Six months ago, SanDisk unveiled the world's first 400GB microSD card and made me feel like god having so much data storage on the tip of my finger.
。

Now, at Mobile World Congress, the storage company's back to explode heads with a newer version that's more than 50 percent faster.。

The new "Extreme A2 microSD UHS-1 microSDXC" card's the same physical size and capacity as the old one, and it's red and gold instead of red and silver; however, it's no longer the world's largest microSD card anymore because that honor belongs to the 512GB card by Integral Memory -- but it's still hella fast.
。

SanDisk says the microSD card uses proprietary technology from its parent company Western Digital to achieve read speeds of up to 160MB/s and write speeds of up to 90MB/s. By comparison, Integral's 512GB microSD card only reads data at up to 90MB/s; write speeds are a vague "lower" according to the company's website.

A large amount of storage on a tiny-ass memory card is great for stashing all your data and media, but it's pointless if your devices are spending forever to read and write to them. 。

This microSD card is hella fast.。

Besides being extremely useful for transferring huge amounts of data in a jiffy, these doubled transfer speeds will be useful for photographers and video shooters who shoot lots of high-megapixel photos or 4K (or higher-resolution footage). Y'all know how slow memory cards can be to save large-sized RAW photos.
 。 Is a 400GB microSD card that's uber-fast nerdy and geeky AF? Hell yeah it is, but that's why we love it so much. Sure, storage isn't ever going to be a sexy thing, but this card -- 400 gigs of storage with even faster speed in the same physical dimensions as the original 32 。 megabyte 。

megabyte 。

• released in 2005 -- is what pure technology progress really looks.。

• And if you need a refresher on how much a 400GB microSD card can hold, here's a cheat sheet:。

• About 400,000 e-books (at an average size of 1MB per e-book)
  。

• About 200,000 photos (12-megapixel iPhone 7 photos at an average size of 2MB)。

• About 100,000 iTunes songs (at an average size of 4MB for an average 4-minute tune)。

About 88 Full HD movies from iTunes (at an average of 4.5GB per movie)。

About 16 Blu-Rays (at an average size of 25GB)。This super high-capacity and super fast card will cost you a pretty penny, though: $300.。
