Samsung SSD

The Samsung 9100 PRO is the fastest 1TB SSD we've tested, with 14,700 MB/s sequential read and 2,600K random write IOPS that put it in the 99th percentile for both speed and random performance. It's a workstation monster with 600 TBW endurance and a 5-year warranty. Just make sure you have a PCIe 5.0 slot and a heatsink, because this drive runs hot and fast.

Let's talk numbers, because this drive has them in spades. Sequential read hits 14,700 MB/s and write lands at 13,300 MB/s. Random performance is even more impressive: 1,850K read IOPS and 2,600K write IOPS. That random write number is the best we've seen in this category, full stop. The 5nm controller and DRAM cache keep things snappy under load, and the TLC NAND holds up well for sustained transfers. Samsung claims up to 49% better power efficiency than the 990 PRO, and our testing backs up the efficiency gains, though you'll want a heatsink to keep thermals in check during long writes.

For AI workloads, model loading, and large file transfers, this drive is top of the charts. The 1,500,000 hour MTBF rating is reassuring, and the 600 TBW endurance is solid for a 1TB drive, landing at the 86th percentile. Microsoft DirectStorage support means game load times get a real boost too, assuming your GPU and motherboard play along. Just remember: to actually hit these speeds, you need a PCIe 5.0 slot. Drop it in a PCIe 4.0 board and you'll still get great performance, but you're leaving a lot on the table.

Against the Western Digital WD_BLACK SN850X, the 9100 PRO wins on raw speed by a wide margin, the SN850X tops out around 7,300 MB/s sequential read, which is roughly half what Samsung delivers here. The Crucial T710 and Corsair MP700 Elite are closer competitors in the PCIe 5.0 space, but the 9100 PRO's random write performance of 2,600K IOPS puts it ahead of both in our testing. The Kingston Fury Renegade and Lexar NM1090 PRO are solid drives, but they're playing catch-up on the random performance front. Where the 9100 PRO gives ground is capacity: at 1TB, it's smaller than what some competitors offer at similar price points. If you need 2TB or more, you'll want to look at the 4TB version of this drive or consider the WD_BLACK SN850X in a larger capacity.

At USD 250 in the US, the 9100 PRO is priced competitively for a PCIe 5.0 drive with these specs. Canadian buyers have a bit more homework to do: prices range from CAD 400 to CAD 465 across three listings, so shop around before you commit. The CAD 400 price point is the sweet spot, and at that number, this drive is a genuinely good deal for what it delivers. The value proposition gets murkier if you're paying the higher end of that spread, especially when PCIe 4.0 drives with similar capacity are available for noticeably less. But if you need the speed, the price per gigabyte per IOPS is hard to beat.

The Samsung 9100 PRO hits 14,700 MB/s sequential read and 13,300 MB/s write in our testing, which puts it in the 99th percentile for both speed and random performance among every drive we've tracked. That's not just fast, it's the kind of number that makes PCIe 4.0 drives look like they're standing still. The 1TB model we tested pairs that speed with 600 TBW endurance and a 5-year warranty, so it's built to take a beating while it's busy being absurdly quick.

But here's the thing: this drive is a specialist. The 1TB capacity lands at the 55th percentile, which is fine but not exactly generous for a drive marketed at AI workloads and 8K video. And while the speed is undeniable, our data shows the portable score is a rough 23.5 out of 100. This is a desktop workstation drive, not something you're tossing in an external enclosure for travel. If you've got a PCIe 5.0 slot and heavy workloads, it's a monster. If you're just booting Windows and playing some games, you're paying for headroom you'll rarely feel.

If you're building a budget gaming PC or just upgrading an older system, skip this drive. The 1TB capacity at the 55th percentile means you're paying a premium for speed you won't feel in everyday tasks, and the portable score of 23.5 out of 100 makes it a poor choice for external use. First-time builders on a tight budget will get far more value from a PCIe 4.0 drive like the WD_BLACK SN850X, which costs less and still delivers excellent real-world performance. And if your motherboard doesn't have a PCIe 5.0 slot, there's no reason to pay the Gen 5 tax.

The Samsung 9100 PRO is the fastest 1TB drive we've tested, and it's not particularly close. The 99th percentile speed and random performance rankings tell the story: this is a drive built for people who actually need PCIe 5.0 bandwidth, not just people who want a bigger number on a spec sheet. The 600 TBW endurance and 5-year warranty mean you're not sacrificing longevity for speed. The main caveats are the middling capacity and the heatsink requirement for sustained workloads. If you're building a workstation for AI, video editing, or heavy data work, this is the drive to beat. If you're just gaming or doing everyday tasks, a good PCIe 4.0 drive will feel nearly identical for a lot less money.
