Does the Echo 20 come with an SSD?

No. The M.2 NVMe slot is empty and the SSD is sold separately. It accepts drives up to 8TB.

How fast is the internal SSD?

Sonnet rates the drive bay at up to 800 MB/s, which is fine for backups and media but slower than a native internal NVMe drive.

Can it charge my laptop?

Yes. It provides up to 100W of charging power over the Thunderbolt cable, enough for most laptops.

How many displays can it drive?

It has one HDMI port at 60Hz plus Thunderbolt 4 ports that can carry display signals, so multi-monitor setups depend on your laptop and adapters.
