Samsung P9 portable SSD is a US$339.99 bet that your work involves moving enough data to notice a 4,000 MB/s ceiling. Samsung says the new USB4 drive can read at up to 4,000 MB/s and write at up to 3,800 MB/s. Those are very impressive claims. They are not independent test results, and most people backing up documents will never make the extra speed earn its keep.
My verdict is to wait. The P9 makes sense for repeated large video transfers, direct recording, and other sustained jobs on a computer with a 40 Gbps USB4 port. Everyone else should compare the actual Canadian price with a proven Samsung T9 once P9 stock and reviews arrive. Paying launch money to move a folder before making coffee is not a productivity system.
This is specification analysis, not a hands-on review. I have not tested the P9. Every performance number below is a Samsung claim unless I identify an independent measurement.
Bottom line: The Samsung P9 Portable SSD is the clearest option to consider if the trade-offs below fit your setup.

Samsung P9 Portable SSD Verdict
The Samsung P9 portable SSD has a clear customer: someone who moves hundreds of gigabytes regularly and already owns the right host hardware. Samsung positions it for professional production, including direct 12K recording and large RAW files. That claim needs compatible cameras, cables, formats, and sustained performance that has not yet been independently measured. Samsung P9 Portable SSD on Amazon
The broad capacity range is useful. Samsung announced 1TB, 2TB, 4TB, and 8TB models, making this the first 8TB USB4 portable SSD rated for up to 4,000 MB/s. The catch is equally broad pricing. The 8TB model costs US$2,699.99, so its most portable feature may be the speed at which it empties a hardware budget.
Confirmed Specs and Prices
Samsung’s August 26 announcement lists P9 MSRPs of US$339.99 for 1TB, US$649.99 for 2TB, US$1,349.99 for 4TB, and US$2,699.99 for 8TB. The global rollout begins in September, with capacities varying by market. Samsung has not announced Canadian prices.
The live Samsung P9 product page confirms USB4 and the 4,000/3,800 MB/s read and write claims, but it showed the 1TB model as out of stock when checked September 2, 2026. Samsung’s regional specification page lists a five-year limited warranty, AES 256-bit hardware encryption, backward compatibility with older USB devices, and a USB-C cable in the box. None of that proves sustained speed once the cache fills.
P9 vs T9
The T9 is the useful reference because it is established, available in Canada, and half as fast on Samsung’s headline read number. The price cells below use different currencies and should not be compared as converted equivalents. A Canadian P9 price does not exist yet.
| Drive | Observed or announced price | Interface | Claimed read/write | Capacities | Main drawback |
|---|---|---|---|---|---|
| Samsung P9 | US$339.99 MSRP, 1TB | USB4, 40 Gbps | Up to 4,000/3,800 MB/s | 1TB, 2TB, 4TB, 8TB | No independent performance tests or Canadian price |
| Samsung T9 | CA$314.99, 1TB | USB 3.2 Gen 2×2, 20 Gbps | Up to 2,000/1,950 MB/s | 1TB, 2TB, 4TB | Many computers cannot supply a 20 Gbps Gen 2×2 link |
The chart shows the marketing ceiling, not the experience of copying a mixed project folder. TechSpot’s independent launch coverage confirms the announced numbers and makes the same price objection, but it does not contain a hands-on benchmark of the P9. Until a reviewer measures long writes, thermals, and cache behaviour, the honest performance table has blank spaces.
The USB4 Port Is the Buying Test
USB-C describes the connector, not its speed. A laptop can have the right oval socket and still limit an external drive to 5, 10, or 20 Gbps. The Samsung P9 portable SSD needs a 40 Gbps USB4 connection, the included high-speed cable, and a workload that reads or writes sequentially to approach Samsung’s numbers.
Check the exact laptop or motherboard specification before buying. If it says only “USB-C” or “USB 3.2,” keep reading until a transfer rate appears. Thunderbolt and USB4 compatibility can also vary by generation and implementation. The logo beside a port is more useful than the colour of the plastic inside it, but the system manual wins every argument.
Where the Extra Speed Matters
Large sequential transfers are the best case. Video editors moving camera originals, creators working from an external project drive, and anyone rotating very large local backups can turn higher throughput into saved time. The P9 may also be useful as fast portable storage for local AI model files, but it will not make inference faster after a model is loaded into system memory or VRAM.
Ordinary office work is a bad sales demo. Word documents, browser profiles, invoices, and thousands of small files introduce overhead that a maximum sequential number ignores. A faster drive can still help, but the difference will not resemble a bar that became exactly twice as long. For backup planning, the site’s self-hosted cloud storage guide is more important than shaving seconds from one local copy.
What I Would Buy
I would not preorder the Samsung P9 portable SSD. I would wait for sustained-write tests and Canadian pricing, then compare cost per terabyte with the site’s live Canadian SSD price tracker. The current storage market is too expensive for faith-based throughput.
If the drive is needed now, the 1TB Samsung T9 was listed at CA$314.99 by Canada Computers on September 2, with online stock sold out and limited store pickup shown. That is not cheap. It is at least a product with an established record and a Canadian price. Read the site’s SSD buy-or-wait analysis before treating any current listing as normal.
Who Should Skip This
Skip the P9 if your computer lacks a documented 40 Gbps USB4 port, your main job is document backup, or the drive will spend its life attached to a game console. Skip it if losing the drive would be catastrophic, too. Hardware encryption is useful, but one portable SSD is not a backup strategy.
Buy only after independent reviewers test sustained writes, temperature, power use, sleep behaviour, and performance across Windows and macOS. A peak benchmark can finish before the difficult part begins. That is particularly relevant at 4TB and 8TB, where a long transfer can outlast a fast cache and expose thermal limits.
What Is Still Unknown
Samsung has confirmed the US MSRPs, capacity range, USB4 interface, maximum sequential speeds, September rollout, encryption, and warranty. It has not confirmed Canadian pricing or which capacities Canada will receive first. Independent reviewers have not published exact-model hands-on performance on the Canadian page-one results checked for this article.
Sustained write speed, cache size, controller behaviour, real temperature, idle power, and cross-platform consistency remain unanswered. Those details decide whether the P9 is a professional tool or a very fast screenshot of a benchmark. Wait for them.
Our pick: The Samsung P9 Portable SSD is the best choice here because its strengths line up best with the use case covered here.

Frequently Asked Questions
How fast is the Samsung P9 portable SSD?
Samsung claims up to 4,000 MB/s sequential reads and 3,800 MB/s sequential writes over USB4. These are manufacturer figures. Exact-model independent benchmarks were not available when checked September 2, 2026.
How much does the Samsung P9 cost?
US MSRPs are US$339.99 for 1TB, US$649.99 for 2TB, US$1,349.99 for 4TB, and US$2,699.99 for 8TB. Samsung had not announced Canadian prices at publication.
Will the P9 work on an ordinary USB-C port?
Samsung lists backward compatibility with older USB standards, so it should connect to many USB-C systems. The port will limit speed. You need a documented 40 Gbps USB4 connection to pursue the advertised maximum.
Is the P9 better than the Samsung T9?
The P9 has twice the T9’s claimed maximum read speed and adds an 8TB option. The T9 is the safer immediate purchase because it has established availability and review history. The P9 needs independent sustained-performance testing before “better” means more than a larger number.
The Short Version
The Samsung P9 portable SSD is a serious USB4 launch with unserious prices for ordinary backup work. Its 4,000 MB/s read claim and 8TB ceiling suit demanding production workflows, but only with the right port and only if sustained tests support the headline. Wait for Canadian pricing and independent benchmarks. Buy a proven T9 only when the work cannot wait with you.
