The SSD versus HDD debate has been settled for a few years now, in the sense that SSDs are faster, full stop. But ‘faster’ in the context of gaming is more specific than the broad marketing claims suggest. Understanding what an SSD actually changes, and what it does not, will help you decide whether the upgrade is worth it for your situation.

What an SSD changes in gaming

Load times

This is the most obvious and measurable difference. Games that took 60-90 seconds to load from a hard drive load in 5-15 seconds on a modern NVMe SSD. The difference is dramatic, and it is permanent: every time you load a level, respawn in an open world, or start a session, you save that time.

On conventional HDDs, you also get the occasional stutter mid-game as large assets are streamed from disk. In games with dense open worlds, this manifests as texture pop-in or brief freezes as you move quickly through environments. SSDs largely eliminate this.

Open-world game performance

This is where the SSD advantage becomes meaningful beyond mere convenience. Games like Cyberpunk 2077, Horizon Forbidden West, and Microsoft Flight Simulator stream enormous amounts of data from storage as you move through the world. On a hard drive, the data pipeline cannot keep pace with how fast you move through environments, and the result is visible: compressed or missing textures, delayed asset loads, and in some cases frame hitches.

On an SSD, that streaming bottleneck is removed. You still need the GPU and CPU to maintain frame rates, but at least the storage is not the weak link.

Does an SSD improve frame rates?

Directly, almost never. Frame rate is determined by your GPU and CPU, not your storage. Moving a game from HDD to SSD will not change your average fps in a benchmark.

What it can change is frame time consistency, which is the less discussed but arguably more important metric. A game running at 60fps with occasional storage-induced hitches is a worse experience than one running at a steady 60fps. SSDs largely eliminate that category of stutter.

NVMe vs SATA SSD: does the type matter for gaming?

NVMe SSDs (the M.2 format that plugs directly into your motherboard) are significantly faster than SATA SSDs in sequential read/write speeds. A budget NVMe drive reads at around 3,000 MB/s; a high-end one at 7,000 MB/s. SATA SSDs top out around 550 MB/s.

For gaming specifically, this difference matters less than the raw numbers imply. Game load times are not exclusively limited by sequential read speed; they involve many small file reads, which are closer in performance between SATA and NVMe than the headline numbers suggest.

In practice, a SATA SSD will load most games only marginally slower than an NVMe drive. The difference between a good SATA SSD and a budget NVMe is often under a second on most loads. Both are vastly faster than any HDD.

The exception is the very fastest PCIe Gen 5 NVMe drives, which pair with consoles designed around fast storage (the PS5’s custom SSD architecture, for example) and game engines built to leverage it. For PC gaming in general, though, mid-range NVMe is the sweet spot.

Is an HDD still usable for gaming?

Technically yes. Many games still run on HDDs. However:

  • Load times are substantially longer
  • Open-world games with aggressive asset streaming perform noticeably worse
  • Some newer titles have begun listing SSD as a minimum requirement, not just recommended

If budget is a constraint, running your operating system and most-played games on an SSD while using an HDD for large game libraries (older titles, games you play occasionally) is a sensible approach. The HDD becomes archive storage, not your primary gaming drive.

The upgrade case

An 1TB NVMe SSD costs under £70 from reputable brands. A 2TB option is typically under £120. These are not significant investments in the context of a gaming PC, and the quality-of-life improvement is immediate and real.

If you are still running games from a mechanical hard drive, this is the single highest value-per-pound upgrade available to most PC gamers. It will not change your frame rates, but it will meaningfully change how your system feels to use every single session.

What to look for when buying

  • Capacity: 1TB is the practical minimum for a primary gaming drive. Modern games are large; 100GB single titles are increasingly common
  • Interface: NVMe (M.2) if your motherboard has an available M.2 slot (most do since around 2017)
  • Brand: Samsung, Crucial, Western Digital, Seagate, Kingston, and Lexar all produce reliable drives. Avoid obscure no-name brands from marketplace sellers
  • TBW (Terabytes Written): This is the endurance rating. For gaming, a standard consumer drive is fine; you are reading far more than you write

The verdict

An SSD matters for gaming in the ways that affect your daily experience most: load times, open-world streaming, and eliminating storage-induced hitches. It does not improve GPU-driven frame rates.

For anyone still gaming from a hard drive, upgrading to an NVMe SSD is the most impactful low-cost upgrade available. The choice between SATA and NVMe is less important for gaming than marketing suggests; either is a significant improvement over spinning rust. The choice between a cheap and a mid-range NVMe matters even less.

Buy the storage. Load faster. Move on to the actual game.
