The system freezes when working with SSD, what could be the reason?

Question

Debian

Good afternoon. I recently bought an SSD (Kingston SSD NOW 240GB) and installed Debian 8 on it. Everything seems to work fine, but I can't decompress a large ~8GB tar archive. At some point, the system just freezes tightly and that's it. Free space ~160GB.
Transferred the archive to the HDD and there it was normally unpacked. What could be the problem? Is the SSD defective, or something in software?
Just in case, I attach a SMART SSD

UDP I did trim (fstrim -a) and after that the archive was unpacked. However, a little later I received an I / O Error in Thunar, the system did not hang, but stopped functioning normally, I had to reboot. I couldn't even see the dmsg

Answer 1

in /etc/fstab set the discard parameter to the right partitions ? or as an alternative to fstrim in cron?
