72 out of 100 low confidence 7 reviews
The Samsung 9100 Pro is generally praised for its blazing-fast speeds, especially in data transfers and large file loads, with several users noting it's noticeably faster than the 990 Pro. However, one verified buyer experienced a complete drive failure within two weeks, which is a significant concern. Most reviewers recommend it for high-end builds, but advise getting the heatsink version or a good aftermarket cooler.
