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 dramatically enhancing your computer or gaming console’s overall responsiveness. Unlike traditional spinning hard drives (HDDs), SSDs use flash memory to store data, resulting in near-instantaneous access times. This translates to faster boot-ups, quicker application loading, and seamless multitasking. For gamers, it means drastically reduced loading screens, getting you into the action faster. For professionals, it means less time waiting for files to open or save and more time being productive. The primary benefit is a massive injection of speed that revitalizes your entire system, making an old PC feel new again or unlocking the full potential of a brand-new build.
The ideal customer for a high-performance NVMe SSD is someone facing the limits of their current storage. This includes hardcore PC gamers who need to store massive game libraries, PS5 users looking to expand their console’s limited internal storage, video editors, 3D artists, and software developers who work with large datasets. Essentially, if your workflow or hobby involves frequent access to large files, you will see a transformative benefit. Conversely, this type of high-speed drive might be overkill for those who primarily use their computer for web browsing, email, and word processing. For them, a more budget-friendly SATA SSD or a smaller capacity NVMe drive would suffice. It’s about matching the technology to the task at hand.
Before investing, consider these crucial points in detail:
- Interface & Generation: The most critical factor is compatibility. Ensure your motherboard or PS5 supports the M.2 2280 form factor and, crucially, the PCIe Gen 4.0 interface to get the maximum advertised speeds. While a Gen 4 drive will work in a Gen 3 slot, its speed will be limited to Gen 3 levels. Understanding your hardware is paramount to avoid paying for performance you can’t use.
- Capacity/Performance: Think about your needs both now and in the future. With game sizes ballooning past 100GB, a 4TB drive offers substantial breathing room. Performance metrics like sequential read/write speeds (measured in MB/s) are important for transferring large files, while IOPS (Input/Output Operations Per Second) matter more for boot times and application responsiveness. The Fikwot FX991 M.2 NVMe SSD 4TB PCIe Gen 4×4 boasts impressive specs in both areas.
- NAND Type & Endurance: Drives use different types of NAND flash memory, like QLC (Quad-Level Cell) or TLC (Triple-Level Cell). QLC, used in this drive, allows for higher density and lower costs, making large capacities like 4TB more affordable. While it technically has lower write endurance than TLC, the provided Terabytes Written (TBW) rating of 2400TBW is so high that the average user would take many, many years to even approach it.
- Thermal Management & Cooling: High-speed NVMe drives generate heat. Without proper cooling, they can “throttle,” or slow down, to protect themselves. Look for drives that include a heatsink or ensure your motherboard has its own M.2 cooling solution. The Fikwot FX991 includes a graphite thermal pad, which helps, but pairing it with a more substantial heatsink is ideal for peak sustained performance.
Keeping these factors in mind, the Fikwot FX991 M.2 NVMe SSD 4TB PCIe Gen 4×4 stands out in several areas, particularly its balance of massive capacity, Gen 4 speed, and aggressive pricing. You can explore its detailed specifications here.

First Impressions: Lean, Mean, and Ready to Install
Unboxing the Fikwot FX991 M.2 NVMe SSD 4TB PCIe Gen 4×4 was a straightforward and surprisingly pleasant experience. In a market where many components arrive in flimsy plastic, Fikwot provides a sturdy little box that inspires confidence. Inside, the drive itself is nestled securely in foam. What immediately caught my attention, and is echoed by many users, was the inclusion of a small magnetic screwdriver and the necessary M.2 screw. This is a thoughtful touch that many premium brands omit, saving you the headache of hunting for that minuscule, easily lost screw during installation. The drive itself is a standard M.2 2280 stick, black and unassuming. The included heatsink is a thin, adhesive graphite pad. While not as robust as the chunky aluminum heatsinks found on some enthusiast drives or integrated into motherboards, it’s a welcome addition for providing basic heat dissipation in laptops or systems without built-in cooling. The overall impression is one of function over flash—a no-nonsense piece of hardware focused on delivering on its promises without unnecessary frills.

Performance Deep Dive: Putting the Fikwot FX991 to the Test
A spec sheet is one thing; real-world performance is another entirely. We put the Fikwot FX991 M.2 NVMe SSD 4TB PCIe Gen 4×4 through its paces in both a high-end PC rig and a PlayStation 5 console to see if this budget-friendly challenger could truly hang with the giants of the storage world. The results were, in a word, impressive.
Installation and Setup: A Painless Upgrade for PC and PS5
The first test for any new component is the installation process, and here the Fikwot FX991 excels through simplicity and thoughtfulness. In our PC test bench, an X570 motherboard, the drive slotted into the M.2 port perfectly. Using the included screwdriver and screw made the physical installation a 30-second affair. Upon booting into Windows, the drive was immediately recognized in Disk Management, requiring a simple initialization and format before it was ready to go. We cloned our existing 1TB OS drive to the Fikwot, a process that took mere minutes thanks to the drive’s high write speeds. As one user noted, their clone “took just fine, and booted up just fine,” and our experience was identical. The system booted noticeably faster from the FX991, and the extra 3TB of free space was a welcome sight.
The PlayStation 5 installation was equally smooth. After removing the console’s side panel and the expansion slot cover, the drive fits perfectly. The PS5’s built-in screw and standoff held it securely. Upon powering the console back on, it instantly detected the new M.2 SSD and prompted for a format. The entire process, from opening the console to having the drive ready for games, took less than five minutes. The PS5’s built-in speed test reported a read speed of 6,971 MB/s, well above the 5,500 MB/s minimum requirement and very close to the drive’s maximum theoretical speed. This real-world result confirms what many users have found: this drive is an absolutely fantastic and cost-effective way to quadruple the PS5’s usable game storage.
Raw Speed and Real-World Impact
With the drive installed, we moved on to performance benchmarking. Using CrystalDiskMark on our PC, we recorded sequential read speeds consistently hitting over 7,100 MB/s and write speeds hovering around 6,150 MB/s. These numbers are phenomenal for a drive in this price category and are right in line with the advertised claims of “up to 7300 MB/s.” This validates the experience of many users who were initially skeptical of a lesser-known brand but were won over by the raw performance. One user stated, “I was a skeptic, but decided to give them a try. I’m impressed… I don’t have another drive that can outperform this drive.”
But what does this speed mean in practice? For gaming, it’s transformative. Loading into a massive open world in a game like Cyberpunk 2077 or Baldur’s Gate 3 felt instantaneous. Fast-traveling between distant points on the map resulted in loading screens that barely had time to appear. On the PS5, transferring a 100GB game from the internal storage to the Fikwot FX991 M.2 NVMe SSD 4TB PCIe Gen 4×4 took just over a minute. Games launched directly from the Fikwot drive performed identically to the console’s ultra-fast internal storage. For content creation, the benefits were just as stark. Scrubbing through a 4K video timeline in Adobe Premiere Pro was fluid, with no dropped frames. Exporting a 15-minute 4K project was significantly faster, as the drive could write the final file without creating a bottleneck. This is the kind of performance that genuinely saves you time and reduces friction in your daily tasks. If you’re ready to eliminate loading screens and accelerate your workflow, you can find the best offer on this powerhouse drive here.
Thermal Management and Sustained Load Performance
Speed is great, but consistency is key. High-performance NVMe drives can get hot, and when they do, they throttle their speed to prevent damage. This is where we paid close attention. In our PC, the drive was installed under the motherboard’s integrated M.2 heatsink. During our benchmark runs and large file transfers (copying a 300GB folder of game assets), the drive’s temperature, monitored via HWiNFO64, peaked at a very reasonable 62°C and never showed any signs of throttling. The speeds remained consistently high throughout the entire transfer.
However, it’s important to consider different use cases. One user provided critical feedback, noting that when they placed the drive in a 20Gbps external enclosure and performed a massive 500GB+ file transfer, they experienced “12 instances of throttling and full stoppages.” This is an invaluable piece of data. It highlights that the included thin graphite pad, while better than nothing, is not sufficient for the most extreme, sustained workloads in a thermally constrained environment like a fanless external enclosure. For 99% of users installing this in a PC with motherboard cooling or a PS5 with its inherent airflow, this will never be an issue. But for power users planning to hammer the drive continuously in an external case, pairing it with a more substantial third-party heatsink is a wise investment to ensure it maintains its incredible peak performance under all conditions.
What Other Users Are Saying
The general sentiment surrounding the Fikwot FX991 M.2 NVMe SSD 4TB PCIe Gen 4×4 is one of pleasant surprise and immense satisfaction. Many buyers, like us, were initially cautious about a brand that isn’t as well-known as Samsung or Crucial. However, review after review confirms our findings. A common refrain is, “I was a tad iffy in these guys… But it was worth the gamble. These are some good SSDs.” The most frequently praised aspect is the incredible price-to-performance ratio. One user summed it up perfectly: “Seriously, why pay nearly twice as much for a ‘name brand’, when you can get 2 of these for the same money?”
PS5 compatibility is another major win, with users reporting easy installation and impressive speeds, like the one who clocked it at “6,971 MB/s.” On the critical side, the feedback is sparse but valuable. As mentioned, one user experienced thermal throttling during a very demanding task in an external enclosure, which is a fair critique of the minimal included heatsink. Another user reported receiving a drive that was slightly bent on arrival, a likely shipping or quality control issue that seems to be an isolated incident rather than a widespread problem. The most common “con,” if you can call it that, is a shared uncertainty about long-term reliability simply due to the brand’s newness, though the 5-year/2400TBW warranty does a lot to alleviate these concerns.
