SanDisk Extreme

Marking a new high in microSD card capacities, Western Digital has started shipping its flagship SanDisk Extreme 1 TB microSDXC card. This is the company's (and industry's) first 1 TB microSD card, and while the $450 launch price is definitely steep, for portable devices that need a massive amount of storage in a thumbnail-sized removable card, a full terabyte is the biggest step up yet. When it comes to performance, the memory card is thankfully a member of SanDisk's higher-performing Extreme line, so performance isn't too pokey for reading and writing a full TB out of the drive. Formally, SanDisk rates it for read speeds up to 90 MB/s and write speeds up to 60 MB/s when working over a standard UHS-I interface. This works...
