My v3 is able to detect a 238 gb micro sd card but only records up to 9 days. I would think it could save more , maybe up to 20 days ?
Any help here , thanks

The V3 isn’t ready for 256GB cards yet, I get 11 days of HD continuous recording in HD on a 128GB card.

It’s 238 gb though not 256
Thank you carver . That was back in June , I assume you’re a Beta tester and have beta tested it ? Do you have any idea when it would be released ? Really need my v3’s to have bigger sd cards

I have not tested any of these fixes. We have had reports from some people with V2’s that 256GB cards are now working. in those. I don’t believe the V3 fix has been released to the public Beta yet.
This is a common misunderstanding from people in general. There are 2 different ways to count the storage space…Gigabyte is using the decimal system, so a GigaByte (GB) is 10 to the 9th or 1,000,000,000 Bytes; while a Gibibyte (GiB or just G) is using the binary system and is 2 to the 30th or 1,073,741,824 bytes. There is a 7.4% difference between the 2 measurements, but they’re basically the same.
Usually SD cards will advertise in GB or Gigabytes because of the way it rounds off the data it looks like more space, but they’re technically rounding off higher than it really is. 256GB is more accurately stated as having 238.4 gigs of space available when you’re not rounding off in decimal system. It’s almost deceptive that they claim to be 256GB, but we all understand better with the rounded decimal system instead of literal binary…but in reality, almost all files are shown in the binary system, not the decimal system, so people get confused when they see a file shows how big it is in binary-ibibytes, but then they are trying to think it’s being shown in decimal-bytes when files and folders are rarely shown in decimal-bytes…only the storage capacity.
That’s why Wyze doesn’t say “GB” and just says “G”
Because technically a 256GB card only has 238G or 238GiB of data that can ever be recorded onto the card. So a 128GB card only has 119G or 119 GiB of actual real data space. The card manufacturers just want it to LOOK like a bigger number, so they use the decimal version to round it all off to a higher number.
In this case, Wyze is using the more precise and accurate format as they should. 
This is a very good thing. We honestly wouldn’t be able to really trust the data if they were using GB instead. It would be confusing.
Though it’s a lot cooler to say “YodaByte” than yobibyte…so I can see the attraction to Decimal system myself!
Now you know.

Yep 238GiB on a 256GB card. Same amount of space technically. Just more convenient to speak in terms of Gigabytes even though it’s not quite right.

I read your post… Like 1.3E+2 times!
My head hurts now. 
Math much? 
Awesome tutorial though. Already bookmarked.

Thanks! I thought you might be one of the people to appreciate the explanation

Very interesting, knew there was a difference between giga and gibi, but never really looked into it. Good to know!

FYI @Rulwiz the fix for your 256GB is finally in public beta! If all goes well, it will be launched to production for everyone else soon! You’ll soon be able to use your full 256GB!

I have been testing the beta against another cam without it. Both have 256GB HE SD formatted by the cam.
With the Beta FW I am still building time since switching from the SD shipped xFAT to the cam formatted FAT32. I currently have 138GB recorded in HD @ about 15 days continuous. Still testing.
With the current Public FW, I am stuck at just over 83GB and about 8 days.
The Beta is in it’s 4th build test. You can follow the progress of the V3 Beta FW in the V3 FW Beta Release threads:

Update on my 256GB High Endurance SD card test in my Cam V3 running Beta FW 4.36.10.2632. So far stable operation with recording and playback.
Card began overwriting oldest footage today at 225.21G of 232.92G on the card.
Recording in HD continuously, video can be accessed back 24 days, 8 hours, and 20 minutes.
Almost ready to push the FW to the rest of it’s V3 buddies!
