Samsung? I don't really like them and I prefer not to buy their products. Still, they were the cheapest offering an 32GB Class 10 microSD card, so I decided to give them a go.

Specifications.

This is a microSD card originally designed for 4G phones and tablets. Samsung made it schock proof(it can handle a pressure up to 1.6 tons), water proof and magnet proof(when used near home cinemas etc.). We didn't test the calimed facts and we hope we will never have to verify them. 32GB should be enough for 8000 photos, 8 hours of HD video or 8000 songs, according to Samsung.

Packaging.

The whole thing comes in a simple paper packaging which can fit in an envelope which makes shipping cheaper.

Once unpacked, there are not much accessoires Samsung is giving us.

The card came formatted as FAT32 which means file sizes are limited to 4GB. Formatting to NTFS, which is(in my opinion) much better, went just fine. Please note that not every device can handle NTFS properly. For instance, Gen9 devices can only read it, that means you can't remove or add files.

Performance.

We tested the card using the CrystalDiskMark 3 and got the following results:

Benchmark	Read	Write
Sequential	20.06 MB/sec	11.85 MB/sec
512K	19.78 MB/sec	11.50 MB/sec
4K Queue Depth=1	4.675 MB/sec	1.273 MB/sec
4K Queue Depth=32	4.890 MB/sec	1.289 MB/sec

We also dit two tests with transferring movies:

8 movies of ~620MB each, 4.73GB total. It finished the job in 7 minutes and 10 seconds which comes down to average transfer rate of 11MB/sec.

One movie of 6.56GB was copied in 9 minutes and 40 seconds which comes down to average tranfer rate of 10,9MB/sec.

We quickly compared the results to 16GB SanDisk SDHC Class 6 card and found the results nearly the same, though with smaller files, Samsung card was faster. The SanDisk microSDHC 32GB card…

I have seen a few adds for these,I have no idea what class/speed is required for video playback etc, Class 4 are significantly cheaper.

It depends on which brand you are going to get(Most of the times, SanDisk performs better than is written on the box) and what video files you want to play. Actually, class 4 should be enough for video playback, but for recording at 1080p you better look for class 6/10/UHS(UHS is overkill) cards. I recommend looking at the bitrates of files you want to playback and then choosing the class based on that.

Another point is that copying files from the pc goes much faster with Class 10(we got write speed of 11.5MB/s, but 10MB/s is promised by Class 10 standards), Class 2 has write of only 2MB/sec, so it will take you ~5 times longer(on very small files, there won't be much difference).

In my country, the price difference with Class 4/6 was only a few euros, so I decided to get a more futureproof card. 🙂

Ok, Thats interesting,I am aware of course of varying write/read speed with different cards, My video files vary, I dont think any exceed 720p,Probably best to not go below class 6, I think there are some comparisons of brand differences on Toms Hardware.

I think you should be able to find some comparisons. 🙂 For 720p playback class 2/4 should be enough, but to be futureproof; you can better look(like you said) at class 6 and above.

I don't which country you are from, but here in NL, the Samsung we tested was only 5 euros more expensive than the SanDisk class 2 card. The Adata UHS-1 card was also a nice option(37 euros only), but I think it is really overkill for now. 🙂

Hi,

I just went on the Samsung site went to this card, and there it said:

Will this accessory work with my Product, and in a box next to it I typed:
Archos Arnova 7b G2 and it said

"Your Product is not compatible!
This Accessory is not guaranteed to work with your product"

So then I just typed in Archos and received the same reply, can someone tell me if they are running this card in the same tablet as mine and if it works?

Thanks.

dont quote me on this buy i think this card is fine. most sites for some reason dont even register archos/arnova as an official brand they tend to leave it out. i would think that it is just not in the database so returns an incompatible message, i would think it as a "brand not recognized" message

Hi,

The Arnova 7b G2 has a microSD slot which is SDHC cards compatible. I don't have an 7b G2 now, but all the Archos devices I tried recognised it. So, it should work. The only problem could be the max read/write speed, but I think that becomes a problem when you are looking at UHS-1 and higher cards(the card will still work, but at lower class).

Hope that helps. 😉

Hi,

Thanks for your reply 🙂

It would be nice to know if the Class 10 card would definitely work in my 7b G2, I don't really want to spend £30 on a card and then find out it is not compatible, I could go for a Class 6 but would prefer the Class 10 as it would be more future proof and better for watching films.
Do you think it is worth opening a thread as asking if anyone has tried it?

Class 10 will definitely work, It can just work at Class 6 speed... You will still be able to access and read/write the files on it, but at slighlty slower speed. Still, I don't think that is the case, because I didn't have any problems with my devices and I assume Arnova 7b G2 supports at least up to Class 10; UHS-1 cards could be a problem. Well, if it turns out that the 7b supports only up to Class 6(Again, I don't think that is the case), then you will benefit from the higher class with your next phone/tablet/camera. 🙂

I don't think it's necessary to open another topic, this one is quite appropriate for discussing about micro sdcard compatibility.

I'll have a look on our Arctools benchmarks if I there are any test data for that Samsung card on an Arnova 7b G2, will let you know.

When looking closer at Arctools benchmarks, I found 18 tests using that SDCard model, there were unfortunately no tests run on Arnova G2 in my data, most benchmarks were executed on Archos Gen8 devices (A101IT, A43IT that's exelletor Wink , A70IT).

As exelletor said, there is no reason it shouldn't work on the 7bG2.

Hi again exelletor,

I hope you can help, I have just received my Samsung 32 GB Micro SD card, can I just put it straight into the tablet?

Also which is the best way to download load films and music, should I plug in Arnova 7b G2 and drag the films/music to the Video/Music folders on the Arnova or to the SD card folder.

One last thing, is it better to use the adapter for the SD card, insert this into my computer, download the films/music onto the SD card, then put the SD card into the Arnova, the only reason I'm asking this is I wanted to know if the card needs to be formatted or I can use it straight away.

Thanks in advance for your help 🙂
