The Samsung 9100 Pro is a big, powerful, flagship SSD from one of the biggest names in the game. It brings high-end performance, pushing the limits of its PCIexpress 5.0 interface– on paper, this should be one of the best SSDs ever made, accelerating file transfers and game load times like never before.
But Samsung wasn’t first to market with a top-tier PCIe 5.0 SSD, and there is stiff competition for the kind of cutting-edge performance that Samsung has historically been known for. Still, it is very fast on paper, with a strong endurance rating, five-year warranty, and the option of an attractive, low-profile heatsink for a few dollars extra.
Design and Software
This is a standard M.2 2280 drive, so the dimensions and form-factor will be very familiar for anyone with an NVMe SSD. Samsung sent me the heatsink version of the 9100 Pro and it’s clearly built to a high-standard, with a sturdy, compact design and well machined heatsink fins that give it a quality look and feel. It’s available without the heatsink too, though, should your motherboard have big heatsinks for add-in drives, or you want to use a third-party alternative.
It’s available in sizes from 1TB through 4TB at the time of writing (I’m testing the 2TB version), with plans to release an 8TB model down the line.
Forget CrystalDiskInfo, if you have a Samsung SSD you get to use the excellent Samsung Magician Software which combines detailed drive monitoring with easy data migration, secure erase, drive encryption, and performance benchmarks, among other useful settings and tests.
It’s not something everyone will feel the need to play around with, but if you want to keep a close eye on your new flagship SSD, Samsung’s Magician tracks drive health, system information, and has useful built-in tools like secure erase and drive encryption.
Specs
The specifications for the Samsung 9100 Pro are about as good as you can get with a modern, high-end PCIe 5 SSD. Although that’s never the full picture for any component, Samsung sets off on the right foot with this drive.

The 9100 Pro uses Samsung’s 236-layer TLC NAND Flash, which is the company’s most effective memory to date. This NAND is also used in the older 990 Evo Plus and 990 Pro models, but with a newer controller and interface, this drive is much faster.
The sustained read and write speeds of 14,700 MBps and 13,400 MBps, respectively, are competitive with other top PCIe 5 drives like Sandisk’s WD Black SN8100 and Crucial’s T710. While you’re unlikely to encounter these speeds outside of benchmarks and large file transfers, if you want to move a lot of data around between drives (ideally between two PCIe 5 drives) then the 9100 Pro should do it exceptionally quickly.
The random read and write performance is arguably more impressive, though, and highlights how far we’ve come in “smaller” capacity drives like this, showing how capable Samsung’s top flash designs are.
The endurance rating of 1200 TBW for this 2TB model (up to 4800 TBW for the 8TB model) is plenty for the average user, though there are more durable professional drives out there if you expect to hammer yours on a daily basis for professional workloads.
The Samsung 9100 Pro joins the high-end PCIe 5 market at a time of increasing competition. There are standouts like the Crucial T705 with its huge heatsink and impressive numbers leading the pack, but its high price of $260 reflects that. The WD SN8100 offers similar specs at a similar price, giving the 9100 Pro at $260 some real head to head action with little separating them. Ditch the heatsinks and their prices match up even closer.
Then there’s the slightly slower, but still fast Corsair MP700 Pro and Elite, which are still blazingly fast in real-world workloads, but significantly cheaper.
Considering the limited utility for the cutting-edge performance of a top PCIe 5 SSD in 2025, too, it’s also worth considering high-end PCIe 4 drives. Those include Samsung’s own 990 Pro, which is available at the same capacity for just $150.
Performance
To test the 9100 Pro I fitted it to my test system with an AMD Ryzen 9 7950X3D, an Asus ROG Crosshair X670E Hero, 32GB of RAM at 5,200MHz and a Radeon RX 7900 XTX. I installed the drive in the top-most PCIe 5 NVMe slot and tested on a brand new installation of Windows 11 running the latest 24H2 version, with the latest drivers and BIOS updates applied.
In CrystalDiskMark, the 9100 Pro actually surpassed its rated sustained read and write performance showing how utterly fast this drive can be when shifting raw data around.
That was backed up by my 10GB file transfer test. Moving it from a PCIe 4 WD SN850X 2TB model to the 9100 Pro (Write) took just 3.9 seconds, and moving it back again (Read) was even faster, at 3.4 seconds. If you frequently move large files or folders between drives and want one that will do it exceptionally quickly, the 9100 Pro is among the fastest there is.
In real-world gaming benchmarks I saw equally impressive results. When running the Final Fantasy XIV: Dawntrail benchmark, we clocked a total loading time of just 6.2 seconds. All scenes loaded in under two seconds, and the first and fifth were well under a second a piece. That’s not much faster than a high-end PCIe 4 SSD, but it’s still plenty fast.
The only place where I found any kind of anomalous performance was in 3D Mark Storage. There I recorded a respectable, if unimpressive, 3,269 points, with an average access time around 55 micro-seconds.
Although I’m not the only one to have recorded a sub-4000 score with this particular drive on this particular benchmark, many contemporaries have managed 5-6,000+ scores. Iran it multiple times and it came back the same every time. I initially thought it might be the SLC running out, but I had similar performance throughout all the individual test runs during the benchmark.
I’ve reached out to Samsung for comment and will update this review if and when I hear back.
One area where this drive did really impress me, though, was temperature. Although the drive itself gets blisteringly hot to the point that touching it became a legitimate burn hazard, the controller inside was chilly the entire time. Even after sustained load during the 3D Mark test run, it didn’t even break 40 degrees.
That said, this drive is clearly putting out a lot of heat so I’d recommend the heatsink or some kind of strong active cooling.
