The WD_BLACK SN850X remains the gold standard for PCIe 4.0 drives, and frankly, it makes spending more money feel entirely unnecessary. In my daily workflow, which involves constant video assets and large game libraries, the SN850X never faltered. It hits nearly the theoretical limit of the Gen4 interface, and unlike some competitors, it maintains high speed even when the drive starts to fill up. You’re getting a top-tier controller with a dedicated DRAM cache, which is vital for the responsiveness that cheap, DRAM-less drives simply cannot replicate. While some newer PCIe 5.0 drives are creeping into the market, they are significantly more expensive and run much hotter; the SN850X provides the perfect balance of cool operation and blistering speed. The only minor limitation is that the software suite can be a bit heavy for users who just want a “plug and play” experience, but the raw drive performance is so strong that I can easily overlook this. It is the most reliable, high-performing drive for any gamer or creative professional who wants to maximize their current platform without breaking the bank.

| Endurance | 1500 TBW |
The Lexar NM790 is a fascinating drive because it proves you don’t necessarily need a physical DRAM cache to achieve competitive speeds. By using Host Memory Buffer (HMB) technology, the NM790 leverages a portion of your system RAM to handle mapping, which keeps costs low while keeping performance impressively high. In my testing, I found it to be exceptionally snappy for loading games and booting Windows. It feels just as fast as the more expensive drives in day-to-day use, and the write endurance is actually higher than most drives in this price range. You are definitely saving money here, but you’re only sacrificing the dedicated hardware cache, which most gamers will never miss in a real-world scenario. It is the perfect choice for someone building a secondary PC or looking to upgrade a console where you want maximum capacity for your dollar. It’s not the absolute fastest drive for massive, sustained 4K video editing, but for everything else, it is a stellar value that forces you to rethink why you’d pay more for a “brand name” drive. I highly recommend this for anyone wanting to maximize their storage capacity without feeling the sting in their wallet.
- Incredibly low price-to-capacity ratio
- Extremely high endurance rating
- Very fast game load times
- Lacks dedicated physical DRAM

The Samsung 990 PRO is the drive I personally trust for my most critical data. While it sits closer to the top of our budget limit, the “stretch” is entirely justified by the reliability of the Samsung controller and the maturity of their Magician software. In my testing, this drive consistently delivers the most stable, predictable performance across every benchmark I threw at it. If you are someone who works in professional video production or heavy data-set analysis, you don’t want to worry about your drive controller hitting a bottleneck or overheating during a render. Samsung’s proprietary controller is simply in a league of its own. Yes, you pay a premium for the brand and the engineering, but that extra investment buys you a peace of mind that is worth it for anyone who makes money with their computer. It’s an incredibly polished product that feels premium from the moment you hold the packaging to the moment you install it. While the SN850X provides more value for the average gamer, the 990 PRO is the ultimate choice for those who want the absolute pinnacle of Gen4 performance and software support.

Frequently Asked Questions
Is the DRAM-less Lexar NM790 really as good as a DRAM-equipped drive?
For gaming and general use, yes. The Lexar NM790 uses HMB technology, which is incredibly mature now. While a drive with physical DRAM like the WD_BLACK SN850X is theoretically better for sustained workstation tasks like 4K video editing, you would be hard-pressed to notice a difference in game loading times or daily office productivity. If your budget is tight, the NM790 is a fantastic choice that doesn’t feel compromised.
Should I buy a new drive or look for used ones at this price point?
Avoid used SSDs at all costs. SSDs have a finite lifespan measured in Terabytes Written (TBW). When you buy used, you have no way of knowing if the previous owner exhausted 90% of the drive’s health. Given how affordable top-tier 2TB drives are today, the small savings from buying used aren’t worth the risk of sudden data loss. Stick to new units with full factory warranties.
Can I use these Gen4 drives in a PS5?
Yes, all five of these drives are compatible with the PlayStation 5. However, ensure you purchase the version that includes a heatsink, or install an inexpensive aftermarket one. The PS5 is very sensitive to thermal throttling, and a naked drive in an enclosed console slot can lead to system-wide performance degradation during long gaming sessions.
What is the biggest mistake people make when buying SSDs under $300?
The most common mistake is buying a 4TB drive that is “on sale” but uses QLC NAND. QLC is significantly slower and has lower endurance than the TLC NAND found in the 2TB drives listed here. For a primary boot drive or a high-performance gaming drive, stick to TLC NAND. You are much better off with a reliable 2TB TLC drive than a slow, cheap 4TB QLC drive that will struggle to maintain speeds.
When is the best time to find the lowest prices on these drives?
SSD prices fluctuate heavily based on NAND supply cycles. However, you will almost always find the best deals during major retailer events like Prime Day or Black Friday. If you aren’t in a rush, use a price-tracking browser extension to monitor these specific models; they frequently dip by 10-15% during off-peak times as retailers cycle their inventory. Never pay MSRP, as these drives are almost always on some form of promotional discount.
Final Verdict
If you need the most reliable, all-around performer, the WD_BLACK SN850X is the clear winner for most users. If your budget is tight and you want the absolute most storage for your money, the Lexar NM790 remains undefeated. For those who can stretch slightly for professional-grade stability and industry-leading software support, the Samsung 990 PRO is the premium choice that justifies every extra dollar. The PCIe 4.0 market has reached a point where you really don’t need to spend $300 to get incredible speed and reliability; these five options prove that point perfectly.
