Team 64GB microSDXC UHS-I/U1 Class 10 Memory Card with Adapter, Speed Up to 80MB/s (TUSDX64GUHS03)

Pros: Team has been one of the go to vendors for micro SD cards because of their pricing and the lifetime warranty. I purchased this card for my Microsoft Surface. It is an added value and allows me to easily transfer large files to any of my home computers. At $43.99 a mere $1.45 per gig this SD card is a great value. Highly recommended.

Cons: None at this time.

Overall Review: Great little card for the money. Using Win 7 Pro, Home premium, Ultimate, and Windows 8 you need to make sure your reader supports SDXC.

Pros: Faster than advertised: Sequential Read (Q= 32,T= 1) : 87.743 MB/s Sequential Write (Q= 32,T= 1) : 32.874 MB/s Random Read 4KiB (Q= 32,T= 1) : 4.888 MB/s [ 1193.4 IOPS] Random Write 4KiB (Q= 32,T= 1) : 1.481 MB/s [ 361.6 IOPS] Sequential Read (T= 1) : 88.296 MB/s Sequential Write (T= 1) : 27.474 MB/s Random Read 4KiB (Q= 1,T= 1) : 4.614 MB/s [ 1126.5 IOPS] Random Write 4KiB (Q= 1,T= 1) : 1.343 MB/s [ 327.9 IOPS]

Cons: None as of this review.

Overall Review: Test Notes: Fresh MicroSD card out of the package at default format. Entry level W10 64 laptop (Atom class processor) CrystalDiskMark 5.1.0 x64 at default settings Transcend TS-RDF5K reader also available here in Newegg. I've read that it supposedly tops out at around 90MB/s. If it does, this reader may have topped out. My initial impression is that this is a very fast card and is a great value on sale at ~$30 as of this date. On a side note, I'm always pensive about how durable removable flash memory is but, we'll see how long this lasts. The lifetime warranty is a nice touch just in case things goes south.

Pros: Was not working long enough to report any pros...

Cons: Insert in my Fire Tablet and it recognized the memory first without any issue. Then I started to copy content to it. After about 2 hours the Fire Tablet just didn't recognized the memory card any more and all installation were lost. Another Sandisk sd card to check on my tablets memory slot works just fine. Checked also with the SD card adapter in my laptops memory card slot. Nothing anymore. Disappointing. Didi not last very long.

Overall Review: I will give a replacement a try and see how it goes.

Overall Review: I used it just a few times, then I used it on my trip to Norway and it pooped out and I cannot format it at all, I tried in cmd, with programs, with the gopro itself, it says its locked. Really sucks unfortunately. That being said I am sure if you buy this, you will not have the issue happen. Probably a fluke thing.

Pros: It's very small

Cons: Worked for about three days. Now any device i put it in says it requires formatting. If I format it then the device can't access it or the next time I power the device it says it requires formatting. I've tried it in multiple tablets, phones and card readers.

Overall Review: I would give this product 0 eggs but that is not an option. The price is low enough that the cost time and effort to return is greater than buying a new unit. I will never buy another Team memory product.

Pros: Came with an adapter? Newegg is great!

Cons: Dead on arrival.

Overall Review: Buy another brand. I bought this for a raspberry pi I'm working on, but my Windows Laptop could barely recognize the card. It would only even know it was plugged in sometimes. And when it did know it was inserted, I'd right-click to format it, which would freeze/crash my Windows Explorer window. I could never even open the drive in Windows, though it was listed under "My Computer" as an available drive - but clicking on it wouldn't do anything except freeze and crash the Windows Explorer window. Too cheap to return it, this thing is garbage. I've already ordered a name brand card as a replacement.

Pros: Big Capacity

Cons: Died quickly

Overall Review: My Original 64 GB Sandisk MicroSD is still working great and going strong for 7 years. Needed more capacity so I ordered this card but it died a few days after the 30 day return window.

Pros: *Fast transfer speeds *Seems well-made, solid *Price at time of sale was great *Packaging is sturdy *Comes with a full-size SD card adapter

Cons: *None to report

Overall Review: This card is working just fine in an HTC EVO 4G LTE Smartphone, just in case anyone has doubts, even though the 'official' word is that the device has a maximum supported capacity of 32GB. I'm tempted to try a similar card of 128GB in my phone, but really have no reason for it yet. Everything transferred fine from my Win7 x64 system to this card in a USB 3 card reader. I simply put this new card into my phone, formatted it with the phone, plugged it into my PC's card reader for transfer of everything, put it back into the phone, and all is well. I now have 2 times the storage to be able to better use my phone as a media player, with over 16GB of music and almost as much video on this card, with more to be happily added later. NOTE: Search forums or other user-based sources for details about what may or may not work with the device you intend to use this card with. While I found information on other brands of MicroSD cards up to 64GB working with my smartphone, it was the SDXC designation, and not SDHC, which prompted me to try this card for my device, as some others have confirmed. I took a small risk in buying this card for my device, but it's working just fine. Reported storage on the card by my device is 59.01 GB, which is normal and is a well-known limitation of filesystem allocation usage. Whatever operating system you use, it will simply NOT be reported as a full 64GB, but it will be close. This card ships with the exFAT filesystem format, which is immediately usable by current Windows systems, but may prove troublesome with other Operating Systems. Simply format within the target device or to FAT32, and it should then be usable to smartphones or tablets, and still usable in a card reader attached to a standard PC.
