And so, I bought a disk from my hands, when connected to a laptop through my pocket, it shows 100% health
OCZ Guru also confirmed
# smartctl -a /dev/sda

You need to perform a TRIM operation or connect the SSD to Windows 8, 8.1, 10 or Linux Unix mac and perform TRIM or use the recovery utility from the OCZ website, apparently your disk was unsuccessfully erased.
Yes, you still need to install the latest firmware from the manufacturer's website! Everything will be OK!

Device is: Not in smartctl database [for details use: -P showall]

This means that your disk is not in the smartctl utility database.
In order for it to understand all the smartctl parameters, you need to update the database.
You can try
If it does not update or update but the disk does not appear, then try the script.
You must have the update-smart-drivedb script installed, it loads a fresh drive database. Perhaps your disk is there. The script should run without errors.

# update-smart-drivedb -v
Download from branches/RELEASE_5_43_DRIVEDB
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  136k    0  136k    0     0  23559      0 --:--:--  0:00:05 --:--:--  169k
/usr/share/smartmontools/drivedb.h updated from branches/RELEASE_5_43_DRIVEDB

After that run smartctl and see what happens. The message that the disk is not in the database should disappear, and the parameters should get the appropriate names.
After that, you will read the errors.
PS
I like Intel SSDs. You go to their website, "pull" the specification, read it and write a script that parses the output of smartctl and you get this more or less human response:

"The workload took 244041 minutes (169.473 days) to complete with 51% reads and 49% writes. A total of 12507.7GB of data was written to the device, which increased the media wear in the drive by 2.72949%. At this point in time, this workload is causing a wear rate of 2.72949% for every 244041 minutes, or 0.000671074%/hour"
