Hi. I was happy to get my first MacBook.

At that time I was curious about my disk speed, so downloaded Blackmagic Disk Speed Test from App Store. After I clicked it, I forgot to cancel (I didn't know it kept running until I felt something strange to this app ) and it lasted for some minutes. I was worried if it occupied my SSD TBWs so installed DriveDX. Consequently I saw the Data Units Written is 1.5TB... This is insane and I am afraid I did something wrong to my Mac...I even did not know how much in 1.5TB the testing app wrote.

Although everything looks fine in DriveDX data, does this testing app ruin my SSD drive?
