Curious about sd card class 10 vs class 4 performance?
-
Hmm Im kind of curious about something...
I just went through my drawer and found a,
Kingston 16Gb Class 4 tho sd card and i want to do something with it.
I was thinking of making another Image or maybe put Amibian on it for some
Amiga gaming...
Now my question is will the class 4 do the job??
I know the class speed means writing but i can deal with slow writings,
But what about reading??
When you play a game its being read so will the performance be fine?
If not ill just toss it back into drawer and forget about it.. -
@RetroFreak89 for most games, the only slowdown would be loading them. Any cartridge based system will load the entire game into ram, so once they are running, there is no performance issues. Where you may notice are in cd based games, as those stream from the image. If the pi can’t read fast enough for those, the emulator will just pause to catch up.

But what about reading??You'll likely get a few opinions here, but I personally don't believe the class rating matters all that much. The rating is based on sequential read and write speeds, which is a valid benchmark for digital cameras, but computers read and write data non-sequentially. There are software packages that measure non-sequential read/write speeds and even sites that post results of those tests on common cards, but as the manufacturing can change on any brand, without any notice, I personally wouldn't trust any test that I didn't run myself.

@mediamogul well the sd card is a 16gb Kingston class 4 lol its all it says its probably pretty crappy

It's impossible to say without testing it first. Here's a link listing six free tools used for benchmarking SD cards. Afterwards, you can compare the speed to the cards listed here that were updated as recently as this October.

Or, you know.... write the image and test it. 🤯🤪
Certainly not going to damage the equipment or the card to try it out for yourself and see how it performs. Might cost you an hour of your time but that's it. 👍

@RetroFreak89 I've a Kingston 4GB (class 4) in my setup and it's a solid worker since more than 3 years. My ROMs are located on pen drive. So it's very easy to maintain system backups and separate ROMs. The class number says nearly nothing about the performance of a system setup. Because the class gives only information about write speed. So if I restore an image on a class 4 and on a class 10 (or UHS-x) then I see great differences... Read speed through all classes is about 10-15MB/s. Depends much more on the card reader device!
@mediamogul Thanks for the user friendly explaination. Maybe worth for a wiki entry.

@RetroFreak89 i first used several class 4 kingstons i bought at walmart and best buy. I got data corruption all the time on them. Went to samsung after that. Not a single data corruption on the samsung evos.
