SanDisk Announces a 400 GB MicroSD Card

SanDisk (Western Digital) has announced a 400 GB MicroSD card for $250:

In 2015, SanDisk released the world's first 200GB microSDXC storage media using TLC flash technology. Today the company announced a successor, the Ultra MicroSDXC UHS-I, which doubles capacity to a massive 400GB housed within a card roughly the size of your finger nail.

This form factor is now the de facto standard for several classes of devices that span a wide range of product types. Most modern cell phones and tablets have standardized on microSD, and the technology has also penetrated other devices, such as drones and game consoles.

This new 400GB model can hold up to 40 hours of Full HD video and has a transfer speed of up to 100 MBps. That comes out to transferring up to 1,200 photos per minute. The card also meets the A1 App Performance Class specification built by the SD Association to ensure high random performance. The specification insists that products carrying the logo can meet or exceed 1,500 random read IOPS and 500 random write IOPS for quick loading of mobile optimized applications.

Time to update your sneakernet bandwidth calculations with this and a 787 Dreamliner.

    I am in the industry and the manufacturing details are why I'm reading the article. Unfortunately there isn't an announcement how they made the chip, but speculation is that Toshiba made it with their new quad-level cell memory.

    The obvious question is if Western Digital just released a product with quad-level cell (QLC) memory technology. The press release leads us to believe so. because other companies have hinted that QLC will make an appearance in limited form before the end of the year, and Toshiba demonstrated working QLC at Flash Memory Summit with a massive 768Gbit die capacity.

    It could still be TLC since TLC is being used at 768 Gb AFAIK:

    Toshiba/Sandisk have also 768 Gbit TLC 3D BiCS on their road map for late 2017 and a 1Tbit chip for 2018.

    QLC capacity is only a 33% increase over TLC of the same density so it's not impossible to get to 1 Tb or higher with TLC, by just going to 96 layers or something like that.
