SanDisk 400GB Ultra microSDXCUHS-I Memory Card with Adapter

I bought this to put into my phone so I could have the freedom to throw in whatever games, movies, pictures, etc I want. Having owned a Nexus 4 which was locked in at 16 GB, I've been rather cramped in storage. Thankfully the Razer 2 recognizes up to 2TB SD cards if I'm not mistaken, but the 366GB capacity this card gives me after formatting will more than suffice. All buyers should make themselves aware that storage devices need to use part of their own memory to build the file system for the device to find the data on the card, so you will always have less than the advertised capacity(see the fine print on devices that says "actual capacity may be less"), at least with today's technology. Had a strange issue with Android's OS reading the card. For some inexplicable reason it reports the card as having 512 GB capacity under the storage settings. Thankfully, when I connect the phone to my PC in data transfer mode, the PC reports the proper formatted capacity of 366 GB, so it SHOULD be a legitimate card. It made me wonder if I had gotten a fake card before I plugged it into the PC, since counterfeiters commonly hack lower capacity cards to report a higher capacity than is actually on the card. With that in mind you can understand why I might a hacker meant to write 400 GB to this card but forgot they set their program to write 512 instead, or something of the sort. The average user assumes the card must be legitimate if it say's it has the amount advertised. This is not the case, and the device using such a card may wind up losing data because it's trying to write to memory that's not actually there. By the time the user figures out it's a fake, the counterfeiter's account on the store is usually shut down. Thankfully my card seems to be legitimate.
