Performance Degradation

As you can see with the following results from our benchmarks even Intel still faces problems regarding performance degradation when the drive is/was filled with data. Performance drops regarding reading processes could be possibly tolerated if we close both eyes but the writing performance lets nearly no other option the low level formatting the drive after it was filled to the top with data.
