Система зависает при работе с SSD, в чем может быть причина?

Добрый день. Недавно приобрёл SSD (Kingston SSD NOW 240GB) и установил на него Debian 8. Всё вродебы работает нормально, однако никак немогу распаковать большой ~8GB tar архив. В какой-то момент система просто намертво зависает и всё. Свободного места ~160GB.

Перенёс архив на HDD и там он нормально распаковался. В чем может быть проблема? SSD неисправен, или что-то програмное?

На всякий случай прикладываю SMART SSD

UDP Я сделал trim (fstrim -a) и после этого архив распаковался. Однако чу ть позже я получил I/O Error в Thunar, система не зависла, но перестала нормально функционаировать, перешлось перезагрузить. Я даже не смог посмотреть dmsg
