The SD card goes into the base (VMB5000). The minimum size is 16 GB. I haven't seen a maximum size, but there are posters here who have successfully used 512 GB cards.

Personally I use 128 GB cards. Arlo says the data rate is 3 megabits (which in my experience is high). But assuming that rate, 128 GB will give you about 95 hours of storage - (128*8000)/(3*3600)

This Knowledge Base Article states up to 2 TB; "Do not use the Arlo base station or SmartHub to format storage devices with more than 2 TB of storage capacity. The base station formats storage devices using the FAT32 file system, which supports a maximum of 2 TB of storage space. The formatting process reduces the capacity of larger storage devices to a maximum of 2 TB."

Do the new ultra 2 systems have the update to view the sd card online or do you still have to take it out and view on pc

I believe you are referring to the Direct storage access. You kind find more info here: What is Direct Storage Access and how do I use it?

True, but that is specific to USB storage, which is different from the microSD storage. It's possible that the upper limit of the microSD storage is less than 2 TB.

It'd be good to have a KB article that gives the max for microSD explicitly.
