Hi Merovingio,
The traffic reported on SMART total GB wirtten is different from user written data, because of a SSD term called write amplification, the SSD may doing background write for optimization, recycling, trim and other reason. Especially when you have the drive almost full, the drive’s firmware may try to optimize for performance and cause more than usual traffic.
From the 0 reassigned block count, 0 grown bad block count and 0 error/fail I think the drive is in a healthy state, however if you see sudden dramatic increase of any of these attribute I would suggest you contact our support center and consider a replacement.
