The abundance of storage capacity is perhaps the most visible indicator of how far along technology has come. Just a decade ago, the highest capacity microSD card was 8GB. If you've been looking to store an insane amount of data on your phone, tablet, or other microSD-compatible device, SanDisk revealed a 400GB microSD card at IFA in Berlin.The card, which currently costs $250 on Amazon (frankly, I expected it to be higher), is A1-rated. This is the highest speed rating possible for microSD cards, higher than the UHS-1/V30 rating that is commonplace these days. SanDisk is promising up to 100MB/s read speeds, but the write speed is likely quite a bit lower (it's not explicitly stated).I honestly can't think of a single practical use for this card at the moment, unless you shoot a lot of 4K video and never offload them from your phone. You can buy the card from Amazon at the source link below, and SanDisk says the card will be available at more locations soon.Source: Amazon
