Laptop compatibility
This drive is a standard M.2 2280 NVMe module, so it fits almost any laptop made in the last five years that has at least one M.2 NVMe slot. We've personally tested it in machines including Dell Latitude 7490, Latitude 5490, Inspiron 15 3501 XPS 13 9370. If your laptop has only a SATA M.2 slot (no NVMe support), see our NVMe and SATA SSDs at /shop/ssd-hdd for the right drive.
How to confirm fit
Open your laptop service manual and look for the phrase "M.2 PCIe NVMe slot — 2280 length". If you see it, this SSD is a drop-in upgrade. If your manual lists "M.2 SATA" only, you need a SATA M.2 SSD instead — WhatsApp 0314 4000131 with your model and we'll confirm before you order.
Real-world performance
On a Gen3 platform the Gold P31 hits its rated speeds during sustained reads of large files — think Windows boot times under 9 seconds, a 50 GB game install in under three minutes, and 4K video scrubbing without dropped frames. Random 4K performance is equally strong, which is what you actually feel when booting Windows, launching apps, and switching between Chrome tabs. The drive uses dynamic SLC caching, so small writes (project files, documents, photos) feel instantaneous.
Thermals
Like any high-end NVMe drive, the Gold P31 can warm up under sustained heavy writes. In a slim laptop with no built-in M.2 heatsink we recommend running HWiNFO and watching temps the first week — most users see 55-70°C under normal load, which is well within Samsung/Kingston/WD spec. For gaming or constant 4K editing, a thin thermal pad between the drive and the bottom cover helps.
Power efficiency and battery life
The Gold P31 is one of the most power-efficient Gen3 SSDs on the market, drawing as little as 2.5W under load and under 0.5W at idle. This translates to longer battery life in your laptop compared to competing drives. In our tests on a Dell XPS 13, swapping from a Samsung PM981 (which pulls up to 5W) to the P31 added roughly 30 minutes of real-world runtime during mixed use. If you're a frequent traveler or work off battery all day, this drive gives you back that extra time.
Why not Gen4?
Gen4 NVMe drives are faster on paper — up to 7000 MB/s — but most laptops still use Gen3 slots. The Gold P31 is optimised for Gen3 laptops and won't throttle or overheat like many Gen4 drives do when plugged into a Gen3 slot. For daily tasks, you simply won't notice the difference between 3500 MB/s and 7000 MB/s; the P31's real-world responsiveness is already excellent. Save your money for other upgrades.
Who is this drive for?
This SSD is ideal for anyone who needs a reliable, fast boot drive for Windows, macOS or Linux. It's a perfect match for:
- Students and office workers — boot up in seconds, open large Excel files instantly, and keep dozens of Chrome tabs snappy.
- Game enthusiasts — load open-world games like Cyberpunk 2077 or GTA V in under 30 seconds.
- Content creators — edit 1080p and 4K video without stuttering; export times drop by half compared to an old SATA SSD.
- System builders — use it as a primary drive in a desktop or a second drive in a laptop for scratch and cache.
If you're upgrading from a traditional hard drive, this is the single biggest performance gain you'll ever make. Thousands of customers at nnlaptops.com have made the switch and seen their laptops feel like new again.

Frequently asked questions
Is this compatible with my Dell XPS 13 9370?
If your laptop has an M.2 2280 NVMe slot (most 2018+ business and gaming laptops), yes. Send us your exact model on WhatsApp 0314 4000131 and we'll confirm before shipment.
Is this Gen3 or Gen4 NVMe?
This drive is Gen3 (PCIe 3.0 x4). It is backwards compatible with older Gen3/Gen2 slots, but you'll only see Gen3 speeds (around 3,500 MB/s) if your laptop's slot is Gen3.
What is TBW and does 750 TBW matter for me?
TBW means "terabytes written" — the total amount of data you can write to the drive before the warranty ends. 750 TBW is enough to write the full capacity of this drive every day for several years, which is far more than typical home or business use.
Will my Windows licence transfer if I clone the old drive?
Yes. Windows 10 and 11 licences are tied to your motherboard, not the SSD. After cloning, Windows will reactivate automatically over the internet.
Do you offer installation in Lahore?
Yes — Rs. 1,500 in-shop install with clone, free for purchases above Rs. 20,000. Walk into Shop 66A, Hafeez Center any time during business hours.
Do you ship to Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot?
Absolutely. We ship nationwide via TCS and Leopards. Freight to all major cities including Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, and Sialkot is via TCS / Leopards. Orders above Rs. 20,000 ship free within Lahore. Simply place your order on nnlaptops.com or WhatsApp 0314 4000131 and we'll arrange delivery.
All drives are bench-tested before shipping to ensure they meet rated speeds and are free from defects. Every new drive comes with a 30-day replacement warranty from N.N Laptops (in addition to the manufacturer warranty). If you need photos of the exact unit, just ask Sayam on WhatsApp — he'll send you live pics and video.
