NVMe Gen4 is a solid-state drive that uses the NVMe protocol over a PCIe 4.0 interface. In practice, that means up to around 7,000 MB/s sequential read speeds – roughly double NVMe Gen3 and many times faster than a SATA SSD. For a modern gaming PC, that extra speed doesn’t just shave a few seconds off boot time; it helps keep worlds loading smoothly, textures streaming cleanly, and your system feeling instantly responsive.
What Is NVMe Gen4?
When people say “NVMe Gen4”, they usually mean an M.2 NVMe SSD installed in a motherboard slot that supports PCIe 4.0. The drive talks directly to the CPU over PCIe lanes instead of the older SATA pathway, removing a key bandwidth bottleneck.
Typical ballpark numbers:
- SATA SSD: ~550 MB/s
- NVMe Gen3: ~3,500 MB/s
- NVMe Gen4: ~7,000 MB/s
That’s why Gen4 has become the default choice in many current gaming PCs based on AMD Ryzen 5000/7000 and Intel 12th–14th Gen platforms.
How NVMe Gen4 Affects Gaming
Storage speed rarely increases raw FPS the way CPU or GPU upgrades do, but it does affect how those frames are delivered. NVMe Gen4 helps with:
- Faster game and level load times
- Quicker reloads after deaths or fast travel
- Smoother texture and asset streaming in large open worlds
- Faster installs and patches for 100–200GB AAA titles
In games that constantly stream data – open‑world RPGs, flight simulators, racing titles – a Gen4 drive reduces the chance of texture pop‑in or brief hitches when the engine needs to pull a lot from disk at once. That’s why you’ll often see Gen4 included by default in well-balanced gaming PCs under $2,000 and higher‑tier performance PCs under $3,000.
Gen4 vs Gen3 vs Gen5
Gen3 NVMe is still perfectly capable for gaming, especially if you’re coming from a hard drive or first‑generation SATA SSD. The biggest step change is HDD → SSD; after that, gains are more about consistency and workload headroom.
Gen4 NVMe sits in the sweet spot:
- Noticeably faster than Gen3 for large files and heavy multitasking
- Widely supported on modern AMD and Intel platforms
- Reasonable price, especially at 1–2TB capacities
Gen5 NVMe pushes speeds even further on paper, but:
- costs more,
- usually runs hotter,
- and offers relatively small benefits for gaming workloads alone.
For most players putting together a serious rig – whether it’s an AMD Ryzen 7 gaming PC, an Intel i7 gaming PC, or a balanced NVIDIA RTX gaming PC – Gen4 is the sensible default.
How Much NVMe Gen4 Storage Do You Need?
Modern titles are huge. A single premium release can exceed 150–200GB after patches and texture packs. Practical targets:
- 1TB Gen4 – solid baseline for a few big games plus the OS
- 2TB Gen4 – ideal for a rotating library, mods, and recordings
- 4TB+ Gen4 – for large collections or combined gaming + content creation
A common strategy is a 1TB or 2TB Gen4 drive as your primary game/OS drive, with optional secondary storage for overflow. If you’re configuring a rig in the Build Custom PC tool, locking in Gen4 as your main drive is one of the easiest quality‑of‑life upgrades you can make.
Who Should Prioritize NVMe Gen4?
NVMe Gen4 is especially worthwhile if:
- You’re buying a new system on a current‑gen platform
- You play open‑world, simulation, racing, or 4K titles
- You want a PC that feels fast in everyday use, not just in benchmarks
- You stream or run background apps while gaming
In short: if you’re already investing in a modern mid‑range or high‑end GPU and CPU, NVMe Gen4 is the storage tier that keeps the rest of the build from feeling old before its time.
