The Crucial P3 Plus is an exercise in practical, no-frills storage. It uses QLC NAND, which means it isn’t designed to be a high-end boot drive for intensive creative work, but it is phenomenal as a secondary drive in your gaming laptop to house your growing library. During my testing, load times remained very competitive compared to older Gen3 drives, and it stayed impressively cool because of its lower power consumption. The trade-off is in sustained write speeds; if you are constantly downloading and moving 100GB+ files, you will see the speed drop off once the cache fills up. If you are a casual gamer looking to upgrade from a small 512GB stock SSD without spending a fortune, this is the most logical choice. However, power users who frequently move massive raw video files or perform heavy disk-bound tasks should look at higher-end TLC drives instead.
- Extremely affordable for 2TB+ capacities
- Very low power consumption and heat
- Reliable brand support
- Slower write speeds under heavy loads
- Lower endurance rating (TBW) than TLC drives

Frequently Asked Questions
Will a PCIe Gen5 SSD offer better gaming performance in my laptop than a Gen4?
Currently, for gaming, the answer is no. Most modern titles do not saturate the bandwidth of a high-end PCIe Gen4 drive like the 990 Pro. Furthermore, Gen5 drives run significantly hotter, which can be a major disadvantage in a laptop chassis where thermal management is already compromised. You are better off investing in a high-quality Gen4 drive that maintains stable speeds without hitting thermal limits.
Is there a significant difference between the Samsung 990 Pro and the WD_BLACK SN850X?
In synthetic benchmarks, the 990 Pro wins on random I/O performance. However, in real-world gaming scenarios like loading maps or streaming assets, the difference is negligible. I recommend the SN850X if you want to save money for other upgrades, while the 990 Pro is the better choice if you also perform heavy productivity tasks like 4K video rendering alongside your gaming.
Do I need to worry about my laptop’s M.2 slot being single-sided or double-sided?
Yes, this is a common point of frustration. Some ultra-thin gaming laptops have very tight clearance between the motherboard and the bottom panel. Double-sided drives have NAND chips on the back, which can make them too thick to fit. Always check your laptop’s service manual or user forums to see if your slot supports double-sided drives before purchasing a 4TB+ model.
Can I use the Crucial P3 Plus as my primary boot drive?
You certainly can, but it is better suited as a secondary storage drive. Because it uses QLC NAND, its performance can dip if the drive becomes nearly full or if you move massive amounts of data daily. For a boot drive containing your OS and primary applications, a TLC-based drive like the WD_BLACK SN850X provides more consistent speed and longer-term reliability.
Should I wait for holiday sales to buy an SSD?
SSD prices fluctuate based on NAND flash supply cycles. While Black Friday and Prime Day often yield the lowest prices, waiting months for a potential 10% discount is rarely worth the time you spend waiting for slow loading screens today. If you are currently hitting storage bottlenecks, buy the drive that fits your budget now; the utility you gain immediately far outweighs the minor savings later.
Final Verdict
If you want the absolute peak of performance, the Samsung 990 Pro remains king. For gamers looking for the best bang-for-your-buck that won’t compromise load times, the WD_BLACK SN850X is the clear winner. If you are just looking to expand your library on a budget, the Crucial P3 Plus is perfect. For those with thermally constrained ultra-thin laptops, the Solidigm P44 Pro is the premium choice for its incredible efficiency. As NVMe technology continues to mature, we expect even better power management in future drives, but for now, these five represent the best balance of speed and reliability.
