i have a SDXC micro sd but its incredibly slow compared to my old SDHC.
my old unbranded generic 32gb SCHC gets like 40 mb/s and its a cheep SD

then i just brought a new Official Samsumg 128gb SDXC sd card and it only does 8 mb/s
why is my cheep sd better then my branded one?

the packaging says up to 48 mb/s with UHS-1.

sorry i forgot that the FAQ section is not for questions..

Are you using this in a phone, computer, 3DS, what? Depending on the device, the reader might be the bottleneck, or even it's driver if it's on a PC. A built-in SD slot on a laptop could internally be on a USB 2.0 bus, necking you right there pretty badly. The filesystem of the SD card also plays a role in speed. We need more details from you to answer you properly.

 

[acidmango]

does the packaging say 48MB/s is it's read speed or write speed?
Minimum write speed is still only 10MB/s on UHS-1.

I'm using is in a 3ds but that's not what I'm worried about its the speed when I put on my pc.

Here is the SD, not the exact one but the same make.
The benchmarks are terrible.

Did you get it on ebay? The link you shows looks like a fake card to me. Check the font spacing on 128 compared to this one:

 

[xdarkmario]

I didn't but that exact one but one sumular.
Fake branded SD cards eah?
Well i got a refund and they let me keep the card to no loss this time, so now I can experiment with it.
I didn't know I have to watch out for fake SD cards

 

[Megaben99]

Yeah there are a lot of imports that don't have the advertised specs. H2TestW is the gold standard - I doubt the card is a full 128 GB even.

[xdarkmario]

H2TestW wants to take 4 hrs 0__0
but im sure its fake, it was cheep but if i can use the 128gb but its just slow i can manage.
and SD insight says invalid

 

[Megaben99]

Ouch. Start it before you go to bed lol -- at least you'll know how big your SD card is. Like you said, still usable, but you would at least want to know the real size so you can plan around it.

 

[xdarkmario]

OMG its really only 7.8gb!?!?!?!?!?!? what a ripoff!! im glad his account was closed down and i got my refund!!

 

[Megaben99]

It really sucks. Back in the PSP days I got a 32 GB only to find out it was 1. Sorry your 128 was an 8, but at least you know. And you got your $ back!

Could have picked picked up an 8GB card for free with mouse purchase

Yeah, it was probably just a modified Class 4. I've seen plenty of fake SDs. I'm surprised it was even 8GB.

 

[Pedeadstrian]

Nevermind~

All things considered, hey he got a free 8gb card lol

Now I'm scared to buy SD cards.
Maybe I'll grab another microcenter branded SD. That one is superb.

Don't be scared to buy SD cards. Just be careful when dealing with less-than-reputable dealers. You may have to pay more, but the chances of getting screwed over from an official retailer on Amazon is much lower (if not gone).

Yeah, as long as you don't buy Kingston cards, apparently some QC failed/fake cards end up in legitimate shipments of Kingston cards.

Hmmz, doesn't work that way i also have 1 fake 128SD that really is 8GB, i tryed to fix it to it's original 8GB so it would show up the correct space, but it isn't that easy, the funny part, you can write at 120GB to it, but you can't read anything back always puzzled me how they do that

Well, you can reformat it to an 8 GB partition
Usually these fake cards have subpar memory quality though and you might get corruption, plus they're slow.

Amazon is a lot better, just buy from Amazon themselves or from the company that puts out the SDs. I generally go with SanDisk, which there are plenty of fakes out there of, and I haven't come across a single fake yet from there.
