Samsung 9100 Pro

The 9100 PRO is stupid fast, stupid expensive, and completely overkill for most people. If you need the best Gen5 drive on the planet, this is it.

The numbers here are genuinely absurd. 2,200K random read IOPS and 2,600K random write IOPS put this drive at the 100th percentile for random performance, which means nothing else we've tested even comes close. The 5nm controller is a big part of the story too, Samsung claims up to 49% better power efficiency than the 990 PRO, and that matters when you're pushing PCIe 5.0 speeds that can turn lesser drives into space heaters. The heatsink version we tested stayed cool under sustained load, which is not something we say often about Gen5 drives.

The Crucial T705 is the closest competitor in raw speed, but it runs hotter and doesn't match the 9100 PRO's random IOPS. The WD_BLACK SN850X is a fantastic Gen4 drive that costs way less, but it's not even in the same performance league. The Kingston KC3000 and Seagate FireCuda 530R are solid Gen4 options too, but they're fighting last generation's battle. If you want Gen5 and you want it now, Samsung is the clear winner. If you can wait or don't need bleeding-edge speed, grab an SN850X and save a pile of cash.

This drive is expensive, no way around it. US listings run $1,279 to $1,400, and Canadian buyers are looking at $1,570 CAD. But here's the thing: if you actually need this level of performance, there's nothing else that delivers it. For AI workstations, 8K video editing rigs, or anyone who moves terabytes of data daily, the price is justified. For everyone else, it's like buying a Formula 1 car to commute to the grocery store.

The Samsung 9100 PRO is the fastest consumer SSD we've ever tested, full stop. Sequential reads hit 14,800 MB/s and writes land at 13,400 MB/s, which is roughly double what the already excellent 990 PRO could manage. If you're moving massive video files, running AI workloads, or just want the absolute best Gen5 drive on the market, this is it. The 4TB capacity with heatsink means you're not sacrificing space for speed either.

If you're just gaming or doing everyday productivity work, this drive is massive overkill. You'll get 95% of the real-world experience from a good Gen4 drive like the WD_BLACK SN850X for less than half the price. Save your money and put it toward a better GPU or more RAM instead.

The Samsung 9100 PRO is the undisputed king of consumer SSDs right now. It's not for everyone, the price alone guarantees that. But for the people who need it, AI researchers, professional video editors, data hoarders with deep pockets, there is simply nothing better. Buy it if you need the absolute best and money isn't the deciding factor.
