Lexar announces the microSD A2 with the largest storage capacity in the world
The American manufacturer has launched a new model of microSD that combines compact size with a very high storage capacity and performance with apps that meet the needs of the A2 specification.
The new Lexar High-Performance 633x A2 512 GB is the only microSD of the newly announced microSD card family to boast the highest specifications in terms of Application Performance. The series of the American manufacturer consists of several models in denominations from 16 up to 512 GB, but only the top version of the range supports the class A2, where the others stop at the A1.
All cards use a UHS-I interface and are certified for readings at the maximum speed from 95 to 100 MB/s, and writes from 45 to 70 MB/s.
As for the video, there is support for the Video Spec Class 30. The microSD with this specification guarantee a minimum sequential write speed of 30 MB/s under any circumstances, thus offering the ability to record video even at resolutions higher, and at high frame rates.
According to the specifications the new Lexar microSD can be used in a temperature range from 0 to 70°C, also in terminals that are usually subjected to extreme environments (think of an action-cam). The ideal place to insert a new Lexar High-Performance 633x, remains the smartphone, due to support for the A1 or A2 classes.
The A1 standard is quite widespread in the latter period, the A2 has yet to spread. According to the specifications, a microSD A2 must execute 4000 IOPS and 2000 IOPS in, respectively, reading and writing, where the A1 required a speed of 1500 and 500 IOPS. The new models must also support functions such as command queuing (with a tail depth of at least 2, and a maximum of 32) to optimize random read performance. It should be noted that in order to exploit the function, the device must also be enabled.
The Lexar High-Performance 633x A2 512 GB microSD is the first to boast such a large storage capacity, coupled with the support of the Class A2, but it is not the first 512 GB. Other companies have launched their memory cards with 512 GB, such as Samsung with its Samsung Evo, which uses the UHS-I U3 interface but is not certified A2, or PNY, whose model is certified V10 but does not support any specification Application Performance. The price of the new Lexar model is not affordable, it will arrive in the US soon at $ 299.99.
