Is Samsung better or SanDisk ? Also, an Extreme microSD in SanDisk is way more expensive than the Samsung microSD card you mentioned.
Ummm...
Nothing against SanDisk here.
I have a couple...the Samsung cards just seem very stable+never had any oddball error when benchmarking.
Where they really shine is with video transfer.
If a card can handle HD video across devices without glitching then they win with me.
Boils down to read\write stability after write burst.
A lot of cards advertise speed...great cards are stable across read\write operations.
Speed or writes per ms won't mean much if error percentage is high.
Samsung cards IMO are very stable meaning reliable.
Just a few thoughts there.
Good luck!
