Even better, this card behaves well under stress testing, with sustained full-card read/write speeds of 74MB/s and 36MB/s. Cheap cards often will slow down after a few GB written, but this one remained consistent throughout the entire test.
The card comes the usual full-size SD card adapter, but like most SD cards nowadays, a storage case is not included. The 2-year warranty is shorter than what some manufacturers offer, but I'm okay with that given the card's affordable pricing.
Overall, this speedy microSDXC card would be a great choice for a phone, handheld game console, or Raspberry Pi. Recommended.

I didn’t subject it to a variety of techie performance, write speed, temperature, water immersion, EMI or other tests that those of a nerdier inclination might be interested in. But after I inserted the microSDXC card into the included SD adapter and reformated it to the NTFS file system (it comes formatted to exFAT), I popped it into my Sony DHS-W350 14MP digital camera, where it worked flawlessly to record still images and videos.
That’s good enough for me. It works, it’s cheap and I’ve got another memory card to add to my stash. I’m sure I’ll need it one of these days.
I ordered this for the capacity, which is currently really adequate for most things…cell phones, dash cams, surveillance cams. I wanted (another) 128 GB SD card for my multiple devices that use them. I see that others have run bench tests and claim that this card runs a little slower, and others claim faster. Unscientifically, I’ve not generally noticed a performance deviation from my other cards either way; it just works. Though if I had, I would’ve run a bench test (No disrespect intended to those reviewers that did…you saved me time from doing so just on principle…so thank you.)
Bottom Line:
Good capacity for (current) price…it works just fine.

2~3日で書き込み速度低下の警告がでます。
使用を続けると、書き込み失敗した可能性の警告がでる時があります。
128GBはCLASS10 U3 V30、最大書込速度65MB/s、高性能な部類に入ります。
交換前に使用していたSanDisk64GBカードも最大書込速度65MB/sですが、
警告は出た事がないので残念です、次は書き込み速度をもっと上げて選びます。
