Marking a new high capacity microSD card, Western Digital has started shipping its flagship SanDisk Extreme 1 TB microSDXC card. This is the company's first 1 TB microSD card, and while the launch price of $ 450 is definitely steep, for portable devices requiring a massive amount of storage on a thumbnail size of the removable card, a whole terabyte is the biggest step Despite the performance, the memory card is thankfully a member of the higher performing Extreme SanDisk line, so the performance is not too pokey for reading and writing a whole TB out of the drive. In a formal way, SanDisk pays it for reading speed of up to 90 MB / s and records speeds of up to 60 MB / s when working on a standard UHS-I interface. It works almost 3 hours and 4.6 hours to read and fill out the cards, respectively. In fact at this point SanDisk is heavily prohibited by the UHS bus; the card can actually be read at 1
With its propagated performance, SanDisk's Supersized card supports video speed in class 30, which despite other things means the minimum speed of writing must be at least 30 MB / s. The card meets the requirements for the A2 app performance class, meaning it can be complied with at least 4000 randomly read IOPS and 2000 randomly written IOPS, and supports capabilities such as command queuing and caching.
Unfortunately for tech enthusiasts, SanDisk is not saying about 1 TB card under the hood. Due to its capacity, the card is likely to be based on the company's latest 96-layer TLC or QLC 3D NAND memory. But in short, it's hard to confirm.
At the moment the new 1 TB microSD card can be used directly from Western Digital for $ 449.99. But eventually the products will also reach regular retail stores.
