Is that your grandad's transistor radio? No, it's a 4-SSD NAS with two 2.5Gb LAN ports, 12GB RAM, and a cracking name — the orange-colored Youyeetoo NestDisk

• Youyeetoo NestDisk has four M.2 slots, three using PCIe 3.0 x2 and one supporting SATA3
• Interface bandwidth limits prevent high-end SSDs from reaching full speed
• SSD thickness of 7mm is recommended for physical compatibility

The Youyeetoo NestDisk is a compact mini PC built around four internal M.2 2280 slots, all intended for solid-state storage.

Three of these slots rely exclusively on PCIe 3.0 x2 links, while the fourth also accepts SATA3 drives.

These interfaces offer limited bandwidth, so higher-end SSDs will not reach their theoretical performance ceilings.
