Crucial T705 1TB PCIe 5.0 x4 NVMe M.2 2280

The Crucial T705 is one of the fastest SSDs we've ever tested, with 13,600 MB/s reads and top-tier random performance. It runs hot and costs a premium, so you need a heatsink and a real reason to buy it. If you have a PCIe 5.0 board and heavy workloads, it's worth it. Everyone else should save money and get a Gen4 drive.

The T705 absolutely rips. Sequential reads hit 13,600 MB/s and writes land at 10,200 MB/s, which is roughly double what most Gen4 drives manage. Random performance is just as impressive, with 1,400K read IOPS and 1,750K write IOPS putting it near the top of the charts. The Micron 232-layer TLC NAND and DRAM cache keep things moving even under sustained loads. But here's the thing: all that speed generates heat. Without proper cooling, this drive will thermal throttle and you'll lose the very performance you paid for. The copper-clad label helps transfer heat to a motherboard heatsink, but if your board doesn't have one, you need to budget for a third-party solution.

Against the Samsung 990 Pro and WD Black SN850X, the T705 wins on raw speed. Those Gen4 drives top out around 7,000-7,400 MB/s, so the T705 nearly doubles them in sequential throughput. The Kingston KC3000 is also a strong Gen4 option but can't touch these numbers either. Where the T705 loses ground is in social proof and brand trust. Samsung and WD have thousands of reviews and years of reliability data. The T705 has 45 reviews and a 4.5 rating, which is fine but not exactly a mountain of evidence. If you want the absolute fastest drive and have the cooling to handle it, the T705 is the pick. If you want proven reliability and better value, the 990 Pro or SN850X are safer bets.

Here's where it gets tricky. The T705 is not cheap. In the US, prices range from USD 269 to USD 335 depending on the vendor, and the best deal we found is at the lower end of that spread. In Europe, you're looking at EUR 272 to EUR 315. That's a lot of money for 1TB of storage, especially when you can get a solid Gen4 drive like the Samsung 990 Pro or WD Black SN850X for less. But if you have a PCIe 5.0 motherboard and you actually need this kind of speed for heavy creative work or DirectStorage gaming, the premium might be worth it. For everyone else, a good Gen4 drive will feel nearly as fast in daily use and cost significantly less.

The Crucial T705 is a Gen5 speed demon. We're talking 13,600 MB/s sequential reads and 10,200 MB/s writes, which puts it in the top tier of every speed metric in our database. This is the drive you buy when you want your motherboard's PCIe 5.0 slot to actually earn its keep.

It's not just fast on paper. The random IOPS numbers are wild too, 1,400K read and 1,750K write. That's the kind of performance that makes DirectStorage gaming and 8K video editing feel snappy instead of like waiting for a pot to boil. Just know that all this speed comes with a catch: heat. You'll want a decent heatsink, whether it's your motherboard's or Crucial's own premium option.

Skip the T705 if you don't have a PCIe 5.0 motherboard, because you're paying for speed you can't use. Also skip it if you're on a budget or just need a boot drive. A Gen4 drive like the WD Black SN850X or Samsung 990 Pro will save you real money and feel just as fast for everyday tasks. And if you're building in a small case with poor airflow, the heat management hassle isn't worth it.

Buy the Crucial T705 if you have a PCIe 5.0 motherboard, a proper heatsink, and a workload that actually benefits from Gen5 speeds. That means DirectStorage gaming, 8K video editing, or heavy data crunching. If you're just booting Windows and loading a few games, you won't feel the difference between this and a good Gen4 drive. The T705 is a specialist's tool, not a general-purpose upgrade.
