256 GB PCIe Gen3 x4 NVMe SSD

The Patriot P300 is a 256 GB internal SSD in the M.2 2280 form factor. It uses a PCIe 3.0 x4 interface with NVMe 1.3 for desktops and laptops. The drive has no DRAM cache and relies on HMB technology. End-to-end data path protection guards data integrity.

Sustained workload behaviour

Sequential reads reach up to 1700 MBps and writes up to 1100 MBps. Random performance hits 290,000 IOPS read and 260,000 IOPS write. Active power draw is 2.07 W and idle drops to 0.37 W. The controller operates from 0 °C to 70 °C with thermal management and wear levelling to prevent sharp speed drops over time. Rated endurance is 80 TB written.

Upgrade path from PCIe 3 x2 or SATA

This drive replaces slower PCIe 3 x2 NVMe SSDs or SATA SSDs with a 25 percent gain in transfer speeds and IOPS. The jump is worthwhile when boot times, application launches and file copies feel sluggish on the older interface. Windows 7, 8, 8.1 and 10 are supported, though Windows 7 may need a driver.

Questions about this item

How warm does the P300 256GB get and how much power does it draw when running all day?

The drive is rated for 0°C to 70°C operating temperature, draws 2.07W active and 0.37W idle, and ships without a heatsink.

What slot and protocol must my motherboard or laptop provide for this M.2 2280 NVMe drive to work?

An M.2 2280 key-M slot wired for PCIe Gen3 x4 with NVMe 1.3 support is required; no DRAM cache is on-board, so host memory buffer is used.

Will the P300 256GB work in an older system that only has PCIe Gen3 x2 lanes?

The drive needs a full x4 link for its 1700 MBps read and 1100 MBps write; on x2 it will fall back to lower speeds but remains functional.
