Bests & Worsts Reviews from Amazon

I do not see any reviews for the 200 GB version of this card so I'll do my best to let anyone interested in purchasing it know what I'd want to know. I purchased the microSD card to fit my entire 160 GB music library on it to take with me on my Galaxy Note 4. . The actual useable storage is 183 GB due to how storage space / gigabytes are computed (see the comment section for more but bottom line you have 183 gigs available to you). It was definitely enough so no issues). It took several hours to transfer all the music from a USB 3.0 flash drive (256 GB) to this microSD card that I put in the phone (the flash drive was in my Surface Pro 3 i5). Once the files were copied they played fine though Poweramp. No issues with playback. I can't comment on video playback as I'm not using it for that. Its new tech so back up anything you don't want to lose (actually a back up of important data is always a good idea) but a 10 year warranty should be enough peace of mind (assuming Sandusk honors it). The card does its job perfectly thus far. So if you need 200 GB this will do fine if you are willing to pay a premium. 4.75 stars as I think the transfer time should have been a bit faster. Still going after 8 months though so I added a quarter star.
