I see a lot of adverts for portable USB storage systems that claim they are super FAST, but the numbers they quote are not all that fast.
As a reference data point, here are CDM speed tests for two portable USB units that I assembled myself.
Acasis enclosure, 2TB Samsung 980pro inside. Exfat.
Ugreen enclosure, 4TB Sabrent Rocket 4-Plus. NTFS
I created an 8-minute video the Cumbre Vieja eruption during which a new lava tube is just beginning to flow.
A link to my Flickr account is in my bio.
Click on the PHOTOSTREAM button.
The video will be the #1 item shown.
If you can, watch in full-screen mode, on a large monitor in a dark room.
(I believe playout is at approx 6Mbps.)
