Professional reviewers consistently commend the Extreme Portable SSD for its rugged IP55 build and high sequential speeds, noting that it enables smooth 4K video playback and rapid off-loading in demanding environments, while also appreciating the inclusion of necessary cables for immediate deployment.
Consumers echo the professional praise, emphasizing the drive's speed, compactness, and durability for travel, though a common theme is that real-world performance can be limited by the host device's USB capabilities.
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.
