SJ7 STAR Recommended Memory Cards

Toshiba Exceria 128GB WORKS good? for sure? not any problem at all?

 

No it seem like i did not test the harder things with the trancend 400X back then, so it is not recommended.
The Toshiba should be good, but just to be on the safe side i will pop one in the camera now and run it thru some tests to be sure.

Stand by for result.

 

NO the Toshiba Exceria 128 Gb card and any other size dont work in the SJ7 at least not with 4K and 1080/120 filming, 1080/60 appear to be fine,,, but thats useless.
I can only assume i have not actually tested those cards in the SJ7 but only the SJ6 air and legend

So you will have to disregard everything i have said aside for the 64Gb Trancend Ultimate 633X cuz that one work for sure in the Sj7 as its the one i have been using all the time.

Will have to test the Kingston U3 card that's in another camera for testing right now, but at least it have same read/write specs as the trancend 633X.
But it will be a few days before i can do that as i want to finish the test in the other camera ( dashcam ) first.

 

hi everyone,
is the sj7 works with
Sandisk Extreme PRO 32GB Micro SD
U3 V30 A1 ?

 

how long can you record 4k video with 32gb or 64 gb card?

 

Longer than a charge of the battery will last i am sure, but a precise number of time i cant come up with.

 

does samsung evo plus grade 3 64 work for 4k?

 

There is an easy way to figure out "how long at X resolution and Y frames per second".

All files, regardless of resolution and frame rate, can never be greater than 4 Gb. 1080 @ 60 fps takes about 14 minutes to make a 4 Gb file. Using that as a guideline, higher speeds and resolutions will take less than 14 minutes, lower resolutions or speeds will take longer. Just start the camera and see how long it takes to make a file. The best way to time how much video fills 4 Gb is to turn on the time of day in the video stamp, start the camera, and look at the time of day at the end of the file.

Use the Windows / MacOS file explorer tool to extract the properties for the chip to find out how much free room it has. IIRC a 32 Gb SD has something like 28 Gb of free space (file info, etc, eat up the rest of the space). 28 Gb divided by 4 Gb gives something like 8 files in a 32 Gb SD. At 1080@60, that's approximately 112 minutes of shooting.

The numbers aren't exact, but using these assumptions will give a reasonable estimate of "how much 4K can I put on a 32 Gb SD".

 

I wonder where the SJ people are, they been damn quiet since CNY.

Hope they are not still nurturing a hangover

 

still going strong with my PNY Pro Elite 128gb cards. Works in all my cameras without falter. Like them so much I bought 5 of them

 

Yes, its working perfectly!

 

For anyone thinking I'd like a bigger SD but put off by the cost of big SD's with long, long names, try a lower cost SD marked C10. Either the video is recorded or it's not. Maybe your particular choice won't work; my no-name generic 128's work quite nicely. So far, in a year of use, none of my SD's have failed.

It's your call, of course. I'm reporting only my experience.

 

Hi, just a quick check, what does the “grade” on the sd card means? And does Samsung Evo plus grade 1 64 gb works the same for sj6 camera too? Thanks in advance.

 

These are very fast cards and work very well in my SJ7 Star.
