TEAMGROUP 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

I tried to purchase from team group as often as I can because they have never let me down. These SD cards work amazing for just about anything. I have used these in cameras, raspberry pis, tablets, phones, and a few other odds and ends. These are very easy to use and have multiple format capabilities. It also has very good read write speeds for most things that you need an SD card for. The card is built well and durable whereas some I have used before from other brands are relatively flimsy. Overall for these SD cards they are pretty close to being the best priced as well as highest quality. I would definitely use this SD card as well as their other products because of the high quality and great price

Works well. Bought it when it was on sale for 100 bucks. Worth it.

This product does have 1 TB, and has been perfect for storing games for my steam deck. The only problem (which I should have thought more about) is that you shouldn't run windows on it. The card is not fast enough, and the physical port on the deck cannot go fast enough. Other than that, it is perfect for an SD card. Games will load slower than SSD, but that's just because it's an SD card ¯\_(ツ)_/¯

Good product, fast, no glitches.

I bought a TeamGroup Pro Plus 1TB MicroSD card back in 11/2023 for my Steam Deck OLED. It seemed to work fairly well for a few months. By the time I installed Diablo IV on it 7/2024, the card started showing massive issues. I noticed writes seemed to take forever, with patches for games on the SD card taking outrageous amounts of time, like 8-12 hours. Clearly, something was going wrong. Another abnormality was with games taking forever to load data; I noticed significant "pop-up" textures and world objects in Baldur's Gate 3. I considered the problems bad enough to make the games nearly unplayable. I decided to finally replace the card with a Samsung 1TB since those finally became available this year. I copied the contents from the TeamGroup card over to the Samsung card, which took around 15 hours, with reads averaging 15-20mb/s. Clearly a quarter of the speeds it should have been reading. Just to make sure, I tested the card with KDisk, and confirmed it's only reading at 28mb/s peak, and writing under 1mb/s peak. As best I can tell, the SD card is dying. I formatted it on a Windows PC with exFAT and tested once more with CrystalDiskMark, and it confirmed the awful read/write speeds, the same as the Steam Deck's KDisk benchmark. I put the card back into my Steam Deck, reformatted to ext4, (which took like 15 minutes, significantly longer than it did on first format) and it still benchmarked at awful speeds, even slower than the first tests. One minor side note: The 1TB Samsung Card formats with 8GB more storage than the TeamGroup 1TB. I'm sure it's the usual silliness of, "we have different definitions of 1TB" I usually hear. That's slightly less than a 1% difference, but it's still quantifiable. Summary: Maybe I just got a bad card. I'm willing to update this score higher if the warranty service is good, and the replacement works better. Edit 11-1-24: I sent the card in on warranty, and paid the cost to ship the defective card. To their credit, the RMA process was fast and they sent me a replacement within a week of receiving the bad card. The replacement works much, much better than the original as pictured. My best advice is to be aware these cards can overheat and degrade. Don't keep critical info on them, and if you do, have backups. Warranty service was good, so I'll raise my rating to 4 stars. I still recommend Samsung's 1TB card over Teamgroups, even with the big price difference, but if you need cheap low-priority storage, this should be fine.

After less than 2 years in a Win laptop, this 512Gb micro SD card began exhibiting performance problems. Winsat performance metrics showed: Disk Rand 16.0 Read: 1.11Mb/s; Disk Seq 64.0 Read: 16.31Mb/s; Disk Seq 64.0 Write: 9.29Mb/s; Avg Read w/Seq Writes: 2.89 ms; Latency 95th %ile: 120.68ms; Latency Max: 255.308ms; Avg Read Time w/Random Writes: 30.059ms. Those speeds are much worse than a mechanical disk. Bottom line is this card was inserted once in a laptop and stayed there. Moderate useage. Less than two years it became unsuable and had to be replaced. Obviously, not with another Teamgroup card. Would never buy again...doesn't last.

Has been on my insta 360 camera and it looks decent and working well. Plenty of space.

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.

First 1tb card ive ever bought that actually wasnt fake or doa.. flawless

ما واجهت اي مشاكل حاليا صح اني استعملها من يومين فقط ولكن اليومين ذي كرفتها كرف حتى خلصت المساحة نقلت كل شيء عليها وجربت رزدنت ايفل 4 ريميك و 2 ريميك و الجزء 6 وجربت تيكن 7 وقنشن امباكت كلها ما واجهت ولا مشكلة فيها وكمان طبعا سرعة شاشات اللودينق بتكون مو صاروخ لانها مو اس اس دي بس تبقى رهيبة على سعرها واسحبو عالسامسونج ايفو اغلى منها وسرعتها اضعف

問題なく動作してます。

Works very well with my oled steamdeck! After formatting I had about 920GB left which makes sense, its very slow to transfer your games over to it but every bit of the storage is usable.

I ran out of room on the existing 256 GB card in my Switch, so needed to upgrade to larger card. Picked this up at a good price, copied existing files from the 256 card to the 512 GB card and inserted into the Switch. Worked perfectly, and now have another 200+ GB of free space for more games. Very happy with the performance of this memory card.
