What is Reddit's opinion of UltraDefrag?

From 3.5 billion Reddit comments

that is a low performance drive and i'm guessing you haven't reinstalled windows 7 for a while?

try downloading ultradefrag: https://ultradefrag.net/en/index.shtml your files might be all over the place on the drive causing the slow read/write times.

after that try running this and post the results: https://hdd.userbenchmark.com/Software

Download and install ultradefrag, it's a visual representation of the disk defragmentation process, I miss the old defrag from windows 3.X and 98, this comes close to it.

Just sit there and watch the data get moved around (unless you have an SSD then it's useless).
