Silicon Power 128GB Elite microSDXC UHS-I/U1 Class 10 Memory Card with Adapter, Speed Up to 75MB/s (SP128GBSTXBU1V20BT)

Pros: It's a microSDXC card UHS-I rated. It did live up to its 75 MB/s billing at 72.67 MB/s transfer -- sufficient to fulfill almost all but the most extreme throughput usages. We used it in a security camera, tablet, computers, and handheld gaming devices with no issues. Overall, very pleased with performance and like that this brand is a few dollars cheaper than the more name brand competitors.

Cons: It's rare that I can say this, but with standardized and rather mature technology like this, the only potential con were data read/write and integrity issues. Throughout months of continue testing, wear and tear, and reformats, there were no issues with data ever. The only possible con was that it's UHS-I rated which provides bus throughput up to 104 MB/s, but the device was marketed as speeds up to 75MB/s, so this is hardly a con between the technical limits and the advertised speed. Still, worth noting, but no deduction as all brands advertise thusly.

Overall Review: As far as SD cards go, the technology is pretty standard and the components come from just a few manufacturers. That said, I hadn't used Silicon Power branded before and was curious if it rivaled other budget brands as well as mainstream name brands.

I was pleased with the performance and compatibility to any device I popped it into. There were no issues with fitment or compatibility and none was expected. I'd recommend this to anyone looking at microSD cards as quickly as I would any other brand.

Pros: - Fast large capacity card at a very modest price.
- Lifetime Warranty!
- Formatted exFat outta the box!

Cons: - Speeds vary and aren't too quick to read or write. Thankfully though, they're not too far from advertised.
- Pending your device and your use you may require a faster card.
- Full sized SD adapter doesn't mean this card will work in all devices.
*My Sony cam didn't like the adapter and the card was not able to be used.*

Overall Review: I bought a 128gb S*msung card exactly 4 months ago for $99.99. No lifetime warranty and not much faster than this card... Food for thought.

Overall though, I'd say this is a pretty good deal for the money if you need a pretty cheapo high capacity "do-it-all" type micro SD.
