Hello,
I just ran CrystalDisk Info and the result showed my SSD at "Caution 1%" but Samsung Magician status is "Good" could it be a mistake? I remember last year it was at about 60%, it just seems weird it died so fast

CrystalDisk Info:


For example my other SSD is still at only 17% used with double the TB of data written so 82% of lifespan left:
 
The 120 GB capacity Samsung 750 has a TBW of 35 and a warranty of 3 years. The TBW is quite low for an SSD.

Those power on hours total the equivalent of 24/7 operation for almost exactly 3 years. Have you owned it over 3 years? If yes, it is out of warranty.

52 TB written is probably above average, but not outrageous.

I would be cautious and would be sure to have backups of whatever it contains.

Alright, thanks for answering, I'll start to backup the data and when I can I'll switch it with a newer one, i was looking at the Samsung Memorie SSD 870 EVO (500gb) seems like the lifespan is much bigger
Thanks again
 
All other things being equal, I would think that doubling the capacity of an SSD should double its TBW rating. That's because the number of P/E cycles would be halved.

The Wear Levelling Count is 3079. Assuming this is an average value, this would mean that the total NAND writes would be ...

128 GiB x 3079 = 423 TB​

Since the total host writes is 54TB, this would suggest that the firmware has achieved a Write Amplification Factor of around 8:1. That's extremely inefficient. A good SSD would be close to 1:1, or at least less than 2:1.

I should point out that exceeding the TBW only means it can no longer be counted on to retain data for a year unpowered at 40deg C (the standard for non-Enterprise, consumer drives). It should still be perfectly suitable for use as a scratch disk or other temporary storage esp if never powered down for very long. AFAIK only Intel bricked their consumer SSDs into read-only mode when TBW was exceeded.
