If you need a reliable NVMe upgrade for a Gen 3 laptop and don't want to pay Gen 4 prices, the 512GB NVMe SSD (Lexar NM620 Gen 3) is a clean, well-tested option that hits 3,300 MB/s sequential reads on PCIe Gen 3 x4. It's a brand-new unit, quality-checked at N.N Laptops, Hafeez Center, Gulberg III, Lahore, and priced at a flat Rs. 17,599.
Lexar's NM620 uses an InnoGrit IG5236 controller paired with 3D TLC NAND — a combination that holds up well under sustained workloads. The 512GB capacity is enough for Windows, your primary apps, and a decent project folder, and the drive can be paired with an external HDD or a SATA drive in the optical bay if you need more bulk storage. For students in Lahore, Islamabad, Karachi, or Faisalabad upgrading a 2019-2022 era laptop, this covers the brief well.
