September rollout; independent tests are still needed
Samsung has announced US MSRPs and a global September rollout, but capacities and exact dates vary by market. Maximum performance requires compatible USB4 hardware, and sustained transfer, temperature and P7 speed results should be confirmed by independent testing.
Fact-checked: August 31, 2026
Samsung is adding two USB4 portable SSD families in September. The flagship P9 is rated for sequential reads up to 4,000MB/s and writes up to 3,800MB/s. The more affordable P7 emphasizes compatibility across computers, phones, cameras and consoles plus tested resistance to two-meter drops.
Both lines are planned in 1TB, 2TB, 4TB and 8TB capacities. US P9 prices begin at $339.99, while P7 starts at $289.99. The gap is roughly 17% to 18% at each capacity, so the key question is whether the P9 performance tier improves a workflow enough to justify the premium.
Samsung describes the 8TB P9 as the first 8TB USB4 portable SSD supporting speeds up to 4,000MB/s and says it can support demanding direct-recording workflows. Those are manufacturer claims. Buyers should wait for tests of sustained writes, thermals, device compatibility and the P7’s actual transfer ceiling before treating launch figures as everyday results.

P9 or P7: The Short Answer
Choose P9 for a verified USB4 workstation and workloads that move very large video, photo, AI or game libraries every day. Choose P7 for portable backup and multi-device use when price matters more than the P9’s advertised peak. Wait for reviews if sustained performance is essential.
- P9 peak claim: up to 4,000MB/s read and 3,800MB/s write.
- P9 capacities: 1TB, 2TB, 4TB and 8TB from $339.99.
- P7 positioning: lower-cost USB4 storage with broad host compatibility.
- Availability: global rollout starts in September; timing and capacities vary.
Samsung P9 and P7 US Prices
| Capacity | P9 MSRP | P7 MSRP | P9 premium |
|---|---|---|---|
| 1TB | $339.99 | $289.99 | $50 / 17.2% |
| 2TB | $649.99 | $549.99 | $100 / 18.2% |
| 4TB | $1,349.99 | $1,149.99 | $200 / 17.4% |
| 8TB | $2,699.99 | $2,289.99 | $410 / 17.9% |
What the P9 Adds
P9 is designed for high-bandwidth production. Samsung says its sequential speeds are roughly twice those of the USB 3.2 Gen 2×2 T9 and highlights 12K direct recording as a supported use case. In practice, the camera, recording format, cable, host controller, file system and thermal conditions all influence whether a workflow approaches the advertised number.
The 8TB option is unusual for a pocket drive, but it costs $2,699.99. At that level, buyers should compare service terms, backup strategy and whether multiple smaller drives reduce the impact of a single device failure.
Check P9 and P7 Availability
Match the exact capacity and seller; launch inventory may differ by region.
Why the P7 Could Be the Better Value
P7 is $50 to $410 less than P9 depending on capacity. Samsung lists compatibility with desktops, laptops, smartphones, gaming consoles and cameras and says it completed two-meter drop, shock and vibration testing. That combination is attractive for backups and transporting project files.
P7 peak speeds were not stated in the launch release
Do not assume that “USB4” means the P7 matches P9. Samsung’s announcement provides explicit P9 figures but does not publish equivalent P7 sequential read and write numbers.
Will Your Computer Reach USB4 Speeds?
- Confirm that the specific port supports USB4 data, not merely the USB-C connector shape.
- Use the supplied or certified high-bandwidth cable; a charging cable can be much slower.
- Check whether the host shares bandwidth with displays, docks or other devices.
- Expect large sustained transfers to differ from short sequential benchmark bursts.
- Keep a second backup: fast portable storage is not a complete backup system by itself.
A creator choosing a new computer should compare the full port specification, not the processor label alone. The Acer Swift Neo AI India guide and M6 Mac mini configuration guide show how storage and connectivity influence a purchase.
Which Capacity Makes Sense?
| Capacity | Best fit | Caution |
|---|---|---|
| 1TB | Portable working set and light backup | Fills quickly with high-resolution video |
| 2TB | Balanced creator and gaming library | Still needs a separate archive copy |
| 4TB | Large active projects | High launch price; compare desktop SSD options |
| 8TB | Consolidated professional field storage | Very high replacement cost and single-device risk |
FrediTech Verdict
P9 is the clear specification leader for properly equipped professional systems. P7 is likely the rational choice for many backups and cross-device transfers, but Samsung has not yet given the launch release a P7 speed table. Do not preorder on the interface name alone; confirm host support and wait for independent sustained-write testing if performance is mission-critical.
Frequently Asked Questions
How fast is the Samsung P9?
Samsung rates P9 for sequential reads up to 4,000MB/s and writes up to 3,800MB/s. Real transfers depend on host, cable, workload and temperature.
How much does Samsung P7 cost?
US MSRPs are $289.99 for 1TB, $549.99 for 2TB, $1,149.99 for 4TB and $2,289.99 for 8TB.
Does USB-C mean my laptop supports full USB4 speed?
No. USB-C describes the connector. Check the laptop’s port specification for USB4 bandwidth and use a suitable cable.
When do P9 and P7 go on sale?
Samsung says the global rollout begins in September 2026, with exact dates and available capacities varying by market.
