TEAMGROUPTEAMGROUP A2 Pro Plus Card 512GB Micro SDXC UHS-I U3 A2 V30, Read/Write up to 160/110 MB/s for Nintendo-Switch, Steam Deck, Tablets, Smartphones with Adapter TPPMSDX512GIA2V3003

This 1TB Teamgroup microsd card tested at an even better than rated at nearly 160MB/s read/160MB/s write - but ONLY with one of Sandisk UHS-I microsd readers that supported their proprietary "quickflow" tech. Summarizing from the tech summary Western Digital published for it - it requires a compatible controller on the card and then can run it at higher clocks and data rates than UHS-I should officially support. Their whitepaper shows this can allow for up to 200/140 when the UHS-I bus technically can't do anything past 104MB/s. (UHS-II cards can do just over 300MB/s read and write, for comparison). This also doesn't just work for any card - I tested some other cards I had laying around and none of them got speed boosts out of the quickflow reader except for the TeamGroup cards and the Sandisk Extremes.If you see ANY UHS-I/V30 microsd card adverising at >100MB/s, it's likely using this tech to do it. That's the hard limit on the bus interface without workarounds.My theory is that either Teamgroup is buying and selling the lower binned sandisk extreme 1TB cards (which can do 190/130 with quickflow readers only). There aren't many true manufacturers of flash memory and controllers and I have no idea if Teamgroup even makes their own memory as their site doesn't says. I wouldn't be surprised if they were just a relabel of lower cost name brand castoffs as that's not uncommon in electonics.Why am I pretty sure of this? Well I tested with three other readers - a USB 3.0 UHS-I reader without quickflow, a USB 3.0 UHS-II reader without quickflow (to rule out that this is a UHS-II card sold as I), and a built in UHS-I reader in my laptop just to rule out the usb connection. All three got pretty consistent 98-100Mbps read and write which shows a few things - they hit the max bus speed for UHS-I, aren't actually UHS-II sold as a slower tier, and that the only explanation left is that they're at the very least using controllers with support for quickflow.It's interesting that Teamgroup doesn't mention this anywhere as it's the only way to get the max rated speed . Even their website just states a vague note that they can surpass the 104MB/s bus limit on UHS-I - and as far as I know all the other results in reviews here showing 90-100 read and write are the best you can hope for with a bog standard reader. Considering they also frequently sell for 2/3 the cost of the sandisk extremes and are often the cheapest 1TB card on the market I'm pretty pleased.I've been buying these in different capacities for raspberry pi projects for a year or two and had no issues with them. An important note though is that as noted you need a quickflow compatible reader in your PC (they're pretty inexpensive), but also support on the end device which is pretty rare, if it exists in anything. For me the faster speeds to fill up the card before transferring it to the Pi is the main reason it matters. It takes a long time to transfer 1TB of data at 60-80MB/s. It is however amusing that this tech even exists when UHS-II may only require extra pins and traces on the card in some cases.

Team group has been around for some time now. They have proven themselves to be reliable.Great compatability. Easy to install. Format is fast.Great value for the money.I have had these cards for years and the 1st ones I got are still working.The speed is amazing. I just started backing these cards up from my security cameras on my pc. Now you don't really need these speeds for security cameras, but its about how fast they back up to other media. Sitting there for 6 hours or less than a hour. That is why you want these cards.If you are going to use them for video or even high mp cameras for stills these are a must have. That is if you have a camera that uses microsd.

I had bought real inexpensive 1 TB micro SD cards and Got What I Paid For!. Did not lose a whole lot of money on them; they were worthless pieces of junk and inuseable. So be warned!Saw this card and diligently went through all the reviews and then others I came across on the web. I cannot comment on the phtographic aspect since my purposes were for Documents only. Whereas the inexpensive card would not complete the f ile/document transfer of 54GB; this TeamGroup SD card finished quickly within 45minutes!Checking over the transfered files/documents, there were no errors. I highly recommend this card for your file/document transfers; though, again, I cannot comment on the photographic usage of this card. More times than not, U truly get what U pay for; and in this case the higher - though affordable- price was worth the effort and time.

Read and write speeds works as advertised. I have had no issues with using this sd card and to my suprise it’s worked better than some of my other top brand sd cards. Will buy more again.

This card does not have anywhere near the full 2tb!!1,761.4GB vs 1,907.23GB on my SanDisk, or 145.83GB less or ≈2.5 hours of 8k 30fps in my Insta360 x5s. Needless to say, this will be getting returned. This is a big deal when you consider how much extra wear each flash cell will go through if you're using this for a dash camera or you record a lot of footage like I do.Iirc, this card was within ten dollars of the price I paid for the SanDisk (which has gone up in price since then, but i'm going to buy that instead even with the price increase).Reading other reviews, people are getting ripped off on other capacities as well.

Does what it says. I ran on loop for 10min. And these are the results. Took little bit to get here but i got it for the price its nice. I was bummed to read on there page that though this is for creaters and was i guess created by creaters.WARNING: Im not sure but i took a screenshot from teamgroups website about there warranty. As far as i understand using this to vlog will void warranty. So im not sure how this is made for creaters by creaters. Also using there sd card sucks. The micro is great but the adapter suuuucks. I went from 130 write and 150 read to 85 write and 89 read. I have a reader with a sd and micro sd ready. So i thought trying out there adapter be fun.

Works as expected. Easy to install and a good value.

Best SDcard for HiRes audio download. Captures rich details with dimensional info rendering realistic 3D audio images on playback....for hi fidelity DAPs (digital audio players)
