The PM9A1 OEM is Samsung's own drive for laptop OEMs — it uses the same Elpis controller and 128-layer TLC NAND as the retail Samsung 980 Pro, but comes without retail packaging at a lower price. For most buyers, the real-world difference is zero; you get identical speeds and reliability.
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. It also works great in Lenovo ThinkPad T14, HP EliteBook 840 G7, and ASUS ROG Zephyrus series. If your laptop has only a SATA M.2 slot (no NVMe support), see our laptop parts catalogue at /shop/laptop-parts 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 Gen4 platform the PM9A1 OEM 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.
In real usage, the PM9A1 delivers up to 1,000,000 IOPS random read and 900,000 IOPS random write — numbers that translate to snappy app launches and smooth multitasking even with many programs open.
Thermals
Like any high-end NVMe drive, the PM9A1 OEM 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.
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.
If you'd rather not open your laptop yourself, drop it at our shop and we'll install and clone for Rs. 1,500 (free for purchases above Rs. 20,000). We also stock matching RAM upgrades — see /shop/ram.
Who should buy this drive?
- Gamers who want faster load times in titles like Call of Duty, Cyberpunk 2077, or Valorant.
- Content creators editing 4K or 6K video in Premiere Pro, DaVinci Resolve, or Final Cut.
- Developers running VMs, compiling large projects, or working with Docker containers.
- Everyday users who want a snappier laptop and don't want to wait for files to copy.

Frequently asked questions
Can I install this in MSI GF63 Thin?
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.
