What is the max TBW rating for the SM841N?

Block Image

I have a Samsung SM841N mSATA SSD I got in a pile of parts, and while it works it has 20.61 TB written so far to it. This is rather high for an SSD, but for a older SSD it’s probably not too unusual.

However, I need to know the max TBW before it “expires”, if you will so I can get an idea of how used it was before I got it. My application isn’t one where I can’t take chances since I just use it as a music SSD (although it only has 27GB left) and the files are on another drive I keep as a backup, so I do have them elsewhere.

It appears the SM841N mSATA was an OEM part for Dell based off the 840 Pro series SSD. Using Samsung’s warranty data for the 840 PRO series, they could be warrantied before 5 years or 73 TBW. If i were to give a conservative estimate you are sitting at less than a third of your SSD’s TBW.

The answer can be derived from the information you have already. 20.6TB has been written leaving an amount which equaled 82% of the max TBW. It means 18% of the max TBW is 20.6TB. Hence, max/100%TBW is 114TBW.
