Hello, this is not an issue especially if you copy a big piece of information, I suggest you to install the latest version of the SSD toolbox version 2.0 and run the Intel SSD Optimizer and the System configuration tuner to keep the SSD in good shape.
This is normal, the Intel G2 series can only endure 35TB writes in total, after it dies.
Because you have written 580GB, the drop to 99% is normal.
Mauriceb, please correct me if I'm wrong.
