The Samsung SSD P9 is the company's latest external solid-state drive, boasting USB 4 Gen 3x2 connectivity and promised speeds of up to 4,000 MB/s read and 3,800 MB/s write. In our testing, it delivers near those figures, making it one of the fastest external SSDs available. However, it arrives at a time when memory prices are soaring, which complicates the buying decision.
What is the Samsung SSD P9?
The P9 is Samsung's new flagship external SSD, aimed at professionals and enthusiasts who need to move large files quickly. It uses the USB 4 Gen 3x2 interface, which offers a bandwidth of 40 Gbps. This is double the speed of USB 3.2 Gen 2x2 and four times that of standard USB 3.2 Gen 2. The drive is available in 2TB and other capacities, and it's designed to be portable and durable.
In a market where external SSDs are becoming commodities, the P9 stands out by pushing the interface to the limit. But that speed comes with caveats: you need a compatible host device to take full advantage, and the price is higher than ever due to current memory market conditions.

Performance: How fast is it really?
We tested the 2TB model using a compatible USB 4 host. In sequential read tests, the drive reached close to 3,900 MB/s, while writes peaked around 3,700 MB/s. These are impressive numbers, though slightly below Samsung's claims. In real-world file transfers, the P9 handled a 20GB folder of mixed media in under 10 seconds, which is a massive time saver for video editors and photographers.

However, if your computer lacks USB 4, the drive will fall back to slower speeds. On a USB 3.2 Gen 2 port, we saw around 1,000 MB/s, which is still fast but not groundbreaking. So the P9's potential is only realized with the right hardware.

Key takeaways
- USB 4 Gen 3x2 interface delivers up to 40 Gbps bandwidth.
- Real-world speeds approach 4,000 MB/s read and 3,800 MB/s write with compatible hardware.
- Backward compatible with USB 3.x, but speeds are limited by the host.
- Available in 2TB and other capacities; pricing is high due to memory market trends.
- Ideal for creative professionals who frequently transfer large files.
Price and market context
The SSD P9 launches at a time when NAND flash and DRAM prices are climbing. This makes any storage purchase a tough sell, especially for a premium product like the P9. The 2TB model we tested commands a premium over previous-generation drives. While the performance is top-tier, the value proposition is weakened by the current market.

For those who can wait, prices may eventually stabilize, but if you need speed now, the P9 is one of the best options available. Just be prepared to pay for it.
Comparison with other external SSDs
Here's how the Samsung SSD P9 stacks up against some common alternatives.
| Drive | Interface | Max Read (MB/s) | Max Write (MB/s) | Typical Price (2TB) |
|---|---|---|---|---|
| Samsung SSD P9 | USB 4 Gen 3x2 | 4,000 | 3,800 | High |
| Samsung T7 Shield | USB 3.2 Gen 2 | 1,050 | 1,000 | Moderate |
| SanDisk Extreme Pro | USB 3.2 Gen 2x2 | 2,000 | 2,000 | Moderate-High |
| Crucial X10 Pro | USB 3.2 Gen 2x2 | 2,100 | 2,000 | Moderate |
As the table shows, the P9 is in a class of its own for speed, but you'll pay a premium for that performance.

Who should buy it?
The Samsung SSD P9 is best suited for video editors, photographers, and other professionals who regularly work with large files and have a USB 4-equipped computer. If you're a casual user, a cheaper USB 3.2 drive will likely suffice. Also, consider whether you need the absolute fastest speeds or if a slightly slower drive would save you money.
