- Available capacities: 256GB, 512GB, 1TB
Pros: Fits ultrabooks and compact laptops, Gen 4 performance, proven Western Digital reliability, reasonably priced for the form factor.
Cons: Limited to smaller capacities (1TB max), slightly harder to source than standard 2280 drives, niche audience (only certain laptop models).
Best for: Framework laptop owners, ultrabook users, anyone with a space-constrained laptop.
Alternatives: Sabrent Rocket 2230 (£70–90 for 512GB) and Kioxia BG5 (OEM availability varies).
Best SATA SSD: Samsung 870 EVO
If your laptop has an older SATA-only M.2 slot (most laptops made before 2018), NVMe drives won’t fit. The Samsung 870 EVO is the last great SATA SSD still in production. SATA is capped at 550 MB/s, but for older systems, this is still a massive upgrade from a spinning hard drive.
Specs:
- Sequential read: 560 MB/s
- Sequential write: 530 MB/s
- Form factor: 2280 (M.2 SATA)
- DRAM cache: Yes (full)
- Warranty: 5 years, 1,200 TBW (1TB)
- Available capacities: 256GB, 512GB, 1TB, 2TB
Pros: Works in any laptop with M.2 SATA slot, Samsung reliability and warranty, excellent endurance, widely available, mature technology (very stable).
Cons: Much slower than NVMe (SATA protocol limit of 550 MB/s), not upgradeable to NVMe without motherboard/laptop compatibility checking.
Best for: Older laptop upgrades (pre-2018 models). Anyone stuck with a SATA-only system.

Best for Gaming Laptops
Gaming laptops benefit more from large capacity than from top-tier speed. Modern AAA games are 100–200GB each, and storage-constrained gaming laptops become frustrating (constant deletions, slow shader compilation). Choose a 1TB or 2TB drive over a faster 512GB.
Top picks for gaming:
- Crucial T500 2TB — Value and capacity, £150–170. A gamer’s best friend.
- Samsung 990 Pro 2TB — Top speed and capacity, £180–200. For budget-unlimited systems.
- WD Black SN770 1TB — Budget-friendly capacity upgrade, £60–75.
Why capacity matters: Games are stored files, not streamed to VRAM like code. Loading times max out at around 2,500 MB/s (SATA limitation), so 7,100 MB/s NVMe gains you 2–3 seconds per level load. Capacity stops you redownloading games constantly (5–30 minute per-game penalty if storage runs out).
Best for Business Laptops
Business systems prioritise reliability and endurance over pure speed. You’ll be running Office, Slack, Chrome tabs, and video calls — all applications that work perfectly on Gen 3 NVMe. Focus on warranty, TBW rating, and power efficiency.
Top picks for business:
- SK Hynix P41 Platinum — Outstanding endurance (1,200 TBW), 5-year warranty, excellent reliability record.
- WD Black SN770 — Solid Western Digital engineering, good warranty, affordable.
- Crucial T500 — Exceptional endurance (1,200 TBW), proven durability, excellent price.
Why endurance matters: Business laptops accumulate write cycles slowly (email, documents, caching). A 600 TBW drive will last 5–7 years in real-world office use. Enterprise users targeting 10-year lifecycles should choose 1,200+ TBW models.
What to Look For When Buying an SSD
Don’t just chase MB/s numbers. Here are the specs that actually matter:
Capacity: Minimum 256GB (tight but workable), comfortable 512GB (most laptops), recommended 1TB (future-proof), power-user 2TB+.
Form Factor: Standard 2280 fits all modern laptops. Check if you need 2230 (ultrabooks) or 2242 (some older systems). SATA M.2 vs. NVMe — verify your slot type before buying.
DRAM Cache: Look for drives with DRAM cache (full cache, not HMB/host memory). DRAM cache improves sustained write performance and reduces file-copy stalls. Budget drives sometimes use HMB to save cost — acceptable but not ideal.
TBW Endurance Rating: Total Bytes Written. 600 TBW = normal consumer use, 1,200 TBW = heavy workload. Higher is future-proofing. Check the warranty period matches your expected laptop lifetime.
Warranty: Most 2026 flagship drives offer 5 years. Budget drives sometimes 3 years. Longer is better, but realistic — most drives outlast the warranty by years.
Controller & NAND Type: Less important for general buyers (all modern controllers are solid), but look for proven combinations. Samsung’s proprietary controller + Samsung NAND = excellent. SK Hynix’s in-house NAND is outstanding. Western Digital’s controllers are reliable.
Speed Claims: Don’t overbuy. The difference between 4,000 MB/s and 7,100 MB/s is ~2–3 seconds on a large file copy. Real-world laptop tasks feel identical. Prioritise capacity and reliability.
How Much Storage Do You Need?
| Capacity | Real-World Space | Best For | Notes |
|---|---|---|---|
| 256GB | ~180GB usable | Minimal: Office work, email, lightweight coding | Tight. Requires discipline with file management. Avoid if buying new. |
| 512GB | ~380GB usable | Comfortable: General browsing, Office, light media work, light development | Default choice. Works for most users without compromise. |
| 1TB | ~750GB usable | Recommended: Video/photo editing, game installations, large code projects, multi-user systems | Sweet spot. Future-proof for 4–5 years. No file management stress. |
| 2TB | ~1.5TB usable | Power user: Heavy creative work, 50+ games installed, local media library, long-term projects | 2026 prices have made this genuinely affordable (£150–200). |
Rule of thumb: Buy the largest capacity you can afford. Storage never feels excessive, and it simplifies your workflow. OS + critical apps take ~30GB; you want headroom above that.

Frequently Asked Questions
Is NVMe really faster than SATA in real use?
For raw sequential file operations, yes — 7,100 MB/s (NVMe) vs. 550 MB/s (SATA) is a 13× difference. In real-world laptop use (launching Office, browsing, email), the difference feels minimal — maybe 1–2 seconds faster OS boot, imperceptible responsiveness gains. Video/photo editing and game installs show the clearest performance gap. For general productivity, both feel instant.
Can I upgrade my laptop’s SSD myself?
Usually, yes. Most modern laptops have an M.2 slot accessible via a bottom panel. Check your model’s manual or iFixit — typically a 5-minute job with a screwdriver. Older models (MacBooks, some gaming laptops) are soldered and not upgradeable. If unsure, check your laptop manufacturer’s spec sheet before buying.
Should I buy Gen 5 NVMe drives?
Gen 5 drives (up to 14,000 MB/s) exist but are expensive (£250+) and offer no real-world benefit for laptops. Desktop systems with sustained high write workloads benefit more. For laptops, Gen 4 is optimal price-to-performance through 2027.
What’s the difference between endurance ratings?
TBW (Total Bytes Written) is a manufacturer’s estimate of how much data you can write before the drive might fail. A 600 TBW drive rated for 5 years in normal use should outlast your warranty. Real-world endurance often exceeds specs by 2–3×, but the rating gives you confidence for heavy workloads.
Do I need to enable XMP or change BIOS settings?
No. NVMe drives work plug-and-play — no BIOS configuration needed. Your laptop will automatically detect and use the drive at its maximum speed. Just slot it in and let Windows/macOS/Linux recognize it.
What’s the warranty process if my SSD fails?
All major brands (Samsung, Western Digital, SK Hynix, Crucial) offer international 5-year warranties. Contact the manufacturer (not necessarily where you bought it) and they’ll arrange replacement. Keep your proof of purchase. Typical replacement time: 2–4 weeks via mail. This is why buying from reputable retailers matters.
Final Thoughts
The 2026 SSD market is healthy and affordable. You can get a fast, reliable, warranty-backed NVMe drive for under £100. Unless you have a legacy SATA-only laptop, buy NVMe — the speed difference is real and the price premium has vanished. Prioritise capacity and warranty over hitting the highest MB/s numbers.
Our top recommendation remains the Samsung 990 Pro 1TB for most buyers: proven reliability, excellent speed, and a price that reflects the market’s maturity. Budget-conscious buyers should look at the WD Black SN770 512GB or Crucial T500 1TB — both excellent drives at £50–95.
