This article covers Crucial T705 PCIe Gen5 NVMe 4TB SSD ヒートシンク付き 最大14.

Overview

The Crucial T705 CT4000T705SSD5 is a PCIe 5.0 NVMe SSD featuring Micron's latest TLC NAND, delivering sequential read speeds up to 14,100MB/s and write speeds up to 12,600MB/s. Designed for enthusiasts and professionals, this 4TB drive comes with an integrated aluminum and copper heatsink to manage thermal output under sustained loads. Targeting the highest tier of consumer storage, the T705 is optimized for Intel 13th/14th Gen and AMD Ryzen 7000 series platforms with dedicated M.2 Gen5 slots. It also includes a one-month Adobe Creative Cloud All-Apps subscription, making it an attractive option for creative workflows. In the market, the T705 sits at the top of the Gen5 SSD hierarchy, competing directly with the Samsung 990 Pro and WD Black SN850X in terms of raw speed, but offering significantly higher sequential throughput. The 4TB capacity makes it a premium choice for users who need both speed and space.

Compatibility Guide

Form factor: M.2 2280 (single-sided) – fits most modern laptops and desktops. Interface: PCIe 5.0 x4 (backward compatible with PCIe 4.0 and 3.0, but at reduced speeds). Supported sockets: Intel LGA1700 (12th/13th/14th Gen) and AMD AM5 (Ryzen 7000/8000) with a CPU-attached M.2 Gen5 slot. Recommended: Use the primary M.2 slot (usually labeled M.2_1) that connects directly to the CPU for maximum Gen5 bandwidth. Chipset-connected slots top out at Gen4. * Power: The drive draws power from the PCIe slot; no additional power cable is needed. However, Gen5 SSDs can draw up to 11W, so motherboard VRM cooling and case airflow should be considered.

Product Info

Release: Early 2024. Price: Approximately ¥120,000 (around $800) for the 4TB model as of July 2026. Warranty: 5-year limited warranty (with optional registration). Distribution: Major online retailers and electronics stores. The T705 is positioned as a high-end enthusiast/professional drive. It uses Micron's 232-layer TLC NAND and a Phison PS5026-E26 controller, similar to other Gen5 flagships, but Crucial has tuned the firmware for peak sequential performance. Compared to Gen4 drives, the T705 offers roughly 40% faster sequential reads, though real-world gains depend on workload.

Best Use Cases

Hardcore gamers and early adopters: For those who want the fastest possible load times and are building a cutting-edge rig with a Gen5-capable motherboard. The T705 future-proofs your system for DirectStorage titles. However, current games rarely benefit from Gen5 speeds, so only invest if you have budget to spare. Professional video editors and 3D artists: Working with 8K+ RAW footage, large After Effects projects, or complex 3D scenes. The high sequential write speed (12,600MB/s) dramatically reduces export and render times. The included Adobe CC subscription is a nice bonus for new users. Data scientists and AI researchers: Loading large datasets (e.g., image libraries, model checkpoints) into GPU memory. The Gen5 bandwidth reduces idle GPU time during data loading, improving training pipeline efficiency. The 4TB capacity also handles multiple datasets without external drives. Who should NOT buy: Budget-conscious gamers, office users, or anyone whose motherboard lacks a Gen5 slot. If your workload is limited to web browsing, office apps, or casual gaming, a Gen4 or even Gen3 SSD will be more cost-effective.

Things to Consider

Motherboard requirement: To unlock full Gen5 speed, you need a CPU with Gen5 lanes and a motherboard that provides a dedicated M.2 Gen5 slot. Intel Z790/Z890 and AMD X670E/B650E chipsets are required. Using a Gen4 slot halves the bandwidth to ~7,000MB/s, which defeats the purpose of buying this premium drive. Thermal management: The integrated heatsink is effective, but in poorly ventilated cases, the drive may still throttle. Expect idle temperatures around 50°C and load temperatures up to 80°C. Ensure your case has good airflow around the CPU area. Some motherboards have large M.2 heatsinks that might interfere with the drive's own heatsink; check clearance before purchasing. Overkill for most users: Unless you regularly transfer massive files or work with 8K video, the T705's speed advantage over a high-end Gen4 drive like the Samsung 990 Pro (7,450MB/s) is negligible in everyday tasks. Game load times are barely faster. Consider your actual workflow before spending the premium. Price: The 4TB model costs roughly double the price of a comparable Gen4 4TB SSD. For the same money, you could get a 2TB Gen5 drive plus a 2TB Gen4 drive, offering more flexibility. Evaluate whether the additonal speed is worth the cost. ## FAQ
Q: Can I use this SSD in a PlayStation 5? A: Physically, yes, but the PS5 only supports PCIe Gen4, so the drive will run at Gen4 speeds (~7,000MB/s). The heatsink may also be too thick for the PS5 expansion bay. For PS5, a Gen4 SSD like the Crucial P5 Plus is a better fit. Q: Does this drive supp
