Patriot P300 256GB NVMe SSD

The Patriot P300 is a 256GB NVMe solid-state drive built for mid-tier storage upgrades. It suits laptop and desktop users who need a reliable boot or secondary drive with low power draw. The drive uses a PCIe Gen 3 x4 interface for broad compatibility with M.2 slots. It is not for buyers who want more storage capacity or higher sequential throughput.

PCIe Gen 3 x4 interface and 256GB capacity

The single specification that decides fit is the PCIe Gen 3 x4 NVMe interface paired with a 256GB capacity. Sequential reads reach up to 1,700MB/s and writes up to 1,100MB/s, while 4K aligned random writes hit 260K IOPs. End-to-end data path protection, SmartECC and thermal throttling protect data integrity. LDPC and NANDXtend ECC extend the NAND flash lifespan.

Straightforward M.2 installation

Installation follows the standard M.2 slot procedure: insert the drive at an angle, press down and secure with the motherboard screw. No cables or drive bays are required. What usually goes wrong is forgetting to enable the NVMe option in the system BIOS or selecting the wrong boot drive during OS setup. Windows 7 through 11 are supported.

Questions about this item

What real-world speed will I see from the 1,700 MB/s read figure once the drive is installed?

Sequential reads reach up to 1,700 MB/s and writes up to 1,100 MB/s on a PCIe Gen 3 x4 link; actual throughput depends on the host controller and workload.

Which interface standard does the drive use and what bandwidth limit does it impose?

The SSD uses an NVMe interface over PCIe Gen 3 x4, capping theoretical bandwidth at roughly 4 GB/s.

What physical slot and keying does the 256 GB module need to fit?

It requires an M.2 M-key slot (2280 form factor) with PCIe electrical connections.
