What the X7400 package actually offers
The SIX X7400 reviewed here is the 1TB PCIe Gen4x4 NVMe M.2 2280 configuration supplied with a heatsink. Its value proposition combines a claimed read-speed ceiling of 7,350MB/s, an installation accessory bundle and a five-year limited warranty. SIX markets it for laptop, desktop and PS5 storage expansion, giving it several potential roles rather than a single dedicated platform.
This is a specification-based assessment of the supplied retailer listing, not a hands-on test. The package has appealing headline features, but the evidence is much thinner on sustained performance, component selection and physical clearance with the heatsink. For a gaming upgrade, the central question is therefore not simply whether the advertised speed looks attractive: it is whether the documented configuration answers enough questions about your intended installation.

A read-speed headline, not a gaming benchmark
SIX advertises read speeds reaching 7,350MB/s. Treat that as a manufacturer-style maximum claim rather than an established result for this review. The listing does not provide a test platform, workload description or other conditions that would let a buyer judge how readily that figure translates to a particular machine.
For gaming, the useful distinction is between a transfer-speed specification and demonstrated experience. The supplied material promotes quicker loading and responsive gameplay, but it contains no game-specific results. It cannot establish how much faster a game will load compared with your current storage, nor does it support promises about frame rates or eliminating interruptions. The sensible buying rationale is storage expansion with an advertised high read ceiling, not a guaranteed transformation of every game.
The evidence also omits write-speed figures and sustained-write behavior. That matters if this drive will handle substantial file transfers alongside a game library: the headline read number does not answer those questions. SIX additionally advertises a percentage performance improvement without identifying a clear comparison baseline in the supplied material. That claim is not useful enough to anchor a buying decision.
Check the slot and the heatsink separately
The M.2 2280 designation and PCIe Gen4x4 NVMe interface identify the intended drive format. SIX’s broad laptop and desktop compatibility language should still be read as a starting point, not confirmation for every system. Before choosing it, check the host system’s documentation for the supported storage interface, drive length and installation restrictions. A product category label alone does not settle compatibility.
The included heatsink is potentially useful, but its presence creates a separate clearance question. Although the listing gives overall product dimensions, it does not say whether those measurements include the heatsink or provide an assembled height. It also does not establish whether the heatsink arrives fitted. Those omissions are particularly relevant when the drive must sit beneath a laptop cover or another cooling assembly.
PS5 expansion is an explicit advertised use, rather than an independently verified conclusion here. The supplied evidence does not include a detailed fit drawing or a documented console installation check. A console buyer should confirm the complete drive-and-heatsink dimensions against the console’s requirements before relying on the listing’s compatibility wording.
If this is part of choosing an upgradeable portable system, our gaming laptop buying guide provides a broader starting point. For this SSD, however, the individual laptop’s storage documentation remains the relevant fit check.
Included accessories help, but documentation limits confidence
SIX lists a screw, screwdrivers and a heatsink among the installation accessories. That is a practical advantage for someone who does not already have the necessary small tools or cooling hardware. It makes the package more complete on paper than a drive-only offering, although the listing does not establish that every included accessory suits every host system.
The five-year limited warranty is another positive documented feature. The supplied material does not explain claim procedures, regional coverage, exclusions or any endurance-related conditions, so the duration should not be treated as the complete warranty policy. Buyers who place substantial weight on support should check those terms rather than infer service quality from the number of years.
More broadly, the absence of NAND, controller, cache and endurance details limits informed comparison. It is not evidence that the drive uses poor components or has inadequate durability. It means the listing cannot resolve those concerns. For a secondary gaming-library drive, a buyer may prioritize capacity and installation convenience; for a workload involving frequent large writes, these unanswered specification questions deserve greater weight.
Verdict: a conditional gaming-storage shortlist option
The SIX X7400 1TB with heatsink offers a clearly identified Gen4 NVMe configuration, installation extras and a stated five-year limited warranty. Those are reasonable reasons to consider it for gaming storage expansion. Its value remains conditional on verified physical fit and your comfort with missing performance and endurance details. Shortlist it for its documented package, not for untested loading promises; seek fuller specifications if sustained writes or precisely documented compatibility drive the purchase.
