I have the Transcend SSD 720 256GB 2,5" 7mm disk. And randomly I get disk IO errors in utorrent and large files copying to external will fail. I have removed it from my laptop since I need max stability. I use my laptop on exams. How can I really benchmark it/make-it-sweat whilst connected to my desktop? I want to re-create some of the fails as I need proof if I am to return it. Firmware is updated. BIOS on laptop is updated. I could just completely nul the disk and then check for bad sectors, but is there anything else I could use for testing?
Edit: It has 7 bad sector replacement operations. What does it mean?
