Kingston SDXC UHS-I 64GB, 128GB, 256GB

That's what I'm saying. Plus this isn't even class 10. Useless to me.

SanDisk or bust.

Hey Dizi, Not sure where you got your price from or which card you're referring to, but I'm seeing these for $48/$84.50/$145 for the 64/128/256 cards at B&H and other reputable dealers, better than Amazon by a few bucks. Massdrop's final prices are a decent ~ 10%/5%/7% below B&H's, and with free shipping and no tax, a good deal. That said, these are at the pricier end of SDXC cards, with similar specs from Lexar going for $33 (or two for $62) for the 64GB card; somehow Sony has the same thing for $29 (though I don't know who they source them from (no way Sony makes these)) . SanDisk's go for $53, so go figure. And Lexar's latest UHS-II SDXC's with a read speed of 150 MB/s are $45... But all of the above may be moot depending on your camera. I don't have a 4k camera (yet), but more importantly, my Canon 5D Mark III doesn't make use of the UHS standard, so I (believe I) am speed limited on these. Having an exFAT card is also not that important to me at this point. They do work with the 6D (on offer from Massdrop for a great deal) and with my Olympus OM-D E-M5 II, so it's possible that I'd pick one up....... But then I don't shoot much video and avoid putting too much data on any one card (usually I just use 16GB's) in case they crap out. (I hope people will not go too far into the "trust" factor--all of my CF cards are Kingstons and the only card that has actually crapped out on me was a SanDisk!) If I did have a 4K camera and/or shot lots of video, I might be in... Sorry for the long post and possibly for putting the kibosh on this one, but even an 18% savings (in this very low margin market) isn't enough of an enticement. Thanks anyhow Massdrop.
