Question Is my SSD dying or is it just an error? CrystalDiskInfo is showing it at 1% life

[Thano22]

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

Smasung Magician results and S.M.A.R.T Log:

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

Size does affect the TBW rating....for whatever it is worth. The 500 GB version of your 120 GB drive has a TBW of 100.

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'll start to backup the data

Just a note - This should be done routinely, automatically, and all the time. Not just when there is a perceived problem.

Drives can die suddenly and with no warning.

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.
