This article covers New 2024 Crucial T705 4TB PCIe Gen5 NVMe M.2 SSD.

Overview

The Crucial T705 4TB is a PCI Express 5.0 NVMe M.2 SSD from Micron's direct consumer brand, delivering read speeds up to 14,100 MB/s and writes up to 12,700 MB/s. It stands among the fastest Gen5 SSDs available on the consumer market. With 4TB of capacity, you can store an extensive game library or handle 8K video editing projects entirely on a single drive.
This drive pairs a Phison PS5026-E26 controller with Micron's 232-layer 3D TLC NAND and 2GB of LPDDR4 DRAM cache. Random read/write performance is exceptional, making OS boot and app launches nearly instantaneous. A one-month Adobe Creative Cloud subscription is included as a nice bonus for creative professionals.
Positioned firmly at the high end, the T705 offers roughly double the bandwidth of Gen4 SSDs, making it a future-ready investment for those building cutting-edge systems. However, to unlock full performance you'll need a Gen5-capable motherboard and CPU, so check your platform compatibility before buying.

Compatibility Guide

The Crucial T705 uses the standard M.2 2280 form factor and interfaces via PCIe 5.0 x4 with NVMe 2.0. It physically fits any M.2 slot, but achieving the 14,100 MB/s read speed requires a PCIe Gen5 controller on the motherboard side. Recommended platforms include Intel 13th/14th Gen Core (Z790/Z890) and AMD Ryzen 7000/9000 series (X670E, B650E, X870E) motherboards.
When installed in a Gen4 slot, the drive will function but be limited to Gen4 speeds (~7,000 MB/s). Thermal management is critical: Gen5 SSDs run hot under sustained load, and the 4TB T705 can throttle if not properly cooled. Using a robust motherboard heatsink or an aftermarket M.2 cooler is strongly advised.

Product Info

Released in March 2024, the 4TB model sits in the premium price bracket at around ¥100,000. Crucial backs it with a 5-year limited warranty that covers the drive up to 2400 TBW. In the market, it's a clear high-end contender, competing with the Seagate FireCuda 540 and WD Black SN8100. Its headline speeds of 14,100/12,700 MB/s (read/write) place it at the top of the Gen5 chart, though real-world gains over Gen4 are situational.

Best Use Cases

  • 8K video editors and 3D rendering professionals – Large RAW files and project data load and save much faster, reducing wait times. The bundled Adobe CC subscription adds immediate value. If budget is tight, a Gen4 2TB SSD plus an external HDD combo may be more cost-effective.
  • High-end gamers building a top-tier rig – With DirectStorage becoming more common, game asset streaming is nearly instant. The 4TB capacity lets you keep almost your entire Steam library internal. However, games that fully leverage Gen5 are still scarce in 2026, so a Gen4 4TB drive may be sufficient for most users.
  • Enthusiasts who want the absolute fastest storage – If you already invested in a flagship CPU and GPU, pairing them with the fastest Gen5 SSD completes the build. For benchmark chasers and those who handle massive file transfers daily, the T705 delivers unmistakable advantages.

Things to Consider

Heat is the primary concern. Under heavy loads, the controller can exceed 70°C and throttle, hammering performance. A good heatsink and case airflow are mandatory, not optional. The drive comes without a pre-installed heatsink in this model, so plan accordingly.
Gen5 motherboards are still relatively expensive and not as widespread as Gen4 boards. If you upgrade an older PC, you'll only get Gen4 speeds, making the premium spent on the T705 hard to justify. Also, at nearly ¥100,000 for 4TB, it's a significant investment. For many, a 2TB Gen5 drive or a 4TB Gen4 drive offers better value, especially when real-world responsiveness differences are minimal.
Compared to the Seagate FireCuda 540 4TB (around 10,000 MB/s read), the T705 wins on sequential throughput but costs more. Random I/O performance is roughly comparable, so the day-to-day feel may be similar.

FAQ

Q: Can I use the T705 on a Gen4 motherboard? What speed will I get?
A: Yes, it will work in a Gen4 slot but is limited to approximately 7,000 MB/s. That's still fast, but the price premium for the T705 over a high-end Gen4 drive becomes harder to recoup.
Q: How much faster are game load times with this Gen5 SSD?
A: In DirectStorage-optimized titles, load times can be 20–30% shorter than Gen4. However, most legacy game engines don't show a noticeable difference, so don't expect a revolutionary change in everyday gaming.
Q: What is the endurance rating of the 4TB model?
A: Crucial specifies 2400 TBW for the 4TB variant. That translates to writing about 6.6 TB per day for five years, far beyond typical consumer usage. The 5-year warranty covers the drive before TBW is exhausted.
