Crucial 4TB SSD PCIe 5.0 NVMe M.2

The Crucial T705 4TB hits 14,100 MB/s reads and 12,600 MB/s writes, putting it in the 98th percentile for speed in our database. It's the fastest consumer SSD we've tested, with random performance to match. But affordability is in the 9th percentile, so you're paying a serious premium for that top-tier speed.

Let's talk numbers, because this drive is basically a benchmark flex. Sequential reads of 14,100 MB/s and writes of 12,600 MB/s put it at the top of our charts. Random performance is equally absurd: 1,500K read IOPS and 1,800K write IOPS, both landing in the 98th percentile. That's the kind of throughput that makes DirectStorage workloads actually matter. Crucial claims up to 15% faster AAA game loading compared to their Gen4 drives, and based on what we're seeing, that tracks.

The Micron 232-layer TLC NAND paired with DRAM cache keeps things snappy even when the drive is getting hammered. The aluminum and copper heatsink does real work here. Under sustained load, this thing stays cool enough to avoid thermal throttling, assuming your case has decent airflow. One thing to note: the heatsink is not glued on, but several owners report that removing it feels sketchy. You have to flex the drive to separate it, which is not a great feeling when you just dropped this much cash on it.

Against the Samsung 9100 PRO, the T705 trades blows on sequential speeds but pulls ahead on random write IOPS at 1,800K. The SanDisk Black SN850X and WD_BLACK SN850X are both excellent Gen4 drives, but they top out around 7,000 MB/s, which is half what the T705 delivers. The Kingston FURY Renegade G5 is the closest Gen5 competitor, and while it's competitive on paper, the T705's heatsink solution and Micron NAND give it a slight edge in sustained workloads. The Micron T710 is essentially a sibling drive with similar internals, so if you see it cheaper, it's worth a look. The real question is whether you need Gen5 at all. If you're still on a Gen4 board, the SN850X gets you 90% of the real-world experience for a lot less money.

Here's where it gets tricky. The T705 4TB ranges from USD 698 to USD 800 across US retailers, a USD 102 spread that's worth paying attention to. The best deal we're seeing is at the USD 698 mark, so shop around before you commit. In Europe, prices run from EUR 736 to EUR 812, with the low end being the obvious pick. For context, you can grab a solid Gen4 4TB drive for significantly less, and most people won't notice the difference outside of very specific workloads. But if you're building a high-end rig with a 13th or 14th gen Intel or Ryzen 7000 CPU and you want the fastest storage money can buy, the premium starts to make sense. Just know you're paying early-adopter tax.

The Crucial T705 4TB is the fastest consumer SSD we've tested, full stop. Sequential reads hit 14,100 MB/s and writes land at 12,600 MB/s, which puts it in the 98th percentile for both speed and random performance in our database. That's nearly double what the previous-gen Crucial T500 manages at 7,400 MB/s. If you're coming from a SATA drive, one owner reported their cold boot time dropped from seventeen seconds to fifteen. That's not a typo, it's just what happens when your storage stops being the bottleneck.

But here's the thing: this drive costs real money. Affordability sits in the 9th percentile, which is a polite way of saying it's one of the most expensive drives we track. You're paying for the privilege of being on the bleeding edge, and for most people, that edge is still pretty theoretical. The 4TB capacity is nice, but endurance is only middle of the pack at the 57th percentile. This is a specialist's drive wearing a consumer price tag.

If you're still on a PCIe 4.0 or 3.0 motherboard, skip this drive. You'll be paying for Gen5 speeds you can't actually use, and the backward compatibility means you'll be leaving most of that 14,100 MB/s on the table. Also skip it if endurance matters more than raw speed. The 57th percentile endurance rating means there are cheaper drives that will likely outlast this one. And if you're building a portable setup, the 22.9/100 portable score tells you everything you need to know. This is a desktop enthusiast drive, not a road warrior.

The Crucial T705 4TB is the fastest SSD we've ever tested, and the user sentiment backs that up with a 92/100 score. Owners rave about the speed, easy installation, and effective cooling. The gripes are minor: heatsink removal is fiddly and the heatsink version costs extra. If you're building a top-tier gaming or creative workstation and you want zero storage bottlenecks, this is the drive to buy. Just make sure you're actually going to use the speed, because the price premium is steep and the endurance is only average.
