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, landing in the 98th percentile for both speed and random performance. It's expensive, with an affordability score in the 9th percentile, but owners rate it 92/100 and rave about the real-world speed gains. If you want the fastest Gen5 drive available, this is the one.

Let's talk numbers. 14,100 MB/s read and 12,600 MB/s write. That's nearly 2x what a top Gen4 drive like the WD Black SN850X can manage. Random IOPS are 1,500K read and 1,800K write, which lands in the 98th percentile. In plain English: this drive chews through everything from game loads to 8K video renders without flinching. The Micron 232-layer TLC NAND paired with DRAM cache keeps sustained performance strong, and the aluminum and copper heatsink does its job without any noisy fans.

One thing worth mentioning: those peak numbers assume a fresh out-of-box state with write cache enabled and a queue depth of 512. Real-world performance will vary depending on your system, but even with some thermal throttling under sustained load, this drive stays ahead of nearly everything else on the market. The endurance score is 57th percentile, which is fine but not exceptional. For a drive this fast, you'd expect a bit more headroom on the write endurance front.

Against the Samsung 9100 PRO, the T705 trades blows on sequential speeds but pulls ahead on random write IOPS at 1,800K. The WD Black SN850X is a Gen4 drive that costs less but tops out around 7,000 MB/s, so the T705 nearly doubles it on paper. The Kingston FURY Renegade G5 and Micron T710 are the closest Gen5 rivals, and they're all within striking distance on specs. Where the T705 stands out is the combination of 4TB capacity, the premium heatsink, and that 98th percentile random performance. The SanDisk WD_BLACK SN8100 is another Gen5 option, but it doesn't match the T705's write speeds. If you're already on a Gen5 platform with a Ryzen 7000 or Intel 13th/14th gen CPU, the T705 is the one to beat.

The T705 4TB runs between USD 698 and USD 800 across US retailers, a spread of USD 102. Best Buy has the lowest price at USD 698, so if you're buying in the US, that's the one to grab. In Europe, prices range from EUR 736 to EUR 812, a EUR 76 gap depending on the country. Either way, you're paying a hefty premium for Gen5 speed. The affordability percentile is 9th, which tells you everything. This is not a value play. It's a performance play. If you need 4TB of the fastest storage available, the price per gigabyte is actually not terrible compared to other Gen5 drives, but you can get a very good Gen4 4TB drive for significantly less.

The Crucial T705 4TB hits 14,100 MB/s sequential reads and 12,600 MB/s writes, which puts it in the 98th percentile for speed in our database. That's the kind of number that makes Gen4 drives look like they're standing still. Random performance is just as wild: 1,500K read IOPS and 1,800K write IOPS, also 98th percentile. If you're moving huge files or hammering a database, this thing barely breaks a sweat.

But here's the catch. The affordability score sits at the 9th percentile, which means you're paying a serious premium for all that speed. The 4TB capacity is great, the 5-year warranty is solid, and the Micron 232-layer TLC NAND with DRAM cache is a proven combo. Just know that this is a halo product for people who want the absolute fastest storage money can buy right now.

If you're on a Gen4 or Gen3 platform, you won't see anywhere near the 14,100 MB/s this drive is capable of, so you're paying a huge premium for performance you can't use. The affordability score is 9th percentile, which means there are plenty of excellent Gen4 4TB drives for significantly less money. The endurance rating is only 57th percentile, so if you're doing heavy sustained writes every day, a drive with better write endurance might serve you better. And if you need something for a laptop or portable setup, the 23.9/100 portable score tells you this isn't the right tool. This is a desktop enthusiast drive, full stop.

The Crucial T705 4TB is the fastest SSD we've tested in this category, and the user sentiment score of 95th percentile backs that up. Owners consistently report massive performance gains over previous drives, easy installation, and effective cooling. The 92/100 sentiment score from real buyers tells the story: people who buy this drive love it. The only real complaints are the tricky heatsink removal and the price. If you want the absolute best Gen5 storage right now and you have the budget, this is it. Just make sure your motherboard has a Gen5 M.2 slot, otherwise you're leaving performance on the table.
