Resolving confusion between "Mobile Ultra" and "Ultra" SanDisk,
Verified Purchase(What's this?)
This review is from: SanDisk Ultra 64GB MicroSDXC Class 10 UHS Memory Card Speed Up To 30MB/s With Adapter - SDSDQUA-064G-U46A [Old Version] (Personal Computers)
The last few days I have been diligently shopping for a MicroSDXC card to utilize in my new smart phone. I have a long term positive experience using SanDisk cards. I quickly became confused about the differences between the so called "Mobile" Ultra cards and the Ultra cards. The performance specs to my "intermediate tech experience" eyes were virtually the same. The prices were also similar, with the "Mobile"version slightly higher. To finally resolve my confusion I contacted SanDisk technical support. To my surprise, the "Mobile" version is the older, no longer manufactured version. The Ultra is the current model. So I immediately bought the current Ultra version, which very fortunately AMAZON had on sale!
