SIX X7400 1TB PCIe 4.0 NVMe M.2 2280 SSD (with heatsink)

Quick take

The SIX X7400 is a 1TB M.2 2280 NVMe SSD built for PCIe Gen4x4 systems, targeting fast real-world tasks like game loading and large file transfers. It includes a heatsink and installation items, which makes upgrading simpler, especially for PS5 or desktop/laptop storage expansion. The main catch is that PCIe Gen3 slots limit speeds, so you will not see the advertised Gen4 performance unless your device supports PCIe Gen4.

Pros and cons

Pros

  • Designed for PCIe Gen4x4 with a listed max read speed up to 7350MB/s.
  • Includes a heatsink and common install extras (helps with thermal management and setup).
  • 1TB capacity is a practical upgrade size for gaming libraries and everyday storage needs.
  • Buyer reports commonly mention fast boot times, quick file transfers, and smooth game loading after install.

Cons

  • Full advertised speeds require a PCIe Gen4-capable M.2 slot, otherwise performance will be capped.
  • Review evidence is mostly about installation ease and everyday speed, with limited detail on sustained heavy workloads.

What buyers think

Reviewed productBuy on Amazon

Buyer feedback is broadly positive around setup and performance in typical use. Multiple reviewers describe straightforward installation, with their systems recognizing the drive quickly (including Windows 11 in one case) and reporting speeds near expectations for a PCIe Gen4 NVMe SSD. The included heatsink is also mentioned as a helpful addition, particularly for keeping temperatures stable during heavier sessions. For gaming and general productivity, buyers commonly report fast boot times, quicker file transfers, and smooth game loading, suggesting the drive performs well for day-to-day upgrades. That said, buyer-review evidence is not deep on long-duration stress behavior, so if you are focused on sustained maximum throughput under constant load, you will want to cross-check your use case with your device’s cooling and PCIe lane support.

Who this SSD is best for

  • PS5 storage expansion or console gaming upgrades where you want a fast internal M.2 NVMe drive and the bundle includes a heatsink and install items.
  • PC gamers using an M.2 2280 slot that supports PCIe Gen4, looking for faster game load times and responsive system behavior.
  • Creators and power users who move large files often (video assets, photo libraries, and software projects) and want quicker transfer times.
  • Laptop and desktop upgraders who prefer an M.2 SSD in the 2280 form factor with an included heatsink to simplify thermal setup.

Key specs that matter for buying

  • Form factor: M.2 2280 (so it must fit the slot length supported by your device).
  • Interface: PCIe 4.0, using NVMe connectivity (listed as PCIe x4 / Gen4x4).
  • Capacity: 1TB.
  • Performance targets: up to 7350MB/s read (with a listed “media speed” of 6400MB/s).
  • Heatsink: included, plus installation-related parts such as screws and a screwdriver.
  • Warranty: 5 years limited warranty.

PCIe Gen3 vs Gen4 compatibility (the speed reality check)

Reviewed productBuy on Amazon

If your system has a PCIe Gen3 M.2 slot, the SSD will not run at the full Gen4 performance ceiling. In practice, it can still be a strong upgrade because NVMe is faster than older storage options, but you should not expect top Gen4 read numbers unless your platform supports PCIe Gen4. Before buying, check your motherboard or laptop model’s M.2 support for PCIe Gen4, and confirm the slot supports M.2 2280.

Pros and cons (expanded)

Pros

  • High-speed PCIe Gen4 design: built for Gen4x4 operation and rated up to 7350MB/s read.
  • Upgrade-friendly bundle: the drive is paired with a heatsink and installation items, which reduces friction for first-time NVMe swaps.
  • 1TB capacity hits a common sweet spot: enough room for games, OS apps, and day-to-day files without immediately needing a second upgrade.
  • Buyers report tangible improvements: fast boot, quick transfers, and smooth game loading show up repeatedly in review themes.

Cons

  • Limited-speed risk on Gen3-only systems: it is designed for Gen4, so you should verify your device before expecting the highest numbers.
  • Limited detail on sustained testing: most review themes focus on everyday performance and installation, not long-duration heavy-write workloads.

Value verdict

If you have a PCIe Gen4-capable M.2 2280 slot (or you are expanding PS5 storage with a compatible setup), the SIX X7400 1TB SSD looks like a practical choice. The combo of Gen4-targeted speed, 1TB capacity, and an included heatsink plus install extras makes it easier to go from “ready to upgrade” to “installed and running.” If your device is PCIe Gen3 only, it can still be worth considering, but temper expectations about peak Gen4 throughput and focus on faster general responsiveness versus chasing advertised maximum speeds.

FAQ

Reviewed productBuy on Amazon

Is this SIX NVMe SSD compatible with PCIe 3.0 systems?

It is designed for PCIe Gen4x4 operation. If you install it in a PCIe Gen3 M.2 slot, performance will be capped by the slot’s bandwidth, so you will not reach the full advertised Gen4 speeds.

What size M.2 slot does it use?

It is an M.2 2280 drive, so it requires an M.2 slot that supports the 2280 length.

Does it include a heatsink?

Yes, a heatsink is included, along with installation items such as screws and a screwdriver.

Is this SSD good for gaming on PS5 or a PC?

It is intended for gaming and is commonly used for faster game loading and smoother experience. For best results, use it in a compatible configuration, and on PC aim for a PCIe Gen4 M.2 slot to maximize performance.

What capacity is this drive?

It comes in a 1TB capacity.

What warranty comes with it?

It includes a 5-year limited warranty.
