on MLC or TLC flash to store the same amount of data. The reason NAND flash wears out is electrons getting stuck in the floating gate, and skewing the output voltage of the cell. The moment the controller can't distinguish between a 0 and 1 because of this, is when the cell is worn out. Think of a NAND cell as a glass, and electrons as water. in SLC flash, the glass will be either empty or full. in MLC, there will also be empty and full state, but there are also 1/4 and 3/4 full, so 00 = empty, 01 = 1/4 full, 10 = 3/4 full 11 = full. Same principle applies to TLC, but with 16 levels. Now, let's say that instead of water, there is vodka in the glass, and you must drink it every time you determine the binary value in the glass... You can do that for much longer when you just need to see if the glass is empty or full, then with a glass that can have 16 different levels.

Dude you're so good with these videos! Always leave me well informed and entertained. Please don't stop, keep it up!
Cheers!

Surely MLC (Multi Level Cell) should be renamed DLC (Double Level Cell) Just for the sake of simplicity.

Every one of these videos I've ever seen has been clear, entertaining, and useful. Subscribed

One of the best Techquickie videos of recent times. Very informative and useful.

2 years later, still super useful. Still contemplating that cheap 3d TLC SSD for $30.00

thanks for the video, my wd Black M.2 health dropped 1% in just 144 days and i was looking for info to replace it, and found your video

[PierreAndersson]

Great video. Thanks for that. I bought my Samsung 840 Evo 500Gb 2, 5" ssd new for around 198$ in Sweden in 2014 and have used it regularly since then and still works great. Today i bought a SSDSC2BX012T4 Intel S3610 1, 2Tb for 113$ and it has been run for only 18 hours and only a bit more than 1 Tb of data have been written to it. So it's practically new. And my Samsung SSD is TLC while my Intel SSD is of the much better MLC.

Techquickie is a teacher in computertechnology, thanks again and kind regards.

The way he introduced Lynda was smooth.
