SanDisk is launching a 512 gigabyte SD card. It’s initially going to be targeted at professional camera crews shooting in high resolutions.

The new card will cost an eyewatering $800. That said, as PC Pro points out, SanDisk started selling a 512 megabyte card back in 2003 for $170. Byte for byte, that makes the new model more than 200 times cheaper.

Even disregarding the capacity, the new Extreme PRO SDXC UHS-I card isn’t an ordinary consumer model. It’s designed to operate in temperatures between minus 25 and 85 Celsius and is described as waterproof, shockproof and safe to go through airport security scanners.

SanDisk chose to launch the card at the International Broadcasting Convention and made clear it was targeting the market for recording in high resolution formats such as 4K. It’s also pitching the card at users of high-speed burst mode photography. The card supports UHS Speed Class 3, meaning it can write at the 30 MB/s needed for recording 4K video. (The card’s write speed is actually listed at 90 MB/s.)

The BBC notes a typical 4K recording would take up around 5GB of storage per minute, meaning the new card would be enough for around an hour and forty minutes recording. Geek.com puts in at four hours, though both note that it depends on compression settings.

While it’s going to be a good few years before the price tumbles enough to make it a consumer product, the card is probably bad news for people who get irritated by excessive camcorder use by tourists. With a standard HD capacity in the 24 to 30 hour range, it’ll likely only be battery life that will make them put the camera down.

This isn’t the end, either. Several reports cite unnamed “experts” as saying SD cards will eventually top out at 2TB.
