Samsung 990 PRO 1TB Gen4 NVMe SSD — 7450 MB/s Laptop Upgrade
The Samsung 990 PRO 1TB NVMe SSD is a PCIe 4.0 x4 M.2 2280 internal drive built for fast game loading, 4K video editing and heavy multitasking. It delivers up to 7450 MB/s sequential read and 6900 MB/s sequential write, with a 600 TBW endurance rating and a 5-year manufacturer warranty. At N.N Laptops, Shop 66A, 3rd Floor, Hafeez Center, Gulberg III, Lahore, this drive costs Rs. 25,500 with a 30-day check warranty and Lahore delivery.
Why choose the Samsung 990 PRO for your laptop?
If you're building a high-performance laptop or upgrading an existing one, the Samsung 990 PRO is one of the fastest Gen4 NVMe drives you can buy in Pakistan. At Rs. 55,799 (current price, updated 2026), it offers flagship speeds that make everyday tasks feel instant. We at N.N Laptops recommend this drive for users who work with large files—video editors, developers compiling code, or gamers who want the fastest load times in titles like Call of Duty and Cyberpunk 2077. Compared to a Gen3 drive, you get roughly double the sequential throughput, which means copying a 50GB game folder takes under 90 seconds instead of 3 minutes.
Performance you can feel
On a Gen4 platform, the 990 PRO hits up to 7450 MB/s read and 6900 MB/s write sustained. Random 4K performance is equally impressive—this is what makes Windows boot in under 9 seconds and apps open instantly. The drive uses Samsung's proprietary Pascal controller and V-NAND technology, delivering consistent speeds even under heavy loads. It also features a 1GB LPDDR4 DRAM cache, which ensures smooth multitasking when you have dozens of browser tabs open or are running virtual machines. For everyday use—loading Office, browsing, streaming—the drive feels completely silent and cool, running at 55-70°C in most laptops.
Laptop compatibility and installation
This SSD fits any laptop with a standard M.2 2280 NVMe slot, common in most machines built after 2018. We've personally tested it in Dell Latitude 7490, 5490, Inspiron 15 3501, XPS 13 9370, HP EliteBook 840 G6, Lenovo ThinkPad T480, and many more. If your laptop supports PCIe 3.0, the drive will work, but speeds will drop to around 3500 MB/s—still faster than any SATA SSD. Installation is simple: remove the bottom cover, insert the drive at 30°, secure with a screw, and you're done. If you'd rather not do it yourself, drop by our shop at Hafeez Center, Gulberg III, Lahore, and we'll install and clone your old drive for just Rs. 1,500—free for purchases above Rs. 20,000.

Frequently asked questions
Does this work in HP EliteBook 840 G6?
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 Gen4 (PCIe 4.0 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 600 TBW matter for me?
TBW means "terabytes written" — the total amount of data you can write to the drive before the warranty ends. 600 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.
