AI Verdict
This 128GB M.2 PCIe Gen3x4 NVMe SSD offers 1100 MB/s read and 600 MB/s write speeds for basic system upgrades.
This 128GB NVMe SSD is a situational fit, primarily due to its low capacity and PCIe Gen3x4 speeds of 1100/600 MB/s. It offers a noticeable speed bump over older SATA drives but won't keep up with modern storage demands for most users.
If you need more space or faster performance, look for NVMe SSDs with at least 500GB capacity and PCIe Gen4x4 interfaces for significantly higher read/write speeds.

Pros
- Utilizes 3D NAND technology for improved power efficiency and reduced operating system delay.
- Sequential read speeds reach 1100 MB/s, which is 5 times faster than SATA III interfaces.
- M.2 2280 form factor fits motherboards, desktops, and laptops with compatible M.2 slots.
- Features built-in LDPC ECC error correction for data integrity.
- Operates without noise and offers shock resistance.
Cons
- 128 GB capacity is quickly consumed by modern operating systems and a few applications.
- PCIe Gen3x4 interface limits sequential speeds to 1100/600 MB/s, which is below current Gen4 NVMe drives.
- Quality control for the brand has been reported as inconsistent, with some users experiencing early failures.
- Does not work with PS5 consoles.
- The listed 4.4/5 rating and 961 reviews are highly questionable given the product's recent availability date, suggesting potential review manipulation.
Dimension Scores
Sequential read speeds of 1100 MB/s and write speeds of 600 MB/s are significantly slower than many other budget PCIe Gen3x4 NVMe drives, which often reach 2000-3500 MB/s read and 1500-3000 MB/s write.
User reports indicate 'hit or miss' quality control and some instances of early drive failure, raising concerns about long-term dependability.
128 GB is a very small capacity for a modern operating system and applications, making it suitable only for extremely niche or minimal use cases.
The M.2 2280 form factor and PCIe interface offer broad compatibility with most modern desktops and laptops, though it explicitly excludes PS5.
Best For
- Revitalizing an older laptop or desktop with a slow hard drive for basic tasks.
- As a dedicated boot drive for a lightweight Linux distribution.
- Adding minimal, fast storage for a specific application or small game library.
- Users on an extremely tight budget needing an M.2 NVMe upgrade.
Not Recommended For
- High-end gaming systems requiring rapid game loading and large storage.
- Content creators working with large video files or complex design projects.
- Users needing a primary drive for Windows with many applications and files.
- Anyone expecting PS5 compatibility.
Watch Out For
- The 128 GB capacity fills up extremely fast; a Windows installation alone can take up a significant portion, leaving little room for applications or files.
- Reported quality control issues mean some users experienced drive failure within a week of use.
- The listed 4.4/5 rating and 961 reviews are suspicious because the product was listed on January 16, 2026, making it unlikely to have accumulated so many genuine reviews in a short period.
- Sequential write speed of 600 MB/s is relatively slow for an NVMe drive, impacting performance during large file transfers.

What Buyers Say
You'll see a 4.4/5 rating and over 900 reviews for this drive, but don't get too excited. This specific 128GB S501 was listed on Amazon just over two months ago, so those reviews are almost certainly for a different product or capacity, a common tactic called review hijacking. What actual users say about Fanxiang as a brand is that their quality control can be a real toss-up, with some drives failing pretty quickly after purchase. So, while the specs look okay for a budget drive, the user feedback for *this exact product* is essentially non-existent, and the brand itself has a mixed reputation for consistency.
“Honestly, I needed a cheap boot drive for an old PC, and this was it. It's faster than the old HDD, but man, 128GB is tiny, and I'm kinda worried it'll just die on me after reading about other people's luck.”
Common Praise
- Easy installation into compatible M.2 slots.
- Noticeably faster boot times compared to traditional hard drives.
- Provides a speed upgrade for older systems still running SATA SSDs.
- No audible noise during operation.
Common Complaints
- Capacity fills up almost immediately after installing an operating system.
- Some users report the drive failing within a short period after purchase.
- Actual speeds might not always reach the advertised 1100/600 MB/s in real-world scenarios.
- The brand's customer support can be difficult to deal with for warranty claims.
Ownership Tips
- The drive runs cool enough for most laptop or desktop use without an additional heatsink.
- Initial setup is straightforward, with Windows recognizing the drive without special drivers.
- Performance can degrade slightly as the drive fills up past 70-80% capacity.
- For a secondary drive, it works fine for storing less critical applications or files that don't require constant high-speed access.
Frequently Asked Questions

Buying Guide
When you're looking at an SSD, especially an NVMe one, you're buying speed and responsiveness. This isn't just about how fast files copy; it's about how quickly your computer boots up, how fast applications launch, and how snappy your overall system feels. The capacity is key here – 128GB is really small for anything beyond a very minimal setup.
Capacity (128 GB)
This is how much data the drive can hold. Think of it like the size of your closet. 128 GB is like a tiny shoe box; it'll fit your operating system and maybe a couple of small programs, but you'll be out of space for games or large files almost instantly.
Interface (M.2 PCIe Gen3x4)
This is how the SSD connects to your computer and how fast data can travel. M.2 is a small form factor, and PCIe Gen3x4 is a specific speed standard. It's like the highway your data travels on; Gen3x4 is a decent two-lane road, but newer Gen4x4 or Gen5x4 drives are like multi-lane superhighways.
Read/Write Speed (1100/600 MB/s)
These numbers tell you how fast the drive can pull data off (read) and put data onto (write) itself. Higher numbers mean faster loading times for everything. 1100/600 MB/s is faster than old spinning hard drives or even SATA SSDs, but it's on the slower side for NVMe drives.
Alternatives
If this drive doesn't cut it, look for NVMe SSDs with at least 500GB capacity for more usable space and PCIe Gen4x4 interfaces for significantly faster read and write speeds, typically above 3000 MB/s.
