Samsung P9 vs. P7: What to Know Before Buying Samsung’s New USB4 Portable SSDs

Samsung introduced the USB4-based Portable SSD P9 and P7 at Gamescom 2026 as its new portable-storage lineup for creators, gamers and large-file workflows. The P9 is the flagship: its claimed 4,000 MB/s read speed, 3,800 MB/s write speed and 8TB option are aimed at demanding media and data work. Those are manufacturer ratings, however, not a guarantee of the same results on every computer, camera or cable. 89

P9 and P7 at a glance

	Portable SSD P9	Portable SSD P7
Connection	USB4	USB4
Headline performance	Up to 4,000 MB/s sequential read; up to 3,800 MB/s sequential write	Samsung’s more affordable USB4 model; check the regional product listing for the applicable capacity and speed tier
Capacity range announced for the P Series	1TB, 2TB, 4TB and 8TB, with market availability varying	1TB, 2TB, 4TB and 8TB, with market availability varying 810
Best fit	High-resolution media workflows, large project transfers, games and data-heavy work	General creator storage, games, backups and large-file transfers

Samsung describes the P9 as the world’s first 8TB USB4 portable SSD capable of up to 4,000 MB/s. That is Samsung’s category claim, so it should be read as a vendor specification rather than an independently verified industry benchmark. 8

The practical upgrade over the T9

The P9’s headline speeds are roughly double the stated maximum of Samsung’s previous T9: the 4TB T9 is rated for up to 2,000 MB/s read and write over USB 3.2 Gen 2×2. The newer P9 uses USB4, which gives it a higher-bandwidth connection for sequential transfers. 68

For a working photographer, editor or game-library hoarder, that difference matters most when moving very large files—not when opening everyday documents or browsing a drive. Samsung positions the P9 for demanding workflows including high-resolution video, large-scale game installs and AI-related creative workloads. 822

Samsung also says the P9’s sustained-write capability supports direct 12K recording. That does not mean every camera can record 12K footage to it: the camera must support external SSD recording, and the usable result depends on its codec, recording format, cable, power behavior and sustained-write requirement. 2117

Pricing and availability

Samsung said the P Series would begin a global rollout in September 2026, with capacity availability varying by market. 89

Reported US launch pricing is:

• P9: $339.99 for 1TB, $649.99 for 2TB, $1,349.99 for 4TB and $2,699.99 for 8TB.
• P7: $289.99 for 1TB, $549.99 for 2TB, $1,149.99 for 4TB and $2,299.99 for 8TB. 10

Regional MSRPs, launch dates and configurations can differ, so buyers should confirm the local Samsung store or authorized retailer listing before ordering.

USB4 is the key buying requirement

A USB-C-shaped port is not automatically a USB4 port. To approach the P9’s stated 4,000 MB/s ceiling, the host system needs a 40Gbps USB4 connection and a cable capable of that link speed. A drive connected to an older 10Gbps or 20Gbps USB port will negotiate down to the speed supported by that system. 3

Before buying, check:

1. Your computer’s port specification. Look for USB4 40Gbps support, not merely USB-C.
2. The cable specification. A USB-C cable may provide charging or basic data transfer without supporting a 40Gbps connection.
3. Your camera or device’s external-drive support. USB4 on the SSD does not add recording capability to a camera that lacks it.
4. Real-world test results. Peak sequential benchmarks do not fully describe sustained writes, thermal behavior or performance with a particular host.

The last point is especially important. A lab-tested USB4 competitor, LaCie’s Rugged SSD4, measured about 3,183 MB/s read and 3,185 MB/s write in StorageReview’s testing, despite its 40Gbps USB4 interface. That is not a P9 comparison, but it illustrates why host behavior, thermals and workload can matter as much as an advertised peak number. 11

Security and durability: what is confirmed—and what to verify

Samsung’s announcement presents the new P Series as combining high capacity and broad compatibility with durability, but the available launch material does not establish a single universal IP rating, drop-test height or warranty term for every P9 and P7 configuration. 68

That makes the buying advice straightforward: verify the data sheet for the exact regional model before treating either drive as rugged or weather-resistant. In particular, confirm the included cable, drop rating, ingress-protection rating, encryption options and warranty terms.

For sensitive footage or client files, a portable SSD should also be part of a backup plan—not the only copy. Drive-level password protection can help if a device is lost, but it cannot replace a separate, tested encrypted backup.

Why the generative-AI launch campaign upset filmmakers

The criticism is primarily about fit and symbolism. Samsung positioned the P9 around professional production and direct 12K recording, while the launch video carried a persistent notice that it had been created with generative AI. CineD characterized the contrast bluntly: a drive intended to store filmmakers’ footage was being marketed with material that was not conventionally filmed. 33

Disclosure addresses whether viewers are told about the technique; it does not resolve objections about creative labor or authenticity. For critics, the campaign suggests a company selling tools to directors, cinematographers, performers, editors and post-production teams chose not to foreground those people in the marketing itself.

Some commentary has alleged hallucinated text and the absence of a conventional production crew. Those specifics cannot be treated as established from the available evidence. The documented point is narrower: the campaign disclosed generative-AI use, and the choice drew criticism because of the product’s filmmaker-focused positioning. 33

The response also landed in the context of Samsung’s earlier Galaxy S26 social ads. Reporting on those ads noted that Samsung used or enhanced video with generative-AI tools and included a disclosure, while critics highlighted visible AI-like artifacts and questioned using synthetic footage to promote imaging features. 41

Bottom line

Choose the P9 if you have a genuine 40Gbps USB4 workflow and regularly move high-resolution media, large project folders or game libraries—especially if its 8TB option solves a capacity problem. Choose the P7 if price matters more than the flagship’s throughput.

In either case, do not buy solely on the peak rating. Confirm your port and cable, check the exact regional durability and security specifications, and wait for independent sustained-performance testing if direct recording or professional production is central to your purchase.
