Patriot Memory P300P2TBM28 2TB M.2 2280 PCIe Gen3 x4 NVMe 1.3 internal SSD

2TB PCIe Gen3 x4 NVMe SSD

The Patriot P300 delivers 2TB of storage in an M.2 2280 form factor for consumer laptops and desktops. It uses a PCIe Gen3 x4 interface with NVMe 1.3 protocol and operates without a DRAM cache, relying on HMB technology. Sequential reads reach up to 2100 MBps and writes up to 1650 MBps.

PCIe Gen3 x4 interface limits

The Gen3 x4 link caps theoretical throughput at roughly 4 GBps, so the drive tops out at 2100 MBps read and 1650 MBps write. Random performance reaches 290,000 IOPS read and 260,000 IOPS write. Power draw sits at 0.38W idle and 2.38W active within a 0 to 70°C range.

Upgrade from hard drives or PCIe 3 x2 SSDs

Replacing a mechanical hard drive cuts boot and load times dramatically thanks to NVMe latency and 320TB endurance. Moving from a PCIe 3 x2 SSD yields about 25% higher transfer speeds and IOPS. The jump is worth it when capacity and sustained throughput matter more than Gen4 peak speeds.
