Building a tiny 6-drive M.2 NAS with the Rock 5 model B

As promised in my video comparing SilverTip Lab's DIY Pocket NAS (express your interest here) to the ASUSTOR Flashstor 12 Pro, this blog post outlines how I built a 6-drive M.2 NAS with the Rock 5 model B.

The Rockchip RK3588 SoC on the Rock 5 packs an 8-core CPU (4x A76, 4x A55, in a 'big.LITTLE' configuration). This SoC powers a PCIe Gen 3 x4 M.2 slot on the back, which is used in this tiny 6-drive design to make a compact, but fast, all-flash NAS:

The Rock 5 B is not a Raspberry Pi killer—yet

Radxa's Rock 5 model B is an ARM single board computer that's 3x faster than a Raspberry Pi. And that's just the 8-core CPU—with PCI Express Gen 3 x4 (the Pi has Gen 2 x1), storage is 7x faster! I got over 3 GB/sec with a KIOXIA XG6 NVMe SSD.

It's still half as slow as modern ARM desktops like Apple's M1 mini, or Microsoft's Dev Kit 2023 (see my review here). But it's way faster than a Pi, it comes with 2.5 Gig Ethernet, it has two M.2 slots on board... and, well—it also starts at $150!
