Samsung P9 SSD review: Speedy USB4 in a slim package
The demand for high-speed flash memory and RAM has never been higher, largely fueled by the insatiable appetite of AI hyperscalers. Yet, for content creators, videographers, and media collectors, the bottleneck isn’t just raw capacity—it’s speed, size, and portability. Enter Samsung’s latest offering: the Portable SSD P9, a drive designed to deliver professional-grade performance in a form factor that truly feels next-generation.
The P9 steps into the external storage arena by leveraging the cutting-edge USB4 protocol, promising blistering data transfer rates. It is available in various capacities, ranging from 1TB up to a massive 8TB, though it is currently stocked in the 2TB variant. With sequential read speeds up to 4,000 MB/s and write speeds nearing 3,800 MB/s, the P9 positions itself firmly at the top tier of portable storage solutions.
Beyond raw throughput, Samsung prioritized design and user experience. The P9 adopts a surprisingly slim, boxy shell measuring only 3.5 x 2.6 x 0.3 inches, making it significantly less cumbersome than previous models. Crucially, it swaps out older, textured coatings for a solid metal shell that gives it a premium, robust feel. Completing the package is an impressively long, 16-inch, braided cable that feels custom-made, complete with features that make desktop use feel truly pocket-friendly.
The drive isn’t just about aesthetics; it’s about intelligent management. Samsung’s companion software, Samsung Magician, provides a feature-rich toolbox for monitoring drive health, tracking performance, managing temperatures, and even enabling 256-bit hardware encryption. This suite of tools ensures that professional users have complete control over their high-performance storage.
When placed against the competition—including rivals like Sandisk’s Extreme Pro, LaCie’s Rugged SSD4, and Corsair’s popular EX400U—the P9 proves its mettle. While some competitors offer impressive price points, the P9 consistently demonstrated superior performance in synthetic benchmarking and, notably, excelled in sustained write performance. This difference is critical for heavy media workloads, where the ability of a drive to maintain speed under pressure truly matters.
Despite its performance edge, the P9 commands a premium price, starting at $339 for the 1TB model and reaching nearly $2,900 for the 8TB capacity. While the cost is certainly steep compared to some alternatives, the testing suggests that for serious professional users who demand the absolute fastest, most durable, and most elegantly designed external drive available, the P9 justifies its place at the top of the market. It delivers a blend of top-tier speed and sleek design, setting a new benchmark for portable storage.
