Samsung 9100 PRO

The Samsung 9100 PRO 8TB is the fastest SSD in our database with 14,800 MB/s reads and best-in-class random performance at 2,200K/2,600K IOPS. It's a workstation monster with 4,800 TBW endurance and a 96.2/100 workstation score. Just be ready to pay around $2,570 to $2,599 USD for the privilege.

Let's talk numbers, because this drive is all about them. Sequential reads hit 14,800 MB/s, which is the kind of speed that makes a 100GB game install feel like copying a folder of memes. Writes aren't far behind at 13,400 MB/s. For context, that's roughly double what most PCIe 4.0 drives manage, and it lands this drive in the 99th percentile for speed in our database. Only a handful of drives even come close.

Random performance is where things get silly. 2,200K random read IOPS and 2,600K random write IOPS are the best numbers we've ever recorded, a 100th percentile ranking. That means AI workloads, massive databases, and heavily modded games that hammer storage with tiny file operations will absolutely fly. Samsung's in-house controller and DRAM cache keep things consistent under load too. The 4,800 TBW endurance rating is well above average, so you can hammer this thing daily for years without worrying about wearing it out.

Against the Western Digital WD_BLACK SN850X, the Samsung wins on raw speed, 14,800 MB/s reads versus the SN850X's PCIe 4.0 ceiling, but the WD drive costs a fraction of the price and has way more social proof behind it. The Crucial T705 is the closest PCIe 5.0 competitor, and while it's fast, it doesn't match the 9100 PRO's random IOPS or 8TB capacity. The Seagate FireCuda 530R and Kingston FURY Renegade are both solid PCIe 4.0 drives that make more sense for most people, but neither can touch this Samsung's throughput. If you want the fastest drive money can buy, the 9100 PRO is alone at the top. If you want 90% of the real-world performance for half the price, the SN850X or FireCuda 530R are the smarter buys.

At $2,570 to $2,599 USD, this drive costs more than most complete gaming PCs. That's a tough pill to swallow, but you're paying for the absolute best. When you factor in the 8TB capacity, the price per gigabyte is actually not outrageous for flagship PCIe 5.0 storage, especially with this level of endurance and the included heatsink. Canadian buyers are looking at $3,770 CAD, which is a similar story. If you need this much fast storage, the value is there. If you just want a snappy boot drive, you're overspending by a factor of about ten.

The Samsung 9100 PRO 8TB is the fastest drive we've ever tested, full stop. 14,800 MB/s sequential reads and 13,400 MB/s writes put it in the 99th percentile for speed, and its random performance is literally the best in our database at 2,200K read IOPS and 2,600K write IOPS. That's a 100th percentile ranking, which means nothing else we've tested touches it. You're looking at the new king of PCIe 5.0 storage.

But this isn't just a speed demon. It's also an 8TB monster with a 4,800 TBW endurance rating and Samsung's in-house controller paired with TLC NAND and DRAM cache. The heatsink version we're looking at keeps thermals in check, and hardware encryption is baked in. The catch? It's priced like a small used car, and portable use is basically a non-starter at 27.8/100.

If you're on a laptop or need portable storage, skip this. The 27.8/100 portable score is one of the worst we've seen for that use case, and the heatsink makes it a non-starter for most thin machines. Gamers on a budget should also look elsewhere, a $100 PCIe 4.0 drive will load games nearly as fast in real-world terms. And if you're the type who reads reviews before buying, the 32nd percentile social proof ranking means there's not much long-term feedback yet. Early adopters only for now.

The Samsung 9100 PRO 8TB is the best SSD we've ever tested, and it's not particularly close. The 100th percentile random performance and 99th percentile speed rankings tell the story. For workstation users, content creators, and anyone running AI workloads or massive game libraries, this is the drive to beat. The 96.2/100 workstation score backs that up. Just know that you're paying a serious premium for the privilege, and if you're on a laptop or need something portable, look elsewhere.
