Question 1

Does it work with iPhone 6?

Accepted Answer

Just add it to a card reader with a lightning connector like the Massdata Lightning iFlash USB SDHC Micro SD OTG Card Reader For IOS 9 iPhone 5 6 6S Plus iPad PC & Android and it works with both iPhone and iPad after downloading the iStick app from the App Store.

Question 2

What is the actual usable size of this card?

Accepted Answer

I have the 128gb card and use it for an android phone (I have an LG G Stylo). It had to be formatted first and then I got a total of 119gb of actual usable memory. Hope this helps.

Question 3

Does this work with the new Amazon Fire Tablet?

Accepted Answer

I don't know about this specific card, but the Sandisk Extreme Plus (red top stripe like this, but gold bottom instead of grey) 128 GB, V30, XC I, U3, A2 cards I have (multiple from different purchases but the same model), formatted to exFAT with 128 kb allocation units, have not worked at all in my kid's Kindle Fire 8" model.  I have not tried them in other kindles, but the model I just listed does NOT work.  Are you inferring that I'm pissed off, yeah.  That is a fairly higher end card.  Fast, sizable. meets all the common standards, stock formatted in about the most common configuration for cards.  Meets everything Amazon says is supposed to work that I can find (by the way, finding info on what is supposed to be fit-able inside my kid's fire table has been a pain, Amazon could do a damn better job of documenting their models and what is supposed to work with them).  And, a big goose egg.  What a waste.  No idea why the Amazon tablets suck so much.  This is simple software stuff that should have been fixed about 8 years ago with their 2nd or 3rd model and rolled forward from then on at no extra cost to the consumers (who deserved a working storage driver in the first place.  And yeah, all the SD cards work fine on every windows machine and the GoPros I have used them on, just the kindle is incompetent with it.   Maybe the slot on the kindle is borked?  Nope, it can see at least two other microSD cards just fine.  Really retarded.

Question 4

how do I know if I need the new version?

Accepted Answer

If you desire faster transfer speeds otherwise no need for new one
