Pros
- Achieves sequential read/write speeds up to 5000/4800MB/s, leveraging PCIe Gen4 technology for faster data transfer.
- Includes an attachable 1mm thick aluminum heatsink designed to reduce temperatures by up to 10%.
- Utilizes 3D NAND technology, which typically offers increased storage capacity and lower power consumption compared to 2D NAND.
- Features AES 256-bit Hardware-based Encryption for enhanced data security.
- Designed with a minimal M.2 2280 form factor and slim heatsink for installation in desktops, mini PCs, and laptops.
Cons
- Multiple users reported the Realtek RTS5772DL controller as 'buggy' and causing performance issues.
- Several reports indicate the drive runs 'incredibly hot' despite the included heatsink.
- Lacks dedicated DRAM, relying on Host Memory Buffer (HMB) which can impact sustained performance.
- Multiple user accounts detail drive failures, with some units becoming read-only after 6-8 months of use.
Dimension Scores
Offers sequential speeds of 5000/4800MB/s, which is average for an entry-level PCIe Gen4 drive but not top-tier.
Multiple user reports indicate premature failures and the drive becoming read-only after several months of use.
1TB is a common and practical capacity for a primary or secondary drive in most modern systems.
The M.2 2280 form factor and slim, attachable heatsink ensure broad compatibility with desktops, laptops, and mini PCs.
Best For
- Budget-conscious users needing a Gen4 NVMe for light tasks or secondary storage, where sustained high performance isn't critical.
- Systems with good airflow that can mitigate potential heat issues.
- Users who prioritize initial purchase price over long-term reliability and peak performance.
Not Recommended For
- Primary drive for critical data or operating systems due to reported reliability concerns.
- Workstations or gaming rigs requiring consistent, high-speed, and sustained read/write operations.
- Users who cannot tolerate potential drive failures or data loss.
Watch Out For
- The drive has been described as 'buggy' by users, with its Realtek RTS5772DL controller potentially leading to inconsistent performance.
- Reports indicate the SSD can run 'incredibly hot', which might lead to thermal throttling and reduced performance over time.
- Several users experienced drive failures, with one reporting the SSD becoming read-only after 8 months.
- Performance is considered 'poor for a TLC drive' by some users, suggesting it might not meet expectations for its class.

What Buyers Say
The most concerning feedback is the recurring reports of drive failures, with some users experiencing their SSDs becoming read-only after only 6-8 months. There are also consistent complaints about the Realtek controller being buggy and the drive running excessively hot, even with the included heatsink. While it offers decent speeds for a Gen4 drive, these reliability and performance consistency issues overshadow its value proposition.
“Man, this thing died on me after like 7 months, just went read-only out of nowhere. Lost all my game saves, seriously frustrating. Never again with this brand.”
Common Praise
- The initial speeds are fast enough for general use and game loading.
- The included heatsink is a useful addition for temperature management.
- It's an affordable option for a PCIe Gen4 NVMe SSD.
- Installation is straightforward due to the standard M.2 2280 form factor.
Common Complaints
- The Realtek RTS5772DL controller is frequently described as 'buggy'.
- The drive runs 'incredibly hot' under load, potentially leading to thermal throttling.
- Multiple instances of the SSD failing or becoming read-only after a few months.
- Performance is considered 'poor for a TLC drive' by some users, especially for sustained tasks.
Ownership Tips
- The drive might show signs of health degradation rapidly after a few months of use.
- Expect potential issues with the drive becoming read-only, preventing further writes.
- Performance might degrade significantly during prolonged transfers or heavy use due to heat and the DRAM-less design.
- Warranty claims might be necessary, so keep your purchase records.
Frequently Asked Questions
Does this SSD come with a heatsink?
Yes, it includes an attachable 1mm thick aluminum heatsink designed to help dissipate heat.
What kind of speeds can I expect?
You can expect sequential read speeds up to 5000MB/s and sequential write speeds up to 4800MB/s.
Is this SSD suitable for laptops?
Yes, its M.2 2280 form factor and slim heatsink are designed to fit into diversified desktops, mini PCs, and laptops.
Does it have DRAM?
No, this SSD is DRAM-less and uses Host Memory Buffer (HMB) technology instead.
Are there known issues with this drive?
Some users have reported issues with the controller being buggy, the drive running hot, and premature failures leading to read-only states.
Buying Guide
When buying an SSD, you're looking for a balance of speed, capacity, and reliability. For NVMe drives, the PCIe generation (Gen4 here) dictates the theoretical maximum speed. However, the controller and whether it has DRAM cache significantly impact how consistently those speeds are maintained, especially under heavy load. A heatsink helps manage heat, which is crucial for preventing performance drops.
PCIe Gen4x4
This refers to the interface standard. Gen4 is faster than Gen3, allowing for higher theoretical read/write speeds, like a wider highway for your data. The 'x4' means it uses four lanes of that highway.
M.2 2280
This is the physical size and shape of the SSD. M.2 is a small form factor, and '2280' means it's 22mm wide and 80mm long, which is the most common size for laptops and desktops.
DRAM-less
DRAM acts as a fast buffer for the SSD's mapping table, like an index in a book. Without it, the SSD uses a portion of your system's RAM (Host Memory Buffer), which is slower and can impact sustained performance, especially with many small files.
Alternatives
If this drive doesn't fit your needs, look for PCIe Gen4 NVMe SSDs with dedicated DRAM cache, higher endurance ratings (TBW), and controllers from reputable manufacturers known for stability and sustained performance.
