Sony's upcoming SF-G series of SD cards will be available this spring, the company announced today. When that time comes, Sony said they "will be the world's fastest SD cards." Boasting a maximum write speed of 299 MB/s, that claim is right on point.


The cards (available in 32GB, 64GB, and 128GB sizes) also have a slightly higher top read speed of 300 MB/s. Speed is a priority, so the cards also support the UHS-II interface, which adds a second row of connecting pins to the card for increased transfer rates on compatible hardware. More than any card before it, the SF-G series will be able to handle quick-shooting cameras smoothly, as well as capturing 4K video and other technically demanding uses.

To fully take advantage of the tremendous speed, Sony also revealed it will offer a specialized card reader so users can quickly transfer files to and from their computers. The SF-G series will take good care of your files, too. In addition to being compatible with Sony's file rescue software, these SD's are also waterproof, temperature resistant, shockproof and X-Ray proof.

For comparison, B&H Photo Video says that two of the fastest SD card lines out there today, SanDisk's Extreme PRO UHS-II series and Lexar's Professional 2000x UHS-II series, can achieve read speeds of 300 MB/s and write speeds of 260 MB/s. For the more casual user, Amazon's best-selling card, the 32GB SanDisk Ultra Class 10 SDHC UHS-I, tops out at 80 MB/s for read and write speeds.

Sony has yet to announce the pricing for these cards, but the 32GB version of the aforementioned SanDisk card sells for about $60. The SF-G cards are technically superior, though, so expect them to retail for a bit more than that.


Now you can download Netflix shows to your Android's SD card


Netflix rolled out a new feature in its latest update for the Android operating system on Tuesday: the ability to download shows to your device's SD card. When saving a show for offline viewing, users will now be prompted to choose a download location, either Device Storage or the SD card.

This could offer an interesting new way for users to consume their video content. Theoretically, it could allow users to download far more episodes and films than they would otherwise and build up huge catalogs of offline shows. However, as a Netflix rep told Engadget, "You can download content to multiple SD cards. However, there are limits to how many simultaneous downloads a member can download at one time, along with limits on how long a download will remain accessible. This ensures that the feature is being used for its intended purpose." Additionally, users won't be able to share SD cards amongst multiple devices as the content on the card will only play on the device that it was originally downloaded with, the rep explained.
