Hellou this is Samsung 850 PRO smarty table.
```
$ smartctl -a /dev/sdh | grep -E 'Wear_Leveling_Count'\|'LBAs'\|'Model'\|'Number'\|'Firmware'
Model Family: Samsung based SSDs
Device Model: Samsung SSD 850 PRO 128GB
Serial Number: S24ZNXAH21XXXXX
Firmware Version: EXM02B6Q
177 Wear_Leveling_Count 0x0013 002 002 000 Pre-fail Always - 5887
241 Total_LBAs_Written 0x0032 099 099 000 Old_age Always - 62578693422
```
I used calculator `https://www.virten.net/2016/12/ssd-total-bytes-written-calculator/` and put raw LBAs value (62578693422) in it. The result is: 29.14 TB.
I looked up in specs and find out that:
"Samsung's 3D V-NAND technology is built to handle 150 Tera Bytes Written (TBW) for 128GB"
So it's 1/5 part of its wareout.
So why the "Wear_Leveling_Count" is so low? How to interprate this? Are these parameters depends on each other or not?
Is this disc is junk right now or not? Does smartctl reads this values in good way?
