Crucial T705 Vs T700: Speed, Thermals & Value Compared

Both are blazing-fast Gen5 drives—T705 wins on pure speed, T700 wins on value.

I’ve lived the “which Gen5 SSD should I buy?” struggle. If you are eyeing the crucial t705 vs t700 for a new gaming rig or creator workstation, both look brilliant on paper. I tested each in the same PC, pushed big files, and played DirectStorage games. My take: both are excellent, but one offers more speed, while the other offers better value. Below I break down how the crucial t705 vs t700 feel in real use so you can pick the right fit.

Is Crucial T705 Good?

Yes. The Crucial T705 is a beast if you want the fastest Gen5 NVMe I’ve used so far. It’s ideal for power users, 8K video editors, texture-heavy game modders, and anyone who chases top numbers. If your board has a PCIe 5.0 M.2 slot and good airflow, the T705 delivers peak sequential speeds and snappy random performance that you can feel during huge transfers.

In my Z790 test bench, the T705 shaved time off 100 GB project copies versus my T700. It was not night and day in games, but it was clear in large media moves and compiles. In a DirectStorage title, asset streaming felt a touch smoother on heavy scenes. The T705 does run hot, so a proper heatsink and case airflow matter.

What Makes It Stand Out / Key Features

• PCIe Gen5 x4 NVMe performance with up to 13,600 MB/s reads (capacity dependent)
• Phison E26 controller with high-speed Micron 232-layer TLC NAND
• Strong random IOPS and snappy responsiveness under heavy queues
• DirectStorage-ready for next-gen PC games
• 5-year limited warranty and robust firmware support

What I Like

• Class-leading sequential speed for huge project moves
• Great consistency on long transfers with a healthy SLC cache
• Fast app launches and quick level loads
• Excellent for 4K/8K timelines and large RAW sets
• Feels “instant” in daily use on a modern Gen5 board

What Could Be Better

• Runs hot; a quality heatsink and airflow are a must
• Premium price versus the T700
• Benefits shrink if you only have PCIe 4.0

My Recommendation

If you want the fastest Crucial Gen5 today and have strong cooling, get the T705. It’s the speed pick.

Best For	Why
Pro creators	Top sustained writes and rapid project moves
Benchmark fans	Highest sequential numbers (Gen5 slot required)
High-end gaming PCs	DirectStorage-ready with very low latency

Is Crucial T700 Good?

Yes. The Crucial T700 is the smarter buy for most users who want Gen5 speed without the top-tier price. It’s fast, stable, and more affordable. In many day-to-day tasks, it feels just as quick as the T705. If you want top performance per dollar, the T700 shines.

I used the T700 with the heatsink in the same Z790 system. It kept temps in check during long installs and Steam library moves. Compared to my best Gen4 drive, compile times and big exports were clearly faster. In games, the T700 felt swift and smooth, and the value made it an easy choice for a second drive. For the crucial t705 vs t700 debate, this is the sensible pick.

What Makes It Stand Out / Key Features

• PCIe Gen5 x4 NVMe with up to 11,700 MB/s reads (capacity dependent)
• Phison E26 controller and proven Micron TLC NAND
• Heatsink options help control thermals under heavy load
• DirectStorage support for faster asset streaming
• 5-year limited warranty and mature firmware

What I Like

• Excellent speed for less money than T705
• Runs cooler with the factory heatsink
• Stable, reliable, and easy to drop into many Z690/Z790/X670E boards
• Great real-world boosts over fast Gen4 drives
• Strong balance of random and sequential performance

What Could Be Better

• Not as fast as the T705 at the top end
• Needs airflow; Gen5 can throttle without it
• Sustained writes can dip after the SLC cache is exhausted

My Recommendation

If you want Gen5 speed with better value, choose the T700. It’s the sweet spot.

Best For	Why
Most gamers	Great speed, lower cost, and cool operation with heatsink
Budget-conscious creators	Fast enough for 4K/6K work at a better price
Upgraders from Gen3/Gen4	Big jump in throughput without breaking the bank
