1TB vs 2TB SSD — how much? — Call of Duty alone is now 250 GB.

Modern game install sizes are out of control

Three years ago, a 1TB SSD comfortably held an entire active gaming library. In 2026, a single Call of Duty installation can occupy a quarter of that 1TB on its own.

Current install sizes (verified May 2026):

Five typical AAA games installed simultaneously easily totals 700-900 GB. Add an esports rotation (Valorant + CS2 + League + Apex = ~150 GB) and you're north of 1TB before you've considered Windows or anything else.

Why are games so much bigger now? Three reasons: uncompressed 4K texture packs ship as standard in 2025-2026 titles; high-fidelity audio assets in multiple languages add 10-20 GB per AAA; and shader pre-compilation caches (especially on DirectX 12 / Vulkan) add another 5-15 GB per title after first launch.

Windows + apps — the hidden 100 GB

Before a single game installs, your "1TB drive" already has 80-120 GB consumed by everything that comes before gaming.

Realistic Windows + apps footprint: 100-130 GB on a 1TB drive. On a fresh install with the same apps it's around 80 GB; after a year of use it climbs steadily.

The 1TB math — what actually fits

Starting from 1024 GB advertised capacity:

That 175 GB of free space looks comfortable until you realise:

• Drive slowdown threshold = 85% full. SSDs need 15% spare for the controller's wear-levelling and garbage-collection algorithms. Cross that line and writes slow by 30-60%.
• One large new release (Call of Duty, Baldur's Gate 3, MS Flight Sim) consumes 150-250 GB of that buffer instantly.
• Game updates routinely add 10-30 GB. Major patches across 4-5 active games can chew through 100 GB in a single Patch Tuesday.

In practice, an active gamer on 1TB ends up constantly juggling installed games — uninstalling something to make room for the next thing, then reinstalling weeks later. It's not a hardware problem; it's a friction problem that gets old fast.

On 2TB, the same five AAA games + Windows + apps occupy 830 GB, leaving 1170 GB free — roughly room for five more AAA titles before the 85% rule kicks in. The friction disappears.

Content creator workflows — different math entirely

If you produce video, photography, audio, or 3D content alongside gaming, the storage calculation shifts dramatically.

Video editor (YouTube / TikTok / Twitch VOD):

• 4K raw footage: 60-120 GB per hour shot (depending on codec).
• Premiere Pro / DaVinci Resolve project caches: 50-150 GB per active project.
• Render outputs in multiple formats: 20-50 GB per finished project.
• Active project storage on the working drive: typically 300-700 GB.

Photographer (RAW workflow):

• ~50 MB per RAW file (45 MP modern bodies).
• A typical 1,000-photo wedding shoot = 50 GB.
• Lightroom previews and cache: 20-100 GB.
• Active catalogue with 12 months of recent shoots: 500 GB-1.5 TB.

3D artist / Blender user:

• Per-project asset libraries: 5-50 GB per project.
• Render cache and intermediate files: 20-100 GB per active project.
• Texture libraries (Quixel, Substance Source): 100-500 GB.

A reasonable creator-plus-gamer setup in 2026: 1TB NVMe OS drive + 2TB NVMe active-projects/active-games drive + 4TB external archive. Total active storage 7-8 TB is normal for full-time creators. For a part-time creator, 2TB + external archive often suffices.

Endurance and capacity — they scale together

SSDs have a finite write capacity expressed as TBW (Terabytes Written). Higher-capacity drives have proportionally higher TBW ratings because they have more NAND cells to distribute writes across.

For a typical gamer: daily writes are 5-20 GB (Windows updates, game saves, patches, browser caches). Even a 600 TBW 1TB drive lasts decades at that rate. Endurance is not the limiting factor for gamers.

For a video creator: daily writes can hit 100-300 GB on a working drive. A 1TB drive's 600 TBW rating works out to about 6 years at that pace — within typical drive lifespan, but tightening. A 2TB's 1200+ TBW gives you double the runway.

When 1TB is plenty

1TB still makes sense in five clear scenarios:

Casual gamers — 1-2 active titles at a time. If you've played Hogwarts Legacy for 6 months and now you're moving to Baldur's Gate 3 (uninstalling the previous), 1TB works fine forever.

Office / productivity builds. If gaming isn't the use case, 1TB is more than ample for Office, browsers, business apps and reasonable file storage.

Secondary boot drive on a multi-drive build. A 1TB Gen4 NVMe as the OS drive paired with a larger SATA SSD for games and media is a classic SA-budget configuration.

Older systems being upgraded. A 1TB SATA SSD in an older H110/B250 system transforms boot time and feel. Don't overspend on a 2TB for an aging platform.

HTPC / media centre / SteamOS console builds. A few hundred GB of Plex media or a handful of console-equivalent games doesn't need 2TB.

When 2TB becomes required

Conversely, 2TB is the right pick whenever any of these apply:

Active gamer with 4+ titles installed. Especially if any of them are Call of Duty, Baldur's Gate, MS Flight Sim, or Starfield. The maths above doesn't lie.

Content creator (even part-time). Project files, raw footage, RAW photos and 3D scenes all consume capacity faster than you'll predict.

Game library hoarder. If you're the type who wants to leave 8-10 games installed "just in case I want to play it again," 2TB removes the constant juggling.

Heavy local media library. Plex, Jellyfin, or local-only music/video archives quickly outgrow 1TB.

Future-proofing. If you plan to keep this drive for 5+ years, sizing up at purchase costs much less than upgrading later. The R1,400 spent now is far cheaper than buying a separate drive in year 3.

The hybrid strategy — best of both worlds

For SA builders with a constrained budget but heavy storage needs, the most cost-effective configuration in 2026 is a hybrid NVMe + SATA setup.

Recommended hybrid build:

• 1TB Gen4 NVMe (~R1,650-R2,400) — Windows, essential apps, and 2-3 currently-active AAA games for fastest load times.
• 2TB SATA SSD (~R1,950-R2,400) — Steam library, photo and media archive, secondary games, downloaded content.
• Total: ~R3,500-R4,500 for 3TB combined.

Compare to:

• Single 2TB Gen4 NVMe: R2,950-R3,800 for 2TB total.
• Single 4TB Gen4 NVMe: R6,500-R8,000 for 4TB total.

The hybrid gives you 50% more total capacity than the single 2TB at a marginally higher cost, and you don't sacrifice game load speeds on your active titles. The trade-off: it consumes an M.2 slot plus a SATA port, where the single 2TB NVMe only uses the M.2 slot.

SA price-gap math (May 2026)

Key observation: 2TB Gen4 NVMe is the cheapest tier per-GB in the NVMe range. 2TB SATA is the cheapest overall per-GB. The sweet spots in SA pricing are both at the 2TB capacity point.

The R1,400 gap between 1TB and 2TB Gen4 NVMe is genuinely small considering the practical impact. For comparison, the same R1,400 saved on storage and spent on the CPU would only step you up half a tier (e.g. Ryzen 5 7600X to 7700X). The storage upgrade is far more felt in daily use.

SA picks by use case

Key takeaways

1. 2TB is the new default for active gamers and content creators — game install inflation has changed the math.
2. 1TB is still right for casual gamers, office builds, secondary drives, and older platforms.
3. The R1,400 SA price gap between 1TB and 2TB Gen4 NVMe is the single best per-Rand upgrade in modern builds.
4. Keep at least 15% of any SSD free — drives slow noticeably past 85% capacity.
5. Hybrid setup (1TB NVMe + 2TB SATA) is the smartest budget play for total capacity without sacrificing peak load speed.
