Improvements in the Echo 21 compared to the Echo 20

• PCIe Data Transfer Speeds: The Echo 21 unleashes the native speed of the internal M.2 NVMe storage slot, achieving up to 3,300 MB/s compared to the strict 800 MB/s ceiling on the Echo 20 forced by Thunderbolt 4's lower PCIe allocation boundaries.
• Pro Networking: Built-in network capabilities jump four-fold from 2.5GbE to 10GbE, adding native Audio Video Bridging (AVB) support crucial for modern macOS audio/video production pipelines.
• Display Handling: The Echo 21 features both an onboard HDMI and a DisplayPort connection natively, managing significantly higher multi-display configurations and refresh rates up to 500Hz using the asymmetric 120 Gbps bandwidth allocation mode.
• Flash Media Integration: The Echo 21 adds a dedicated microSD card slot alongside the standard SD slot, removing the need to carry external microSD adapters.

Notes:

• M3 base model MacBooks can support two external displays in closed clamshell mode.
• Some Core Ultra 1 and Core Ultra 2 systems may limit 4TB and 8TB SSD speeds to approximately 800 MB/s. Full performance is expected with 1TB and 2TB SSD models.
• Charging rate varies according to overall power usage. When sleeping, connected computers supporting Thunderbolt charging will charge to 100% through the dock.
• 2.5GbE and 5GbE speeds are supported when connected to NBASE-T compatible multi-Gigabit switches and NAS systems.
