On the face of it, the SanDisk Extreme Pro seems overpriced. This U3, V30, UHS-I card is significantly more expensive than the Samsung and Integral competition at most capacities, and when tested on our SanDisk ImageMate Pro card reader it wasn’t any faster, at least on sequential read and write speeds, which were 96MB/sec and 85.4MB/sec respectively. When looking for a MicroSD, it is essential to buy one that is just right for its intended purpose. This means that buying a card that’s not just large enough but also fast enough and not automatically the fastest or largest one out there. There are high capacity cards like UHS-II U3 that comes with a steep price but you will not always notice the benefits it offers.
The Speed Class indicates the minimum write speed of a memory card in MBps or megabytes per second. The four Speed Class are as follows:Hardware that supports microSDXC slots will not automatically support every size of card in this format. If you plan on using your microSD card with your PC say for moving files on and off, you need to make sure that your PC supports the file system that the card is formatted with. MicroSD cards can be placed inside a so-called passive adapters which allows them to be used in ports which are designed for larger storage cards. Most commonly, Micro SD cards can be placed inside SD adapters. This is useful for using a single card in multiple devices as well as using Micro SD cards in SD card readers. Surprisingly, it’s easy to end up falling into various traps such as terrible performance, overpaying or worst, the card not even working at all. There are two forms of memory cards, SD and microSD. SD cards are basically used in bigger devices such as video cams and digital cameras. They are also a bit larger than your average postage stamp. MicroSD on the other hand are used more in gadgets like tablets and smartphones. They are smaller than full sized SD cards. There’s also a third form, the MiniSD, but this was used widely as a transitional form factor in the mid-2000s before the popularity of MicroSD. Today MiniSD cards are rarely seen. What’s more, this card comes into its own on random read/write speed tests. Here, we saw the fastest performance we’ve seen from a microSD card, reaching speeds of over 12MB/sec. Other cards from Lexar, Kingston and Samsung are catching up, but this is still the speed king for app and game performance. Given that it’s only slightly more expensive than the basic Ultima Pro, that makes it one of the top options for smartphone or Switch use.
