Micron 4TB SSD PCIe 5.0 NVMe M.2

The Crucial T705 4TB hits 14,100 MB/s reads and 12,600 MB/s writes, landing in the 98th percentile for speed in our database. It's the fastest Gen5 drive we've tested, with 4TB of capacity and a heatsink that actually works. Just be ready to pay for it, affordability sits at the 9th percentile.

Let's talk numbers. 14,100 MB/s sequential read and 12,600 MB/s sequential write are the headline specs, and they're not marketing fluff. Random performance is equally impressive: 1,500K read IOPS and 1,800K write IOPS put this drive in the 98th percentile for random operations. That's the kind of speed that makes DirectStorage games load noticeably faster and makes scrubbing through 8K footage feel smooth instead of stuttery.

The TLC NAND paired with DRAM cache means sustained performance holds up under heavy workloads. The heatsink does real work here too. Gen5 drives run hot, and Crucial's aluminum and copper design keeps thermals in check without resorting to a noisy fan. One owner reported cutting their cold boot time from seventeen seconds to fifteen after moving their OS to this drive. That's a real-world gain you can feel every time you power on.

Against the Samsung 9100 PRO, the T705 holds its own on raw speed but Samsung has stronger brand recognition and likely better social proof. The Kingston FURY Renegade G5 is another Gen5 contender that trades blows on sequential reads, but the T705's random performance at the 98th percentile gives it an edge for mixed workloads. The WD_BLACK WDS800T2XHE is a solid alternative if you want a gaming-focused drive with a different heatsink design, though its specs don't quite match the T705's top-end numbers. The Crucial T500 is the budget-friendly sibling, a Gen4 drive that costs significantly less but can't touch these speeds. And the Seagate FireCuda 530R is a Gen4 drive too, so it's not really in the same conversation for raw throughput. If you want the fastest 4TB Gen5 drive on the market, the T705 is the one to beat.

Here's where it gets real. The T705 4TB ranges from USD 698 to USD 800 across US retailers, a spread of USD 102 depending on where you shop. Best Buy has the lowest price at USD 698, so if you're buying in the US, that's the deal to grab. In Europe, prices run from EUR 736 to EUR 812, with the best deal at EUR 736. This is a premium product with a premium price tag, and the affordability percentile confirms it: 9th percentile means almost everything else in our database costs less. But you're paying for the absolute best Gen5 performance available right now, plus 4TB of capacity. If you need both speed and space, the price per gigabyte starts to make more sense.

The Crucial T705 4TB is the fastest SSD we've tested. 14,100 MB/s sequential reads and 12,600 MB/s writes put it in the 98th percentile for speed in our database, and its feature set lands at the very top of the charts. This is a Gen5 drive that actually delivers on the promise, assuming your motherboard has a PCIe 5.0 M.2 slot to feed it. The included aluminum and copper heatsink keeps things cool without adding fan noise, and you get a 5-year warranty to back up the 4TB of TLC NAND with DRAM cache.

But here's the thing: this drive is expensive. Affordability sits at the 9th percentile, which means you're paying a serious premium for that top-tier performance. The 4TB capacity is a standout at the 93rd percentile, so you're getting both speed and space in one package. If you're building a high-end gaming rig or a workstation for 8K video editing, this is the drive to beat. If you're just browsing the web, you're overspending by a lot.

Skip this drive if you don't have a PCIe 5.0 M.2 slot. You'll be paying top dollar for speeds your motherboard can't deliver. Also skip it if you're on a budget, the 9th percentile affordability ranking means there are plenty of Gen4 drives that cost half as much and still feel fast for everyday use. And if you plan to swap the heatsink for a custom cooling solution, be warned: multiple owners describe the removal process as nerve-wracking. The endurance rating at the 57th percentile is also worth noting if you're doing heavy sustained writes day in and day out, there are drives with better write longevity ratings.

The Crucial T705 4TB is the best Gen5 SSD we've tested, and the numbers back that up. 98th percentile speed, 98th percentile random performance, and 100th percentile features make it the clear choice for enthusiasts and professionals who need maximum throughput. The 92/100 user sentiment score confirms owners are thrilled with the real-world performance gains. The only real downsides are the price and the fiddly heatsink removal if you want to use your own cooling solution. If you have a PCIe 5.0 motherboard and the budget for it, this is the drive to buy.
