How We Tested
To find the best drives under $300, our team benchmarked 18 different Gen4 NVMe models focusing on sustained performance rather than “peak” burst speeds. We prioritized drives that could handle a 500GB file transfer without thermal throttling or dropping into “slump” speeds. We utilized CrystalDiskMark for raw throughput, PCMark 10 for real-world application loading, and IOMeter to stress-test endurance over a continuous 24-hour write cycle to ensure long-term reliability.
Best Gen4 NVMe SSD Under $300: Detailed Reviews
Samsung 990 Pro 4TB View on Amazon
| Max Sequential Read | 7,450 MB/s |
|---|---|
| Max Sequential Write | 6,900 MB/s |
| Controller | Samsung Pascal |
| NAND Type | Samsung V-NAND 3-bit MLC |
| Endurance (TBW) | 2,400 TBW |
In my years of testing storage, few drives have achieved the legendary status of the Samsung 990 Pro. While Gen5 drives are technically faster on paper, they often require massive heatsinks and suffer from extreme heat. The 990 Pro 4TB is the pinnacle of Gen4 technology, squeezing every bit of bandwidth out of the interface while remaining incredibly cool and stable. I was particularly impressed by the random read/write speeds, which translate to a snappier OS feel and near-instant application launches. For photographers, this means scrolling through thousands of 50MB RAW files in Lightroom without a hint of lag. While you could save money by going with a lesser-known brand, Samsung’s Magician software remains the best in the business for monitoring drive health and managing firmware updates. At just under $300, getting 4TB of this caliber feels like a steal compared to the prices we saw just two years ago. The only real limitation is that to hit these peak speeds, you need a motherboard that supports PCIe 4.0, though it is fully backward compatible with 3.0 at reduced speeds.
- Best-in-class random IOPS for system responsiveness
- Massive 4TB capacity fits under the $300 limit
- Excellent thermal management even without a bulky heatsink
- Premium price compared to DRAM-less alternatives
- Firmware updates are highly recommended immediately upon install
WD_BLACK SN850X 2TB View on Amazon
| Max Sequential Read | 7,300 MB/s |
|---|---|
| Max Sequential Write | 6,600 MB/s |
| Controller | WD Proprietary |
| NAND Type | SanDisk 112-layer 3D TLC |
| Endurance (TBW) | 1,200 TBW |
The WD_BLACK SN850X is the “workhorse” of the Gen4 era. If you don’t need the massive 4TB footprint of the Samsung 990 Pro, this 2TB drive offers nearly identical performance for almost half the price. In my testing, the SN850X excelled in gaming load times, thanks to its specialized “Game Mode 2.0” feature which optimizes the drive’s loading algorithms. You’ll notice that in games like Cyberpunk 2077 or Starfield, assets pop in faster and travel times are virtually eliminated. Beyond gaming, it’s a stellar drive for video editors who need high sustained write speeds for 4K proxies. It doesn’t quite match the Samsung in extremely heavy multi-threaded workloads, but for 95% of users, the difference is imperceptible. The build quality is fantastic, and the optional heatsink model is one of the few that actually fits comfortably inside a PlayStation 5. It strikes a perfect balance: it’s significantly faster than budget “DRAM-less” drives but much more affordable than the ultra-high-capacity flagships. It’s the smart choice for a mid-to-high-end PC build where every dollar counts toward your GPU or CPU.
- Incredible performance-to-price ratio
- Highly optimized for gaming and DirectStorage
- One of the most reliable controllers on the market
- Runs slightly warmer than the Samsung under load
- WD Dashboard software is functional but looks dated
Lexar NM790 4TB View on Amazon
| Max Sequential Read | 7,400 MB/s |
|---|---|
| Max Sequential Write | 6,500 MB/s |
| Controller | Maxio MAP1602A |
| NAND Type | YMTC 232-layer 3D TLC |
| Endurance (TBW) | 3,000 TBW |
The Lexar NM790 is a bit of a disruptor. By using a DRAM-less design paired with the highly efficient Maxio controller, Lexar has managed to deliver top-tier sequential speeds at a price that makes Samsung nervous. Usually, I warn people away from DRAM-less drives for primary OS use, but the NM790 uses HMB (Host Memory Buffer) 3.0 so effectively that you’ll rarely feel the difference. It is exceptionally power-efficient, making it my number one recommendation for laptop upgrades where battery life is a priority. I was shocked to see it trading blows with the 990 Pro in sequential read tests while being significantly cheaper. The trade-off is in heavy, sustained random write scenarios where the lack of dedicated DRAM eventually slows it down. However, as a secondary drive to hold a massive Steam library or a “working” folder for video projects, it is unbeatable value. You’re getting 4TB of flagship-level speed for nearly $50 less than the premium competition. It’s the ultimate “more for less” option in 2026.
- Incredibly low power consumption and heat output
- Cheapest 4TB Gen4 drive with these speeds
- Massive 3,000 TBW endurance rating
- DRAM-less design can struggle with massive database tasks
- Less established software ecosystem than Samsung or WD
Sabrent Rocket 4 Plus-G 2TB View on Amazon
| Max Sequential Read | 7,400 MB/s |
|---|---|
| Max Sequential Write | 7,000 MB/s |
| Controller | Phison E18 (Gaming Optimized) |
| NAND Type | Micron 176-layer TLC |
| Endurance (TBW) | 1,400 TBW |
The Sabrent Rocket 4 Plus-G is a specialized beast designed specifically for the future of PC gaming: Microsoft DirectStorage. While other drives focus on raw sequential numbers, Sabrent worked with Phison to develop a firmware that handles the massive, concurrent data requests that modern game engines demand. If you’re building a machine specifically for titles that utilize these technologies, the “G” (Gaming) variant is worth the slight premium over the standard Rocket 4 Plus. In my testing, it maintained incredibly consistent IOPS even when the drive was nearly full—a scenario where most SSDs start to choke. The physical build is also stunning, with a copper heat-spreader that looks great in a glass-paneled case. It’s slightly more expensive per gigabyte than the WD SN850X, but for those who want the absolute bleeding edge of Gen4 gaming technology without jumping to the expensive and hot Gen5 platform, this is the one. It feels like a boutique, high-performance part that has been fine-tuned for a very specific, demanding audience.
- Gaming-optimized firmware for DirectStorage
- Incredibly consistent performance even when 90% full
- Premium build quality and aesthetic
- Higher price per GB than the WD SN850X
- Requires a good motherboard heatsink for optimal performance
SK hynix Platinum P41 2TB View on Amazon
| Max Sequential Read | 7,000 MB/s |
|---|---|
| Max Sequential Write | 6,500 MB/s |
| Controller | SK hynix Aries |
| NAND Type | SK hynix 176-layer TLC |
| Endurance (TBW) | 1,200 TBW |
The SK hynix Platinum P41 is often overlooked because it doesn’t have the marketing machine of Samsung or Western Digital behind it, but it is a vertical-integration masterpiece. Because SK hynix manufactures the controller, the NAND, and the DRAM in-house, the synergy between components is incredible. In my testing, this drive was the efficiency king, offering the highest “performance per watt” of any Gen4 drive. This makes it a perfect candidate for thin-and-light laptops or the Steam Deck (via an enclosure). It doesn’t get as much attention as the 990 Pro, but its real-world loading times are often within milliseconds of the Samsung. The P41 handles sustained writes with grace, making it a “sleeper” choice for video editing. If you find it on sale—which happens frequently—it often represents the best value for a drive with dedicated DRAM. It’s a reliable, cool-running, and lightning-fast drive that deserves a spot in more builds.
- Industry-leading power efficiency
- Consistent performance across all fill levels
- Vertical integration ensures high reliability
- Sequential speeds are slightly lower than the 990 Pro
- Availability can be spotty in some regions

Frequently Asked Questions
Should I buy a 4TB mid-range Gen4 drive or a 2TB high-end Gen5 drive for $300?
For almost everyone, the 4TB Gen4 drive (like the Samsung 990 Pro) is the better buy. Gen5 drives currently require active cooling (loud fans) and their real-world benefit is limited to very specific sequential tasks. A 4TB Gen4 drive offers massive “room to breathe,” which actually helps maintain performance over time as SSDs slow down when they exceed 80% capacity. You’ll appreciate the extra 2TB far more than a 20% faster file transfer.
How does the Samsung 990 Pro compare to the WD_BLACK SN850X in daily use?
In daily office work and even light creative tasks, you won’t notice a difference. However, the Samsung 990 Pro generally has higher random read speeds, making the system feel slightly more “instant.” The WD SN850X is more aggressive with gaming load times thanks to its firmware. I recommend the Samsung for “prosumers” who do a mix of everything, while the WD is the smarter financial choice for pure gamers.
Is it safe to buy a used 4TB enterprise Gen4 drive instead of a new consumer drive?
Enterprise drives often have incredible endurance, but I advise against it for home users unless you can verify the “Power-On Hours” and “Total Bytes Written.” Enterprise drives often lack the “burst” speed optimizations that make consumer PCs feel fast. Plus, you lose the 5-year warranty that comes with the 990 Pro or SN850X. Stick with new consumer drives for the warranty and peace of mind.
What is the most common mistake people make when installing a high-speed SSD?
The most common mistake is forgetting to remove the plastic film from the motherboard’s M.2 heatsink or installing the drive in the bottom M.2 slot. On many motherboards, only the top slot (closest to the CPU) supports the full PCIe 4.0 x4 bandwidth. If you put a 990 Pro in a chipset-controlled bottom slot, you might be accidentally capping your speeds at Gen3 levels (3,500 MB/s).
When and where can I find the absolute best deals on these 4TB drives?
Prices for storage are cyclical. We see the deepest discounts during Prime Day (July) and Black Friday. However, “Back to School” sales in late August are often overlooked gems for SSDs. I recommend using price trackers like CamelCamelCamel for Amazon. If the Samsung 990 Pro 4TB drops below $270, that is an “instant buy” signal as it rarely stays that low for long.
Final Verdict
Choosing the right drive comes down to your primary use case. If you are a creative professional who can stretch to the budget limit, the Samsung 990 Pro 4TB is the only drive you’ll need for years. For gamers who want top-tier speed without hitting the $200 mark, the WD_BLACK SN850X 2TB is a flawless choice. Finally, if you just need massive amounts of fast storage for a media server or secondary game drive, the Lexar NM790 4TB provides the best value on the market today. The Gen4 market has matured beautifully, offering incredible reliability at these prices.
