Disk
The machine was supplied with a 512GB PELADN-branded NVME SSD.
Here are the results with KDiskMark, an open-source benchmark software for storage devices. It’s a GUI tool that uses fio, the Flexible I/O Tester.

The PELADN WO4’s SSD delivers solid NVMe performance. KDiskMark reports sequential read speeds of 3,154 MB/s and sequential write speeds of 2,605 MB/s, which is in line with a decent PCIe 3.0 NVMe drive. Random 4K performance is more modest, particularly the Q1T1 read result of 56 MB/s, but overall storage performance is perfectly adequate for a low-cost mini PC.
Overall the SSD is quick enough for everyday desktop use, application loading, software installation, and general file transfers.
The PELADN WO4 ships with Windows 11 Pro, so I also ran CrystalDiskMark before installing Linux to compare the SSD’s performance under Windows.

Summary
Overall, the PELADN WO4 is a capable budget mini PC with strong CPU performance for the money. The Ryzen 5 5600H still has plenty to offer for desktop use, software compilation, compression, rendering, and other CPU-heavy workloads. But the supplied single-channel DDR4 memory and weak integrated graphics mean it’s much less convincing for memory-heavy tasks and 3D workloads.
In the next article, I’ll examine the PELADN WO4’s power consumption, looking at how much energy the system uses at idle and under different workloads.
