Ok, thanks to all for the comments, tips, suggestions and links.
I bought one as my local Best Buy had one in stock, the 8 Gig X2 Pro which handles Raw files, can direct connect to my tablet etc.
I set it up last night... For MY use, I am pleased... I wanted a Wireless Preview on my Samsung Tablet (Android) when shooting in my little home "studio". Also wanted the ability to take on assignment remote, without wireless and direct connect to my tablet for preview in the field. I just had a recent field shoot that those which looked good on the camera view were not as exciting when I got home..
I installled all (went ok but there were some burps, parts not clear and I am not too smart.).
I tested shots and they worked fine coming into my tablet, using my home network. I then went down to the little studio and tested and pictures showed up fine on the tablet. I did increase screen on time for the tablet.
Today, I took some at work.. tablet was at my desk. As soon as I returned, it synced up and transferred the 9 shots. Then I shot some in the qc lab and they seemed to work fine. There is a lag until it syncs up and then the transfer is pretty quick. Keep in mind, I am shooting RAW...
Then I did a timed test.... shot 4 pictures
Sync Time (until I get the d/l symbol) 25 seconds
1st phot (including synch) 44 seconds
2nd 15 seconds
3rd 15 seconds
4th 14 seconds.
Total time from snapping 1st pic until 4th is displayed was 1:28 including initial Sync ( I think sync is faster on my home network.)
For purposes of my preview this is plenty fast enough... I consider the tests a success and the product adequate for my needs.
I will d/l the cards as I always have to main computer with Lightroom when the shoots are over where they go into directories by date and then edited are stored by month.
Would I buy this as a primary card?? No, but for what I want to accomplish it works great and will hold 300 Raw Photo's.
Again, thanks to all at Nikonites for the comments and thoughts....
