Micro SD cards and H2testw results

[kamkar]

Figured i start a thread about SD cards and ther performance as logged by H2testw.

I figure 1 post per person and just update that one as you go along.
Please post a good close up of the card and add H2testw result below.
If you have results for simmilar cards allready posted by another guy, feel free to post them allso, you might have other results, and if not it will indicate a good stable memory card.

I've got the 128GB version and get the results, that can't be correct right?

I think larger cards might be a little slower than a similar smaller card, but that there look like a fake card ( something slower being re branded )

Are you testing card in the camera ??
You have to test it in a good USB card reader so you are sure you can get peak speeds, those speeds look like the ones i allso get as max speeds off the camera in mass storage mode.
All cameras seem to work as really slow card readers in mass storage mode.

My card reader i test with is a USB 3.0 from kingston.

 

[dirkzelf]

yeah i don't have that, just the cardreader in the pc.... its a full size reader so i tested the card with an adapter....

I also tried with Meenova Micro sd card reader, in USB 3.0 slot..... same results....

how am i gonna find out now??

 

[kamkar]

Hmmmmm thats a good question, do you get more or less the same speeds with other cards you test, or do you have other cards that can do faster in the same reader ?

If other cards can do better in the same reader then it must be the card that's a fake.

 

[dirkzelf]

on closer thought I think it is not a fake, others perfome below, the Samsung EVO 64GB tells me some 14MB, this one Kingston 17.7MB, but it's U3 card, should write 80MB.....

bouht here:

http://www.ebay.nl/itm/401098266142

seems reliable enough....

 

[kamkar]

Yes the card should perform a lot better.

maybe its the software / hardware that don't like each other.
Have you tried other drive benchmark software ?

Too bad we are so far apart or i could have tested it for you in my reader, there is definitely something fishy here with the speeds you see.

 

[dirkzelf]

they seem original enough I think.....

Any benchmark tips?

 

[kamkar]

I cant remember what they are all called, crystal mark - atto and what not pop up in my mind, same software used to benchmark / test hard drives should be able to do SD cards too.

How can I be sure about these values to be true?

Is my PC's cardreader/interface just not fast enough??

 

[kamkar]

I too got pretty poor speeds off my old USB 2.0 reader, that's why i upgraded to the kingston one.

Thankfully these card readers are not that expensive

There must be somthing in that reader you use that hold the SD card back

https://en.wikipedia.org/wiki/USB#USB_1.x

You may have the reader on a USB3 port, but inside the reader it only transmit with USB 1 or 2 speeds, and according to wiki USB 2.0 max out at measly 35 MB/s

USB 3.0 is maxed out at 400 MB/s i think it say

Dýa think these are ok then?

If you want it to be really fast then you want USB3 for the USB side and U3 for the microSD side.

The first of those ebay links says U1 so it should be reasonable but not fast, the other says nothing for the microSD side so is probably no faster than reading from the camera.

A slow card reader still reads good data though, if you don't need to read really fast then a really fast card reader is not necessary.

 

[dirkzelf]

the Kingston is spec'd at 80Mbytes write, both card readers specs at 5Gbps so I should be covered then?

I just did a disk test with an external USB 3.0 HDD and it writes >130 MBytes, so the PC's USB port is OK.

 

[dirkzelf]

ended up buying this one, faster delivery from UK than from HK....

So, I received the SDXC reader, that's supposed to do 5Gb/s, and these are the results I got:



I don't think that's good enough for the

Damn that's just getting weirder and weirder down there.

If you like to you can mail a card to me and i can try to test it here on my rig that as it can be seen can do the full speeds of the fast U3 cards.

Have you tried to contact the seller ?

 

[Nigel]

What figures does H2testw give?

Yeah, no response yet. I have to declare that I did short test runs, (500MB/1GB) so I am doing long test now with CrystalDisk (32GB), still running now.

Have done the short h2testw (500MB/1GB) and did even worse.

Both were in the front USB port, I'm trying the long run test in the back ports that are directly on the mainboard, maybe there's a cause there....
