Samsung PM9A1 1TB PCIe 3.0 x4 NVMe M.2
The PCIe 3.0 x4 interface delivers 3500 MB/s reads and 3000 MB/s writes, with 500K random read IOPS, making it a solid performer for everyday tasks. Its 1TB capacity and M.2 2280 form factor fit most laptops and desktops, though it lacks a heatsink for sustained heavy workloads. Best for budget-conscious users upgrading an older laptop or desktop for faster boot times and application loading, not for portable external use.
