There's no doubt that PCIe 5.0 SSDs are the fastest drives on the market right now, with sequential read speeds often exceeding 14,000MB/s, twice what most PCIe 4.0 drives are capable of. For enthusiasts, that seems like a big upgrade on paper, but those theoretical gains don't really translate very well into real-world performance unless you're constantly working with massive files that can actually take advantage of that extra bandwidth.

For a gamer like me, the jump in read and write speeds going from PCIe 4.0 to 5.0 doesn't make the PC feel any faster in day-to-day use. Sure, the numbers look much better when I see people benchmarking the drives in CrystalDiskMark, but game loading times barely improve, Windows boots just as quickly, and overall system responsiveness isn't any better. The reality is that most workloads simply don't push PCIe SSDs hard enough to make a meaningful difference.

Gen 5 SSDs run hotter

I don't want a faster drive at the cost of cooling concerns

I'm already tired of constantly keeping an eye on my CPU and GPU temperatures while gaming. So, the last thing I want in my system is another component that can get hot under heavy load. PCIe 4.0 SSDs already run warmer compared to PCIe 3.0 SSDs, and the new Gen 5 ones can push temperatures even higher. Their increased power draw and faster controllers mean they're harder to keep cool, especially during large file transfers or extended gaming sessions.

I've seen a few PCIe 5.0 SSDs exceeding 70C under heavy workloads while using the motherboard's M.2 heatsink. Sure, you could argue that I could get a model that comes with its own heatsink and maybe even a cooling fan, but that just means more moving parts that could fail down the line and noise that I don't want to deal with. Even if I did take that route, there's no guarantee that it would fit on my motherboard. For instance, my Corsair MP600 wouldn't fit on my Strix X570-E with its heatsink installed, so I had no option but to sacrifice cooling performance and rely on the board's heatsink instead.

They still cost more

It's really not worth paying a premium for diminishing returns

PCIe 5.0 SSDs have been around for quite some time now, but they still demand a premium over PCIe 4.0 counterparts that perform nearly the same in real-world use. Most of the time, you're looking at a price difference of $40-50 for mainstream capacities like 1TB and 2TB, and that difference only gets bigger as you move up the storage tiers. I'd rather save that money and spend it on a better CPU cooler or faster RAM that actually improves gaming performance.

Honestly, the price gap wouldn't be a big deal if the performance jump was noticeable, but that really isn't the case. Outside of benchmarks, most PC users wouldn't be able to tell the difference. I'm not someone who edits RAW 8K videos, transfers terabytes of footage every day, or runs heavy simulations on my PC. So, I simply can't justify paying the extra $50 for a Gen 5 drive when PCIe 4.0 models offer more bandwidth than I'll ever need. In its current state, it feels like many people are just buying them for bragging rights.

Overkill for gaming

What's the point when loading times barely improve?

I wouldn't mind looking past cooling concerns and premium prices if these Gen 5 drives actually made games load noticeably faster, but they don't. Unfortunately, even the fastest PCIe 5.0 SSDs today only shave off a second or two compared to high-end PCIe 4.0 drives in most modern AAA titles—at least from the benchmarks I've seen on YouTube. And once you're in the game, everything feels exactly the same. Even if you're still using a PCIe 3.0 SSD, you don't have to worry about texture pop-ins or asset streaming delays, let alone with a PCIe 4.0 one.

Yes, some games that support Microsoft DirectStorage, like Marvel's Spider-Man 2, Forza Motorsport (2023), and Forspoken, can benefit from a faster SSD, but even then, the improvements are minimal. The feature mainly aims to reduce CPU overhead rather than pushing the SSD's bandwidth to its limits. And when PCIe 4.0 SSDs are already more than adequate for the limited number of games that support DirectStorage, what's the point of rushing to upgrade to a Gen 5 drive for gaming? I can always upgrade when games actually catch up and developers utilize that extra speed.

PCIe 5.0 SSDs are simply ahead of their time

At this point, PCIe 5.0 SSDs feel more like a preview of what's possible rather than something you actually need right now. If you want the bragging rights or you like to future-proof your build for the next several years, I won't stop you from buying one. But for me, paying more for an SSD that runs hotter while performing mostly the same as a Gen 4 drive just doesn't make sense. I'm sure these faster SSDs will have their moment at some point down the line, but we aren't quite there yet. Until software matures enough to benefit from all that impressive bandwidth, I see no reason to upgrade to a PCIe 5.0 SSD. By the time we get there, we might even have PCIe 6.0 SSDs that push the limits even further.
