SD Express storage has seen a surge in interest recently, with us reporting last week that MicroSD Express cards are now selling out in Japan in preparation for the Nintendo Switch 2 console launch in March.
The advantage of SD Express storage is that it is seen to come with fast data transfer and read rates, and also supports larger storage sizes. Recently, ADATA has introduced their first SD Express offering, the ADATA Premier Extreme SD 8.0 which comes with the SD Express 8.0 standard.
In theory, cards with the SD Express 8.0 standard certification come with a data read rate of 4GB/s, but with ADATA's offering, they say that their SD Express cards are capable of showing data read rates of 1.6GB/s and data write rates of 1.2GB/s.
However, these data read and write speeds are only seen to be possible for a short period of time, and since this SD Express card still features a U30 and V30 rating, it still only comes with a sustained data transfer rate of 30MB/s.
If you are interested in getting an SD or MicroSD Express card that has a higher sustained data transfer rate, you will want to look for a card that has an “E” rating with a number behind it. For example, an SD Express card with an E150 rating means that the storage has a data transfer rate of 150MB/s.
It is expected that ADATA will show more details about their SD Express storage at the Computex Taipei event which will take place at the end of May.
