Patriot PXD 1TB M.2 PCIE TYPE-C Portable SSD Review

Performance

Performance has been tested on the latest Intel Comet Lake-S platform, which contains the i9-10900K processor and ASRock Z490 PG Velocita motherboard. All tests were performed in the Windows 10 x64 environment.

Let’s begin with the ATTO Disk Benchmark, which is one of the most popular applications designed to measure storage bandwidth.

Even though in the latest version of ATTO, we usually see lower than expected results, then the PXD performs quite well. The maximum read bandwidth is above the declared 1000MB/s while write bandwidth is slightly below.

In the CrystalDiskMark results are already better than expected. We can see up to 1060MB/s sequential read and up to 1030MB/s sequential write. What is even more interesting is that random bandwidth is exceptional even for M.2 PCIe SSD. Not many popular SSD can pass 50MB/s Q1T1 read while the PXD is going up to 70MB/s!

PCMark series benchmarks are showing amazing results for a USB drive. Many USB drives can’t even finish this test as it’s too demanding and generates errors on slow disks, but not the PXD. Our result is as high as that of higher series SATA SSD or PCIe x2 M.2 SSD. We have to remember that the PXD uses USB.

Below are also storage benchmarks made in the PCMark 10. Since most operations are random, then also our results are lower but, of course, really high for an external drive.

In the end, Anvil’s Storage Utilities, which is usually showing lower bandwidth but is still popular, so we are adding it to the list.

As expected, the bandwidth is not as high as expected but still pretty good and probably the highest we’ve seen on a portable SSD.

The PXD is simply the best USB SSD we had a chance to review. It’s really fast, so it should satisfy even the most demanding users.
