KitGuru and other professional reviewers conclude that the Extreme PRO Portable SSD lives up to its premium positioning, delivering top-tier transfer speeds, a rugged yet compact design, and strong security features, making it a go-to choice for content creators and mobile professionals who need reliable, high-speed storage.
The source data does not contain direct consumer reviews, so everyday user sentiment cannot be directly assessed; the product is marketed toward professionals and creators, suggesting positive expectations for speed and durability.
Professional reviewers commend the X9 for its ultra-small footprint, strong read performance and drop-proof design, noting it as a convenient, high-speed solution for mobile professionals. However, they point out that its sustained write speeds lag slightly behind rivals and that the lack of an IP rating makes it less rugged than competing models like the Samsung T7 Shield.
Everyday users highlight the drive's fast read speeds, pocket-size convenience, and seamless plug-and-play experience across a wide range of devices. The main concerns expressed are the scarcity of user reviews, the absence of an official IP rating, and minor confusion over the exact weight listed in different sources.
