I bought a Sandisk Extreme microsd card from these guys just recently.
The product specs are: 90MB/s Read, 60MB/s Write
However when I tried testing it using two different memory card testing apps, I got 33MB/s Read, 30MB/s Write… which is nowhere near the quoted figure.
Make your own conclusions about this, I'm still awaiting a response from the rep about this.
That has nothing to do with the seller
The manufacturer quoted speeds are theoretical under ideal circumstances
Not everyone will get those speeds
Also the batch and brand of the flash memory they use impacts the speeds
That has nothing to do with the seller
Cmon EC, how do you know they're not selling fakes? I understand that I won't be able to get the quoted figure, but to only get 30% on the read speed and 50% on the write speed is suss.
Especially when there's pictures on Amazon of customers posting results very close to the quoted figures (of the same card).
Send an inquiry to Samsung with the serial number of the card and report back with reply
Let's not assume the worse
Sorry I must make clear that this is my personal experience for a Sandisk memory card they sold me, so the Samsung memory card might be legit.
That isnt up to the buyer at all, it is the sellers responsibility.
If he has either a counterfeit card or a faulty one if its getting those speeds - its not up to him to do the leg work. He has reported the issue to SS and they need to resolve it.
There's a third possibility - he may be using it in a Raspberry Pi or some other hardware that doesn't support high speeds.
Even a 2017 flagship smartphone is likely to be a performance bottleneck for any card with read and/or write speeds that are higher than 50MB/s. The only thing manufacturers care about is that there's enough performance for whatever 4K capture options they've implemented. Beyond that they don't try to maximize SD read/write speeds.
Have you considered the device your plugging it in? My phone has a slow reader. You can only know by reading a faster card and comparing
I have a similar issue with MyMemory on their Toshiba Exceria card. I returned the card with documentation of my testing. If your laptop(on windows 10) has a built in card reader, just copy big files across and you should be able to see the write speed. Do the reverse to view the read speed. I received the replacement SD card a month later.
Was the replacement legit?
Yes it worked as per claimed specs.
Keep in mind that not every in-built card reader is fast. On my laptop, the in-built card reader tops out about 20MB/S. It's only when I use a USB 3 card reader that I'm able to get the speeds my EVO+ card can achieve.
With SD Cards, the Read speed is usually much faster than the Write speed. The fact that you are getting virtually identical speeds in both Read and Write seems to suggest that there is a problem with your test setup rather than the cards themselves. I suspect there is something that bottlenecks your speed to around 30MB/s.
How many different readers and PCs did you use for testing?
It may have been you…
How did you test though?
1) you can't do it in a phone because the phone's I/O performance is almost always the bottleneck (so you only end up measuring the phone's read/write performance and not the cards)
2) you can't do it with any old USB port with any old card reader because again something other than the card can be the bottleneck (card readers in particular can have variable performance — even when comparing a Micro SD slot to an SD slot on the same card sometimes)
For example if I test one of these 64GB cards from Shopping Square (I have one from a previous deal) in my S8, I see results that are significantly below the advertised speeds. But "proper" testing looks more like this: https://www.ozbargain.com.au/node/321411#comment-4974466
(real world transfer speeds are consistent with those results)
My conclusion, based on my sample (and others from Shopping Square / APUS Corp) is that they are selling genuine products. Grey import commonly, but genuine.
33MB/s Read, 30MB/s Write
33MB/s Read, 30MB/s Write
As per the comments above, try various things such as:
- testing another card using the same methodology
- testing using a different device/port (FYI when I used my USB2 port, all microSD cards were limited at 20 Mb/s. Plugged it into my USB3 and saw 90 Mb/s
wow so early to see a fight here just 10.40am
damn bought the "1" version for $20 not long ago, this is "3"
if using on the mobile phone will it matter?
Probably not. Maybe if you're recording 4K to it?
nah just taking pic not fans of video
Was confused about the total - thought it meant HKD and AUD, rather than the location. I decided an adapter for $6.45 seemed pretty damn expensive so went the HK option. Thanks!
would this be overkill for use in a Switch?
doesnt matter, it is cheap anyway
In terms of space, I'm already running out on my 128GB so I'd say no.
Are these legit or fake cards? I remember someone here saying they bought cards that were fake but I can't remember if it was shopping square or someone else.
I think I can recall someone saying that too, it was a long time ago though like the first comment on this post.
I got an evo plus 128g card from shopping square a month or two ago and it was a chinese grey import. it seems ok and I don't have any reason to question its authenticity, but the warranty is not covered in Aust, the seller offered a 12 month warranty in Aust, but when the card has a 10 year manufacturer warranty that was pretty crap. I won't deal with them again because if this, and the response I got when I complained.
Which sites that often post deals to here have the full 10 year warranty on sd cards?
any that are selling australian stock rather than grey imports will come with manufacturer's warranty.
Well I sent a private message to the rep yesterday questioning the speeds…however he has conveniently ignored it…
I'd say save yourself the hassle.
Even when the vendor is trustworthy it's possible that somewhere in the supply chain someone slipped in fakes or genuine cards are simply defective so it's always best to test any storage before use.
I use H2testw but there are a bunch of other tools: https://www.raymond.cc/blog/test-and-detect-fake-or-counterf...
I'm not flash on these guys after the great Xiaomi powerbank debacle earlier in the year. Hopefully Gearbest do a coupon deal on this one - they're only a couple of $ more without a coupon anyway.
i never have issue with both of them, SS and GB
What was the problem with the Xiaomi Powerbank? I just bought the 20,000mAh ZMI one. Are people having issues with it?
No, it's fine - there were a number of us on this site who purchased from them and it took literally months. They played funny buggers about the orders and avoided refunds until PayPal disputes were lodged. I was eventually refunded and purchased elsewhere. Pretty much the only online order I've ever had issues with in many years of online shopping.
thanks for the heads up.. this with the fact that it might be fake puts me off.
Is this good for an in-car dash cam? If no, can anybody recommend what is and if there are any deals in OzB?
I use these in my dash cam without any issues.
anyone know if this good enough for Mijia 4K Action Camera ?
Thanks OP, just bought a long overdue replacement card for my S7 Edge.
