A little over a year after the unveiling of the first 512 GB microSDXC card, SanDisk introduced the first 1 TB card. Micron has one too.
the SanDisk Extreme MicroSDXC UHS-I Card should be available in April priced at $ 450 and supports playback speeds of up to 160 MB / s and write speeds of up to 90 MB / s.
the MicroSD card 1TB Micron c200, meanwhile, should be available in the second quarter of 2019 and supports playback speeds of up to 100 MB / s and read speeds of up to 95 MB / s.
These tiny storage cards have four times more storage capacity than my laptop … but it's much slower than the NVMe PCIe SSD on my laptop. But the SD association has covered us there too. The group has just introduced a new Standard MicroSD Express this will allow microSD cards to reach speeds up to 985 MB per second.
MicroSD Express uses the PCIe 3.1 interface and the NVMe 1.3 protocol to offer higher data transfer speeds. Cards using new technology should also consume less energy than existing microSD cards.
Of course, you will not be able to insert one of these new cards into your old phone and triple or quadruple your data read / write speeds. You will need a new hardware compatible with the new standard to take full advantage of the new faster cards.
But they are compatible with earlier versions. For example, if you have a camera and / or USB card reader that supports the MicroSD Express protocol and a phone that does not, you can still use the same card with all these devices. Some devices will be slower than others.
It's unclear when the first microSD Express cards or devices capable of reading will arrive – so if you're looking for news that you can use in MWC mode, you'll have to settle for the imminent arrival of 1TB microSD cards that cost more than a mid-range smartphone.
