Why Upgrade to NVMe?
Switching from a traditional hard drive or even a SATA SSD to an NVMe drive like the WD Green SN350 transforms your laptop's responsiveness. Boot times drop to under 10 seconds, applications launch instantly, and large files transfer in a fraction of the time. For students and professionals in Lahore, Karachi, Islamabad, Rawalpindi, Faisalabad, Multan, Peshawar, or Sialkot, this upgrade is one of the most cost-effective ways to speed up an older laptop. Whether you're editing documents, browsing the web, or running light creative software, the SN350 eliminates the waiting.
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 5530, Latitude 5430, XPS 15 9520, Precision 7550, and also Lenovo ThinkPad T14, HP EliteBook 840 G8, and ASUS ZenBook 14. 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.
This drive is especially popular among customers looking to give a second life to older business laptops like the Dell Latitude 5480 or HP ProBook 450 G5. A quick NVMe swap makes these machines feel modern again, ideal for everyday tasks and remote work.
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 Green SN350 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.
For everyday use — opening multiple Office apps, editing photos in Lightroom, or even light video editing — this drive provides a noticeable boost over SATA SSDs. It's also a great match for basic gaming: game load times are cut in half compared to a hard drive, though for heavy AAA titles you might prefer a higher-end WD Blue or Black series.
Thermals
Like any high-end NVMe drive, the Green SN350 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. The drive also sips power, making it a good choice for battery-conscious users.
How to install in your laptop
Installation is straightforward and takes about 10 minutes:
- Power down the laptop and remove the bottom cover (usually 8-12 Phillips screws).
- Locate the M.2 2280 slot — it's a long narrow connector with a single mounting screw at the far end.
- Insert the SSD at a 30° angle, then press it flat and secure with the mounting screw.
- Reassemble and boot. Use Samsung Data Migration / Acronis True Image / Macrium Reflect to clone your existing drive, or install Windows fresh from a USB stick.

Frequently asked questions
Can I install this in Acer Aspire 5?
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 80 TBW matter for me?
TBW means "terabytes written" — the total amount of data you can write to the drive before the warranty ends. 80 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.
How does the WD Green SN350 compare to the WD Blue SN570?
The Blue SN570 is faster (up to 3500 MB/s read) and has higher endurance, but the Green SN350 is more affordable and perfectly adequate for everyday computing. If you're building a budget system or upgrading an older laptop, the SN350 gives you the NVMe experience without the premium price. For heavy workloads like 4K video editing or large database work, the Blue series would be a better fit.
