AI Verdict
This 1TB NVMe Gen3 QLC SSD with up to 3,200 MB/s read speed is for revitalizing older systems or as a secondary drive for everyday tasks.
This 1TB NVMe Gen3 SSD is a situational fit because its 3,200 MB/s read speed offers a noticeable boost over SATA drives for daily tasks and OS loading. However, its QLC NAND, DRAM-less design, and 100 TBW endurance rating mean it's not built for heavy, sustained write operations or high-performance applications.
If you need better sustained write performance and higher endurance, look for NVMe SSDs with TLC NAND and a dedicated DRAM cache.

Pros
- Achieves sequential read speeds up to 3,200 MB/s, significantly faster than SATA drives.
- Features a slim M.2 2280 form factor, fitting easily into compatible laptops and desktops.
- Offers 1000 GB capacity, providing ample storage for an operating system and applications.
- Designed with shock-resistance, protecting data against accidental bumps and drops due to no moving parts.
- Includes downloadable Western Digital SSD Dashboard for monitoring drive health and usage.
- Backed by a 3-year limited warranty.
Cons
- Utilizes QLC NAND, which typically has lower endurance and can see performance drops compared to TLC NAND.
- Lacks a DRAM cache, relying on Host Memory Buffer (HMB) which can impact sustained write performance.
- Rated for a low endurance of 100 TBW for the 1TB model, significantly below the 500-600 TBW common for similar capacity NVMe SSDs.
- Experiences substantial write speed degradation, dropping to around 100 MB/s after its SLC cache is exhausted during large file transfers.
- Operates on PCIe Gen3, not the faster Gen4 or Gen5 interfaces available in newer drives.
Dimension Scores
The drive offers up to 3,200 MB/s sequential read, which is competitive for a Gen3 PCIe drive, but write speeds drop significantly after the SLC cache fills.
The 1TB model's 100 TBW endurance rating is considerably lower than the 500-600 TBW common for 1TB NVMe SSDs, and it comes with a 3-year warranty instead of the typical 5 years for higher-tier drives.
1000 GB is a practical capacity for an operating system, essential applications, and a reasonable amount of data storage for most users.
The M.2 2280 form factor and NVMe interface are widely supported in modern laptops and desktops, making it compatible with many systems.
Best For
- Revitalizing older laptops or desktops equipped with an NVMe M.2 slot.
- As a boot drive for budget PC builds focused on basic daily computing.
- Secondary storage for less demanding games or general file storage.
- Users needing a cost-effective upgrade from a traditional hard drive or SATA SSD.
Not Recommended For
- High-performance gaming systems requiring minimal load times for large titles.
- Workstations involved in professional video editing or frequent large file transfers.
- Users requiring sustained high write speeds for intensive data operations.
- Systems without an M.2 NVMe slot.
Watch Out For
- The 1TB model uses QLC NAND, which has a lower write endurance of 100 TBW, making it less suitable for heavy write workloads.
- Write speeds can plummet to approximately 100 MB/s once the SLC cache is full, impacting performance during large data transfers.
- This drive is DRAM-less, relying on 64 MB of Host Memory Buffer, which can lead to slower performance under sustained loads compared to drives with dedicated DRAM.

What Buyers Say
Many users upgrading from older hard drives or SATA SSDs report a noticeable speed increase for everyday tasks and boot times. However, the drive's performance can hit a wall during large file transfers, with write speeds dropping dramatically once the small SLC cache is exhausted. The QLC NAND and lower endurance rating are frequently mentioned as trade-offs for its budget-friendly price point, making it a better fit for lighter use cases rather than demanding workloads.
“Dude, I just needed something to make my old laptop not feel like a dinosaur, and this totally did it for opening Chrome and my docs, but don't even think about moving my whole Steam library at once, it chokes hard.”
Common Praise
- Operating system boots up much faster than with a hard drive or SATA SSD.
- Applications load quickly, improving daily computing responsiveness.
- Installation is straightforward in systems with an M.2 NVMe slot.
- Runs cool, even when installed in laptops with less airflow.
- Provides a significant performance boost for older computers.
Common Complaints
- Write speeds become very slow, around 100 MB/s, when transferring large files after the cache is full.
- The 100 TBW endurance rating is low, raising concerns for long-term heavy use.
- It's a DRAM-less drive, which can affect sustained performance.
- Not suitable for high-performance tasks like intensive gaming or professional content creation.
Ownership Tips
- The performance difference is most apparent in boot times and opening common applications, not necessarily in heavy file operations.
- Monitoring the drive's health with the WD SSD Dashboard is a good idea, especially given the QLC NAND and lower TBW.
- For a secondary drive where large, continuous writes are rare, the speed drop isn't a constant issue.
- It's a silent upgrade, as there are no moving parts to generate noise.
Frequently Asked Questions
Is this SSD compatible with my PlayStation 5?
No, the WD Green SN350 is a PCIe Gen3 drive, and the PlayStation 5 requires a PCIe Gen4 NVMe SSD for compatibility and optimal performance.
Does this SSD come with a mounting screw?
Some users have reported that it does not include a mounting screw, so you might need to source one separately or use the one provided by your motherboard or laptop.
What is QLC NAND and why does it matter?
QLC (Quad-Level Cell) NAND stores four bits of data per cell, allowing for higher capacity at a lower cost. However, it generally results in lower endurance and slower write speeds, especially after the drive's cache is full, compared to TLC (Triple-Level Cell) or MLC (Multi-Level Cell) NAND.
Will this SSD make my computer significantly faster?
If you are upgrading from a traditional hard drive or a SATA SSD, you will likely experience a significant speed improvement for boot times, application loading, and general responsiveness due to its 3,200 MB/s read speed.
Does this drive run hot?
Some users have reported that the WD Green SN350 runs relatively cool, even in laptops, making it suitable for systems with limited cooling.
Buying Guide
When you're looking at an SSD like this, you need to understand that not all NVMe drives are built the same. This one uses PCIe Gen3, which is fast, but not the absolute fastest available today. The 'QLC' part means it's designed for affordability and capacity, but it trades off some endurance and sustained write speed. If you're just browsing, doing office work, or light gaming, you probably won't notice the compromises. But if you're constantly moving huge files around, you'll feel it.
NVMe Interface
This is how the SSD talks to your computer. NVMe is much faster than the older SATA interface, allowing for quicker boot times and application loading, like upgrading from a slow country road to a highway.
M.2 2280 Form Factor
This describes the physical size and shape of the SSD. M.2 2280 is a small, stick-like form factor that plugs directly into your motherboard, saving space and simplifying cable management compared to traditional 2.5-inch drives. Think of it like a slim USB stick for your computer's insides.
QLC (Quad-Level Cell) NAND
This refers to the type of memory cells used to store data. QLC stores more data per cell, which makes the drive cheaper per gigabyte, but it generally means the drive has lower endurance (how much data can be written over its lifetime) and can be slower for sustained writes once its small, faster cache is full. It's like having a bigger, cheaper storage locker, but it takes a bit longer to put things in if you're filling it up all at once.
Up to 3,200 MB/s Read Speed
This number tells you how fast the drive can pull data off the disk. A higher number means your operating system, games, and applications will load much quicker. For comparison, a traditional hard drive might only hit 150 MB/s, and a SATA SSD around 550 MB/s, so 3,200 MB/s is a significant jump for getting things started.
Alternatives
If this drive doesn't quite cut it, look for NVMe SSDs with PCIe Gen4 or Gen5 interfaces, TLC NAND, and a dedicated DRAM cache for better sustained performance and higher endurance ratings.
