Kingston 4TB SSD PCIe NVMe M.2

The Kingston KC3000 4TB is a top-tier PCIe 4.0 drive with 7000 MB/s speeds and excellent endurance. It's in the 94th percentile for random performance, making it a workstation beast. It's pricey, but worth it if you need the capacity and speed.

Sequential speeds are 7000 MB/s read and write, which is basically the ceiling for PCIe 4.0. Random IOPS hit 1000K on both reads and writes, landing it in the 94th percentile overall. That means snappy boot times, fast game loads, and zero hesitation when you're moving huge files around. The Phison E18 controller is a proven performer, and the TLC NAND keeps things consistent under sustained loads. Endurance is also a standout at 3200 TBW, so you can hammer this drive daily without worrying about wearing it out.

Against the Samsung 9100 PRO, the KC3000 holds its own on speed but Samsung has a stronger brand reputation and more social proof. The Western Digital Black SN850X is a closer match on performance and often comes in cheaper, though the Kingston's endurance rating is higher. The Crucial T700 is a Gen5 drive, so it's faster on paper, but you'll need a Gen5 motherboard to take advantage of it. The Seagate FireCuda 530R is another solid Gen4 option, but the KC3000's random performance gives it an edge for workstation tasks.

Pricing is all over the place depending on where you shop. In the US, you'll see it listed between $746 and $970, with Newegg offering the lower end of that range. In Canada, the spread is even wider at CAD 970 to CAD 1,370, and Memory Express has the best deal there. For a 4TB Gen4 drive with this level of endurance, the lower end of those ranges is actually reasonable. But at the top end, you're paying a premium that's hard to justify unless you absolutely need the capacity and speed right now.

The Kingston KC3000 is a 4TB PCIe 4.0 drive that hits 7000 MB/s on both reads and writes. That's the headline. It's built on a Phison E18 controller with TLC NAND, and Kingston backs it with a 3200 TBW endurance rating and a 5-year warranty. For a big, fast work drive, those are serious numbers.

Our database puts this thing in the 94th percentile for random performance and 93rd for endurance. It's a workstation monster. The catch? Affordability sits at the 10th percentile, so you're paying for all that speed and capacity. If you need 4TB of top-tier Gen4 storage, this is one of the best options out there.

If you're just gaming or doing light productivity work, save your money and get a 2TB drive. The price premium for 4TB is steep, and you likely won't notice the difference. Also skip this if you need a portable drive, since it scores just 21.3/100 for portable use.

If you're building a high-end workstation or gaming rig and need 4TB of fast, reliable storage, the KC3000 is an easy recommendation. It's one of the best Gen4 drives we've tested for random performance and endurance. Just make sure you're getting it at a good price, because the premium over smaller drives is significant.
