Compact M.2 2280 NVMe drive for laptops and desktops

The Patriot P300 512GB SSD uses a PCIe Gen3 x4 interface with NVMe 1.3 to deliver up to 1700 MBps sequential read and 1200 MBps sequential write. Random performance reaches 290,000 IOPS read and 260,000 IOPS write. The DRAM-less design relies on Host Memory Buffer technology and NANDXtend ECC for data integrity.

Sustained workload behaviour without a heatsink

Operating between 0 °C and 70 °C, the drive draws 0.37 W idle and 2.07 W active. End-to-end datapath protection and wear-leveling firmware maintain consistent throughput during extended writes. The 160 TBW rating reflects the endurance available for typical consumer workloads over the drive’s service life.

Upgrade from PCIe 3.0 x2 or SATA M.2 drives

The x4 controller provides roughly 25 percent higher transfer speeds and IOPS than standard PCIe 3.0 x2 solutions. The jump is worthwhile when moving from a SATA M.2 SSD or an older x2 NVMe drive in a system limited to PCIe Gen3. Windows 7, 8, 8.1 and 10 are supported, with a possible driver requirement for Windows 7.

Questions about this item

How much heat and power will the P300 512GB drive produce during all-day use?

Active power draw is 2.07W with idle at 0.37W, and the drive is rated for 0°C to 70°C operating temperature without a heatsink.

What must my motherboard provide for this M.2 2280 NVMe SSD to work?

An M.2 2280 slot wired for PCIe 3.0 x4 and NVMe 1.3 support; the drive has no DRAM cache and relies on host memory buffer.

Will the P300 512GB drive work in a system limited to PCIe 3.0 x2 lanes?

It will function but at reduced throughput; the drive is built for PCIe 3.0 x4 and delivers 25% higher transfer speeds than x2 solutions.
