Patriot P300 (Regional) 1TB NVMe SSD Review

CrystalDiskMark is a useful benchmark to measure theoretical performance levels of hard drives and SSD’s. We are using v6.0.

For an entry-level drive, the P300 does surprisingly well in CrystalDiskMark QD32 test beating some higher-end drives. From looking at the two benchmark result screens, it seems that the controller doesn't have a preference about the type of data it's being asked to handle.

At shallow QD of 1, the P300 still performs well, particularly its write performance.

The latest version of CrystalDiskMark, version 7, includes a couple of profiles that can be used for testing – Peak Performance and Real World. The result screens for these two profiles not only display MB/s results but also IOPS and latency.

Looking at the Peak Performance results for Sequential read/write performance we could confirm the official Sequential read figure of 2,100MB/s, with the tested drive producing 2,135MB/s. Tested writes at 1,732MB/s bettered the official 1,650MB/s.

We also used CrystalDiskMark 7 to test the random performance of the drive at lower queue depths (where most of the everyday workloads occur) using 1 to 4 threads. The read performance climbs smoothly throughout the tested queue depths and threads.

In the 4K random write tests, the results are a mixed bag. Using a single thread, the drive climbs pretty steadily from QD1 to QD4 ending the test run at 204MB/s (49,898 IOPS). With 2 and 3 threads the drive peaks at QD 2 before dropping back a little while the 4-threaded test peaked at a QD of 1.
