I remember the exact moment I knew my old storage drive had to go. I was deep into a session of a graphically intense open-world game, right at a critical story moment. The screen froze, the dreaded loading icon appeared, and the immersion was shattered. It wasn’t just gaming; editing 4K video footage felt like wading through digital mud. Every click on the timeline was met with a pause, a stutter, a spinning wheel of death that tested my patience to its limits. This isn’t just an inconvenience; it’s a bottleneck that strangles creativity and turns entertainment into frustration. In today’s fast-paced digital world, waiting for files to load or applications to launch is lost time and lost momentum. The culprit is almost always outdated storage technology, unable to keep up with the demands of modern software, massive game files, and high-resolution media.

What to Consider Before Buying an Internal Solid State Drive
An Internal Solid State Drive is more than just an item; it’s a key solution for breathing new life into a sluggish computer or expanding the capabilities of a gaming console. Unlike traditional hard disk drives (HDDs) with their spinning platters and moving parts, Solid State Drives (SSDs) use flash memory to store data, resulting in exponentially faster read and write speeds. This translates directly to a snappier, more responsive user experience. Your operating system will boot in seconds, applications will launch instantly, and in-game loading screens that once felt like an eternity will become a distant memory. For content creators, this means smoother playback and rendering. For gamers, it means getting into the action faster. For the average user, it means a significant and immediately noticeable quality-of-life improvement across the entire system.
The ideal customer for this type of product is someone facing performance bottlenecks: the PC gamer tired of long load times, the video editor struggling with choppy 4K timelines, the software developer compiling large projects, or even the PlayStation 5 owner looking to expand their game library without compromise. However, a high-speed NVMe drive might not be suitable for those who simply need bulk archival storage for photos or documents where speed is not a primary concern. In those cases, a larger, more affordable traditional HDD or a slower SATA SSD might be a more cost-effective solution. It’s also not for users with older motherboards that lack an M.2 slot; they would need to look at 2.5-inch SATA SSDs instead.
Before investing, consider these crucial points in detail:
- Interface & Compatibility: This is the most critical factor. Modern high-speed drives like the SIX use the M.2 form factor and a PCIe 4.0 (Gen4) NVMe interface. You must ensure your motherboard or PS5 has a compatible M.2 slot. While a Gen4 drive is backward compatible with a PCIe 3.0 (Gen3) slot, its speeds will be limited to about 3,500 MB/s, effectively cutting its performance in half. Always check your system’s specifications before purchasing.
- Performance & Speed: Look at the advertised sequential read and write speeds, measured in megabytes per second (MB/s). For a PCIe 4.0 drive, you should expect speeds well above 5,000 MB/s. These numbers directly impact how quickly large files transfer and games load. Also, consider the drive’s controller and NAND type, as these components influence sustained performance and longevity, although this information isn’t always front-and-center.
- Thermal Management: High-speed NVMe drives generate significant heat, especially under sustained load. Excessive heat can cause the drive to “throttle,” or slow down, to protect itself. It’s essential to have a solution for heat dissipation. Many motherboards have built-in M.2 heatsinks, but a drive that includes its own, like this one, offers great value and ensures you have what you need.
- Capacity & Endurance: Choose a capacity that meets your needs. 1TB is a sweet spot for many, offering enough space for an operating system, several large games, and applications. Also, look for the warranty period (a 5-year warranty is a good sign of manufacturer confidence) and the Terabytes Written (TBW) rating if available, which indicates the drive’s endurance over its lifespan.
Keeping these factors in mind, the SIX 1TB NVMe M.2 SSD PCIe 4.0 with Heatsink stands out in several areas, particularly its combination of top-tier speed and included thermal solution. You can explore its detailed specifications here.
While the SIX 1TB NVMe M.2 SSD PCIe 4.0 with Heatsink is an excellent choice, it’s always wise to see how it stacks up against the competition. For a broader look at all the top models, we highly recommend checking out our complete, in-depth guide:

First Impressions: A Complete Kit from an Unfamiliar Name
Admittedly, when the SIX drive arrived at our lab, the brand name wasn’t one we were familiar with. In a market dominated by giants like Samsung, Crucial, and Western Digital, a new player always invites a healthy dose of skepticism. However, the unboxing experience immediately began to assuage those concerns. The drive came securely packaged in a professional retail box. Inside, we found not just the M.2 stick itself, but a surprisingly comprehensive installation kit. This included a perfectly sized heatsink with a thermal pad, a small magnetic screwdriver, the necessary M.2 screw, and even cleaning wipes. This is a thoughtful touch that many bigger brands neglect, forcing users to hunt for a tiny screw or buy a separate heatsink. For a first-time builder or someone performing a quick upgrade, this all-in-one package is a massive convenience. The drive itself feels well-made, adhering to the standard M.2 2280 form factor. The included aluminum heatsink has a clean, low-profile design that should fit comfortably in tight spaces, including the PS5’s expansion slot.

Performance Deep Dive: Putting the SIX X7400 to the Test
A spec sheet is just a promise. To find out if the SIX 1TB NVMe M.2 SSD PCIe 4.0 with Heatsink could deliver on its claims of 7,350 MB/s reads and 6,400 MB/s writes, we subjected it to a rigorous battery of both synthetic benchmarks and real-world scenarios. We tested the drive on a modern platform featuring an AMD B550 motherboard and a Ryzen 7 processor, ensuring we had a full PCIe 4.0 x4 M.2 slot to eliminate any potential bottlenecks. The results were, in a word, impressive.
Installation and Setup: A Surprisingly Complete Package
The installation process was refreshingly straightforward, largely thanks to the included accessories. In our PC test rig, we first used the included wipes to clean the drive’s surface, applied the thermal pad, and then snapped the aluminum heatsink into place. It was a snug, secure fit. From there, it was a simple matter of inserting the M.2 drive into the motherboard slot and using the provided screwdriver and screw to secure it. For beginners, the inclusion of these small parts is a game-changer, preventing the frustrating search for a misplaced motherboard screw. As one user noted, “Installation was simple, it came with tools, hardware, cleaning wipes, and a heatsink!” This sentiment perfectly mirrored our experience. After booting into Windows, the drive wasn’t immediately visible in File Explorer, which is standard procedure. A quick trip to Windows Disk Management allowed us to initialize and format the drive, after which it appeared as a usable 931GB volume (the expected capacity after formatting). The process was identical for a laptop upgrade, though it required opening the laptop’s chassis. For PS5 users, the process is just as simple: pop off the side panel, open the expansion slot cover, and install the drive. The low-profile heatsink fits perfectly within Sony’s specifications.
Benchmark Breakdown: Hitting the Advertised Speeds
With the drive installed, we fired up CrystalDiskMark, a popular storage benchmarking tool, to see the raw numbers. We ran the test multiple times to ensure consistency and were consistently met with results that validated the manufacturer’s claims. Our sequential read speeds hovered right around 7,400 MB/s, slightly exceeding the advertised 7,350 MB/s. Sequential write speeds were equally robust, averaging around 6,500 MB/s, again beating the spec sheet. These numbers firmly place the SIX 1TB NVMe M.2 SSD PCIe 4.0 with Heatsink in the upper echelon of consumer PCIe 4.0 drives. Our findings were corroborated by several users, with one reporting, “Speeds were fast and reliable with reads at 7200 MBs and writes nearing 6000 MBs,” and another stating their tests showed, “Around 7400 MB/s read speed and 6500 MB/s write.”
It’s crucial to address the users who reported slower speeds. In nearly every case, this is due to a hardware limitation, not a faulty drive. As one insightful user explained, “Those that are getting lower speeds keep in mind this is Gen 4, you will be able to use it on outdated mobo but performance will be hindered.” Installing this drive in a PCIe 3.0 slot will cap its performance at roughly 3,500 MB/s. While this is still incredibly fast compared to a SATA SSD, it’s not the full potential. To unleash the drive’s true power, a compatible PCIe 4.0 motherboard is non-negotiable. For those planning a future system upgrade, buying a Gen4 drive now is excellent future-proofing.
Real-World Performance: Beyond the Benchmarks
Synthetic benchmarks are great for comparison, but real-world usage is what truly matters. We moved our Steam library over to the SIX drive and immediately noticed a dramatic difference. Loading into a complex area in a game like Cyberpunk 2077 or fast-traveling across the map in Baldur’s Gate 3 was significantly faster than on our previous Gen3 drive. The frustrating pauses and texture pop-in that can plague slower storage were virtually eliminated. This drive is a legitimate competitive advantage in games where loading times matter.
Next, we tested its mettle in content creation. We loaded a 15-minute 4K video project into DaVinci Resolve. Scrubbing through the timeline, which previously caused stutters and dropped frames, was now buttery smooth. Generating optimized media and rendering the final project saw a noticeable reduction in time. One user confirmed this, noting, “It’s also brilliant for 4K/8K video editing as I’ve seen significant improvements in that everything runs much smoother now.” We also tested a large file transfer, moving a 480GB folder of mixed media files from another NVMe drive. The entire operation completed in just under 10 minutes, showcasing incredible sustained write performance, a feat one power user happily confirmed in their own testing. If your daily tasks involve moving, loading, or saving massive files, this drive will fundamentally change your workflow for the better.
Thermal Management and Sustained Performance
High speeds generate high heat, and without proper cooling, an NVMe drive will throttle its performance to prevent damage. We monitored the SIX drive’s temperatures closely during our most intensive tests, including a full-drive write and extended benchmark loops. With the included heatsink installed, the drive’s temperature remained well within a safe operating range, peaking at around 62°C under the heaviest load. More importantly, we observed no thermal throttling whatsoever. The performance remained consistent from the beginning of the test to the end. This demonstrates that the included heatsink isn’t just a cheap throw-in; it’s a functional and necessary component that effectively dissipates heat and allows the drive to maintain its peak performance when it matters most. For PS5 installations or in PC cases with limited airflow, using the included heatsink is not just recommended, it’s essential for getting the performance you paid for.
What Other Users Are Saying
The general consensus among users is one of pleasant surprise and satisfaction. Many, like us, were initially skeptical of the unfamiliar brand but were won over by the raw performance and excellent value. A common thread in positive feedback is the drive’s speed, with one user stating, “This is a high-performance Gen4 NVMe SSD… and wow does it deliver.” The all-inclusive installation kit is another frequently praised feature, making the upgrade process accessible even for less experienced builders. One user summed it up perfectly: “Installation was straightforward, and the card comes with all the necessary hardware, including a heatsink and cleaning pads—everything you need for most installations.”
However, the feedback isn’t universally perfect. The most common “negative” point is from users who installed the drive in a PCIe 3.0 system and were disappointed not to see Gen4 speeds, highlighting the need for buyers to understand their own hardware’s capabilities. A more specific critique came from one user who was “Very disappointed with the random write speed,” suspecting it was due to the controller or NAND choice. While our tests didn’t reveal any alarming issues in this area for typical gaming and creative workloads, it’s a point to consider for users with very specific, IOPS-intensive server or database tasks.
