Nintendo Switch and Android phone enthusiasts, rejoice: SanDisk is letting you store more than ever.
SanDisk has unveiled its largest-ever microSD card, packing 400GB of storage onto a single unit. Larger microSD cards have already reached this capacity, but this level of storage in a microSD card has only been reached by Microdia in the past with a 512GB microSD card that cost $1000 in 2015.
The SanDisk UltraPLUS microSDXC card has some other tricks up its sleeve as well. The company is keen to point out that this new product conforms to the A1 storage standard, which is designed not just for so-called “sequential” writes – the sort of behaviour you get recording video and shooting photos in a predictable order – but also for random reads and writes. Random reads and writes are much more challenging and are a key component of using a microSD card as an app storage device on your phone or Nintendo Switch.
SanDisk is claiming 100MB/s read and write speeds, and the A1 standard promises performance no worse than 10MB/s.
Given games like Breath of the Wild take up over 13GB of space on a 32GB Nintendo Switch, a high-performance card is fairly crucial. And with more Android phones starting to work with so-called Adoptable Storage – where the microSD card is used in the same way as the phone’s internal memory – high-capacity, high-performance microSD cards are essential.
This announcement comes hot on the heels of SanDisk’s 256GB card, which currently costs around £150. The UltraPLUS 400GB will cost £225 in the UK and $250 in the US.
Don’t worry, though, this isn’t the limit of the technology. The SDXC standard supports capacities of up to 2TB. It’s just that nobody’s got there yet.
