Local performance needs to be established in order that the later network tests are meaningful.Ī fast 128 GB memory stick was plugged into one of the Pi’s USB 3 ports. This test measures how fast the Pi 4 can read and write to a local USB 3 connected drive (a USB stick).

Realistic testing exercises the full stack: file system, CPU, USB and networking. Real files were transmitted, rather than auto-generated block streams or “dd” images. That is to say, making the Pi do a realistic job and measuring the actual time taken. This article is about real world testing. Since the Pi 4 was launched, many sites have run the usual bench marking tools, and the results are widely available. Yes, the Pi 4 can push even a 1000 MB/s network to 100%. Sustained write speeds of over 68 MB/s were obtained, and over 105 MB/s for reading, including saturation of the Gigabit network. Is the Pi 4 the same, or can it operate as a serious NAS ? The Linkstation Live, the Sheevaplug and, to a lesser extent the Pi 3 are all on that category, unable to push their gigabit ports to more than about 14, 8 and 12 megabytes/sec respectively, due to the limitations of the CPU and the board. Over the years, many “home” devices have been launched with Gigabit Ethernet, promising lightning fast network speeds, only to disappoint due to their lack of overall grunt. It has 4 CPU cores like the Pi 2, a gigabit port like the Pi 3, plus USB 3, a better SoC, a separated bus architecture, faster memory and more of it. The spec is a big step up on previous models. The Raspberry Pi 4 was launched on 24th June and has been well received, to say the least.
