Hi everyone! I found a seller in my city offering a 2TB NVMe SSD (model SN720) but I'm a bit concerned about its longevity, especially since it's used. I've uploaded some info from CrystalDiskInfo, and I'm particularly anxious about the total hours and read/write issues. Could you give me some advice on whether I should go for it or not? Sorry for my English!

Good news! SSDs mainly wear down from writes, not reads or total hours. The SN720 has a rating of 500 TBW (terabytes written). From the info you shared, it looks like this drive has around 100TB of writes, which means it’s only about 20% used.
Actually, you're right! The 2TB version does have an endurance of 1600 TBW. This drive has about 104 TBW used, which is just around 6.5% of its lifespan.
No need to worry about your English, you're doing great!
What’s the asking price? Generally, buying used drives isn't the best choice since they often cost around 90% of the retail price.
The seller wants 100€, while new ones are about 175€ on Amazon for similar brands like Philips; Lexar's a bit more around 200€.
Thanks for the info! I thought the 2TB version had a TBW of 1600, but I might be mistaken. So, given that, this one has really only used about 100 TB? That sounds promising.
