The Celeron J4005 was used in the original AS5202T NAS. As the chart shows, the AS5402T’s N5105 processor offers a massive speed hike mainly because the J4005 only has two cores whereas the N5105 is a quad core processor. Note, the N5105’s single core performance is 26% faster which also accounts for some of the improvement.

CPU Benchmark

Our chart includes a couple of CPUs often found in NAS devices, the Intel Celeron J4125 and AMD Ryzen Embedded R1600. The N5105 offers better overall performance than either of these processors (although the R1600 single core performance is better). We’ve also included the Intel N100 processor in the chart. The N100 is gaining traction in mini PCs as it has very good performance for its class.

Some people subscribe to the doctrine that a NAS should just be used as a NAS. We don’t agree. It can also function as a multifunction server and even substitute for a mini PC. The AS5402T offers a built-in App Central to run a variety of software. And with Docker, Portainer and VirtualBox available in App Central, the NAS can run a huge range of additional software.

From our tests, the AS5402T is a capable mini PC in its own right. There’s tons of software that runs sweetly on the device even with its relatively low 4GB of RAM. But we recommend increasing the RAM particularly if you want to use say VirtualBox, or run memory-intensive software such as PhotoPrism.
