Extreme SDXC 128GB SanDisk launches 128GB SDXC card and 64GB iNAND Ultra

When it comes to flash memory there's no doubt that SanDisk is one of the major players, especially as the company has developed or at least co-developed most of the flash memory card standards in use today. Now the company has gone and announced what it claims is the world's fastest 128GB SDXC card, as well as a new iNAND Ultra chip using 19nm flash memory.

SanDisk is something of a household name and often a first choice for many when they're shopping memory cards for their digital cameras, camcorders and phones. However, SanDisk's latest additions aren't likely to end up in your average consumer device, as they're simply outrageously expensive.  What we're looking at is a 64 and a 128GB SanDisk Extreme SDXC card that supports the Ultra High Speed or UHS-I standard which is rated at speeds of up to 50 or 104MB/s, but SanDisk's new cards falls a little bit short here with a read and write speed of 45MB/s.

It doesn't make the new cards the fastest SD cards out there either as even SanDisk itself has faster models, but there are only so many 64 and 128GB, hence the world's fastest claim. The cards are still plenty fast to handle high bit-rate 1080p video or 24Megapixel RAW images from the latest DSLR's, so this shouldn't be too much of an issue and the card is labelled as being able to store 32h of video. However, with an asking price of US$199.99 (S$258) and US$399.99 (S$516) respectively, they're anything but affordable.

As for SanDisk's new iNAND Ultra chip, we're looking at a reasonably small 11.5x13mm piece of flash memory that can hold 8GB all the way up to 64GB. As we mentioned it's using 19nm flash of the MLC kind and it sports an eMMC interface. Sequential read speeds are rated at up to 80MB/s, but sadly the write speed is a mere 20MB/s. Still, it's comparable or better than the NAND flash you'll find in many smartphones and when it comes to copying files the USB 2.0 interface is still a limiting factor as far as the write speed is concerned. As this is a product intended for devices makers, SanDisk didn't offer any pricing details, but volume production will take place in Q2, so in other words it'll be at least another quarter after that until it starts appearing in devices.
