SD Card Write Slow error

[Ansia]

How do you guys verify the ability of the SD Card? I'm talking about the displays you post showing the Card's abilities? Thanks!!!

Download the speedout software.

I'd go with CrystalDiskMark 7.0.0
Speedout hasn't been updated since 2013 from what I can see.

That's because it's perfect since 2013.

There are a few apps to check the SD Cards like SpeedOut...I use that and another free one just to be sure of the reading/writing speed.

When I google speedout all I get is screw extractors....

Using Speedout I made some disturbing discoveries.

I had been getting the "slow" warning when shooting video using the Sandisk 32GB V30 card that came with my E2P..... Speedout says the read speed is 17.3 and write speed is 16.2

I tried using a Sandisk 64GB V30 card that I had previously used in my XSP. Once in awhile I'd get the warning but not quite as often. Speedout says the read speed is 24 and write speed is 15.5

Wife bought me two 64GB V30 Netac cards. Speedout says the read speed is 30.3 and write speed is 18.6.

So my wife's Amazon purchases exceed what is sent with the Drone......

Again, excuse my ignorance, which is most important, read speed or write speed? Thanks!!!

 

[Tufargon]

Write speed is more important because it's writing files/videos to the card. Reading would only be for like watching your vids directly from the card. I always just transfer everything to pc to view.

I do too. Thanks again.

I've only flown once since getting the netac cards. Shot two videos of about 4 minutes each yesterday and didn't get a "slow" warning.

Sounds like you found a winner. Wish I could find time to fly my new bird. It's always either too windy, raining or I have a ton of things to do.

We've had horrible wind this year. I am Blessed to be Retired so I can pretty much fly on good days.

Winter here is usually windy. I'm not retired but I take care of and live with a bed ridden 80 yr old so me leaving to go fly doesn't happen often. Sold my XSP and got a MA2. Only flew it twice so far but it's incredible.

That is odd, I've never had video lag even with all the warning messages I've received. I shoot in 4K all the time and 8K a few times.
Have you used the V30 card the drone should have come with? Maybe reach out to Autel and see what they say.

Looks like my computer (is an old one) is the culprit. I just open the video in anothe application and the video was perfect. When I say perfect it means watchable (its that a word? English is my second language...)

Sounds like your SD-card reader is on a USB 2.0 bus... My 128 GB Samsung EVO+ does around 95MB/s, yes, that's megaBYTE per second in my macbook, but drops down very quickly in my friends' Windows laptop, where the USB card slot is connected to the USB 2.0 bus. It only manages around 20MB/s then...
