Gen 4 NVMe storage used to be the exclusive territory of flagship builds. The 1TB NVMe SSD (WD Blue SN580 Gen 4) changes that — it's a brand-new Western Digital drive running on PCIe Gen 4 rails, delivering serious sequential throughput at a price point that makes sense for an upgrade rather than a full system rebuild. We stock and ship this drive from Hafeez Center, Gulberg III, Lahore, quality-checked and ready to install.
Performance Numbers
The WD Blue SN580 is built on Western Digital's in-house controller with TLC NAND, tuned for consistent sustained performance rather than just peak burst figures. Sequential read reaches 4,150 MB/s and write hits 4,000 MB/s on the 1TB capacity — figures that compress large project files, load game levels, and transfer video in fractions of the time a SATA drive would take. The 1TB WD Blue SN580 Gen 4 SSD price in Pakistan 2026 is Rs. 49,899 — new and sealed from an authorised source.
