So far the largest capacity we can find in market is 1TB MicroSDXC card, the loading space will not be limited by this tiny body, therefore many devices are leaving one slot for bulk MicroSD card, it is one powerful and useful accessory.
So if you need to distinguish MicroSD from Standard SD Card, the easy way is to know from the size. Moreover the device they worked is also different, as we mentioned previously, we can know their difference by eyes. There is one rule we can follow, smaller device normally go for bulk MicroSD but bigger equipment loves Standard SD Card.
MicroSD Memory card is for storing data, as if the device requests data center, then MicroSD will be an option.
We can do classify on the device as follow.
As MicroSD card is removeable, many devices will design MicroSD slot and turn it to be the data center.
Micro SD is basically classified into three types. There are Micro SD Card, SDHC Card and SDXC Card. This is the fundamental define for the capacity of the card; it is ranging from low capacity to high one. As the name suggests that SD card represents the smallest space from 128mb to 2GB, SDHC stands for SD high capacity and SDXC is SD extended capacity. The capacity range for micro sd memory cards is respectively 128mb 256mb 512mb 1gb 2GB, 4GB to 32GB and 32GB 64gb 128gb 512gb 1TB 2TB micro sd memory card.
When choosing cheap micro sd cards for the devices we must pay attention to the capability of the devices, as there will be max capacity they can support. E.g. some phones only can work with max capacity at 32GB, but some can support 256GB. The tips for this part you can refer to the below guide.
The fast is the best. This standard is not working with memory cards. As bulk micro sd is one kind of accessory, the main task for it is to serve well for the electronic devices that use cards for loading storage. Therefore, the devices will decide the best speed, as some gadgets are designed with slower performance; the device will fail if we use too fast cards. Consequently we should know the speed of it by overall details.
There are many parameters related to the speed. The first one is class, it tells the writing speed, and in other words, it is the speed of copying data to the pc or devices. The info of class is obvious to mark out the writing speed micro sd card class4 class6 class10. Class 4 means the writing speed hits 4MB/S, Class 6 is 6MB/S and Class 10 is 10MB/S. These measurable factors only indicate the writing speed and no information of reading one. Besides it, UHS (ultra high speed) is another indication for writing speed. There is two types UHS, UHS-1 represents the writing speed at 10MB/S, and UHS-3 is 30MB/s by write. The common thing between UHS and Class is showing the data of writing speed, however, UHS also points out the reading speed. Although there is no specific number describing, the average reading speed will be from 50MB/S to 100MB/s.
Along with the development of science and technology, more and more electronic gadgets support 1080p and 4k video. Therefore, there is new parameter released. It is called video speed class and abbreviated by V10, V30, V60 and V90; these measured numbers are connected to writing speed but are minimum sequential write speed not max one. It means the minimum writing speed of V10, V30, V60 and V90 is individually 10MB/S, 30MB/S, 60MB/S and 90MB/S. The card under this standard is usually for high-end and industrial products, as only products in high performance will ask for such high writing speed.
Why the nomenclature on the cards all concerning with writing speed? Any specification will tell the read one? Of course, it is positive answer for these questions. The latest standard for Micro SD card is version 5.1, there is one new specification for the speed of running apps, it is A1 and A2. It marks the minimum writing and reading speed based on IOPS.
A1: Random Read input-output access per second of 1500, write IOPS of 1500
A2: Random Read input-output access per second of 4000, write IOPS of 2000
Above brief introduction of speed will lighten up the ideas of ordering cards. There is one simple tip to follow, and the list below will guide you to choose the right cards for your products.
Class 4/6: low-end phones, MP3, Mp4, Bluetooth speaker, electronic piano, baby monitor and the other gadgets supporting slow version.
Class 10/UHS-1: high-end Phones, camera, dashcam, GPS, Raspberry Pi, PlayStation, tablets and any electronic devices supporting SDHC.
UHS-3/V60/V90: Drone, industrial equipment, 4K sport camera, smartphones, and any 4K devices.
In fact, the popular sources in market are still class and UHS version, as the cost of them is more acceptable, also the capacity of them is mainstream. If you buy memory card the cost will be the first priority in addition to the quality; class and UHS version already can meet the speed requests, then there is no necessary to take expensive cards with UHS-3 or V60/90.
