Default SD card specs?

What are the performance specs for the SD card for the PDR?

For a typical 4hr HPDE weekend what size card is needed?

Does 1 brand work better than others?

I've heard the PDR card capacity is 4 TB. SanDisk is pretty much the standard for SD cards. Not sure how much space you'll use with the HD camera on the PDR in 4 hours. I'm guessing about 100gig's

Default Card Size ???

Nice but without card size the number of minutes is not helpful.

Depends on what partition table is used. 4TB is actually the physical partition limit of FAT32 formatted storage, if it's formatted with GUID partition table. On the C7 it is required to use MBR, or master boot record partition tables, and that limits FAT32 formatted storage to 2TB.

The video on the previous generation PDR is also 720p AND heavily compressed. If you want to be super conservative, here's a good video size calculator for storage space. Select H.264 and the resolution (in this case, I assume 1080p).

https://www.digitalrebellion.com/webapps/videocalc

4 hours of H.264 @ 1080p30 at highest quality setting yields about 180GB of storage. I suspect a 128GB card would be more than enough to store all 4 hours. Using the previous generation PDR as reference, if they use the same compression codec and ratio, assuming 1080p30 is roughly 2x size to 720p30, you can safely assume a 32GB card would be able to store 4 hours of gen2 PDR 1080p footage. On the safe side I'd get 64 GB or 128 GB.

I can guarantee you that's a 64 GB card.

You can get a 1TB card for $300 and it'll last a WHILE. You can get a 1TB card for $300 and it'll last a WHILE.

We were told at Spring Mountain no more than 32 gig and make it a speed rating of 10.

Will the C8 use a SD card or a USB flash drive? The trend seems to be towards USB these days (at least for vehicle audio).
