Crucial 4TB SSD PCIe 5.0 NVMe

The Crucial T705 4TB hits 14,100 MB/s reads and 12,600 MB/s writes, making it the fastest drive in our database. It's in the 98th percentile for speed and 100th for features. You'll pay for it though, with prices ranging from USD 698 to USD 800 and an affordability score in the 9th percentile.

Let's talk raw numbers. The T705 hits 14,100 MB/s sequential read and 12,600 MB/s write. That's not just fast, it's one of the best on the market. Random performance is equally impressive at 1,500K read IOPS and 1,800K write IOPS, putting it in the 98th percentile for random operations. For context, that means loading massive game worlds, scrubbing through 8K footage, or batch-processing renders feels nearly instant.

Under the hood you get Micron 232-layer TLC NAND and a DRAM cache, which keeps those speeds consistent even when the drive is getting hammered. The integrated aluminum and copper heatsink does real work too. Owners report effective cooling without any fan noise, which matters when you're pushing PCIe 5.0 speeds that can turn lesser drives into toaster ovens. Microsoft DirectStorage optimization is a nice bonus for gamers who want lower latency and less CPU overhead.

Against the Samsung 9100 PRO, the T705 trades blows on raw speed but the Samsung tends to run cooler under sustained load. The WD_BLACK WDS800T2XHE is a solid Gen5 alternative with a more aggressive heatsink design, though its sequential numbers don't quite match the T705's 14,100 MB/s peak. The Kingston FURY Renegade SFYRDK/4000G is a Gen4 drive that's significantly cheaper, but you're leaving roughly half the sequential performance on the table. The Micron T710 CT4000T710SSD5 is essentially a sibling drive with similar NAND, so it comes down to firmware tuning and price. For pure peak speed, the T705 is the one to beat right now.

Here's where things get real. The T705 4TB ranges from USD 698 to USD 800 across US retailers, a spread of USD 102 depending on where you shop. That's a meaningful chunk of change, so it pays to hunt for the lower end of that range. In Europe, prices run EUR 736 to EUR 812, a EUR 76 gap. The 9th percentile affordability score tells the story: this is a luxury purchase, not a value pick. You're paying for the fastest Gen5 drive on the market, and the price reflects that. If you can find it near the bottom of those ranges, the cost per gigabyte gets a lot more palatable.

The Crucial T705 4TB is the fastest SSD we've tested in this category, full stop. 14,100 MB/s sequential reads and 12,600 MB/s writes put it in the 98th percentile for speed and the 100th percentile for features. That's the kind of number that makes your old Gen4 drive look like it's running through molasses. And with 4TB of capacity, it's also in the 93rd percentile for storage space, so you're not sacrificing room for all that velocity.

But here's the catch. This thing sits in the 9th percentile for affordability. You're paying a serious premium for those top-tier numbers. The endurance rating of 2,400 TBW lands at a middling 57th percentile, which is fine but not exactly a flex for a drive this expensive. Still, if you want the absolute best right now and money isn't the main concern, the T705 delivers exactly what the spec sheet promises.

If you're building a budget or mid-range system, look elsewhere. The 9th percentile affordability score means you're paying a huge premium for speeds most people won't notice outside of very specific workloads. The endurance rating of 2,400 TBW is only in the 57th percentile, so if you're writing massive amounts of data constantly, there are drives with better longevity per dollar. And if you plan to use your own aftermarket heatsink, the tricky removal process might make you think twice.

The Crucial T705 4TB is the fastest consumer SSD we've seen, and the data backs that up. 98th percentile speed, 100th percentile features, and a 4.4-star average from 45 reviews. Owners consistently mention huge performance gains over previous drives, easy installation, and effective cooling. The only real complaints are the tricky heatsink removal and the premium price. If you're building a top-tier rig and want zero compromises on storage speed, this is the drive to get. Just know you're paying for the privilege.
