If you store apps and photos on your microSD card (what else would you use it for?), then a higher-speed microSD card will save photos faster, improve data transfer speeds when moving files between devices, and open apps stored on your microSD card more quickly. The most important question is whether picking one microSD card over another will improve performance on your phone, to which the short answer is 'yes'. Will a better microSD card speed up my phone? In theory, UHS cards can reach data transfer speeds of up to 312 MB/s, but this isn't realistic. As such, UHS will make little difference to your microSD card speed at this point. Since 2009, certain microSD cards are also UHS-1 or UHS-3-compatible. While in theory, UHS cards can reach data transfer speeds of up to 312 MB/s, you are realistically only likely to attain the minimum transfer speeds listed below, because no smartphone currently supports the UHS standard. One such card is the SanDisk Extreme Pro, which can be picked up for $33 at. However, top-quality cards can run much faster than this, with some of the best ones out there clocking read speeds up to 95 MB/s. The 'Class' number directly reflects the minimum write speed of the card. Suddenly it's not that complicated, right? SDHC and SDXC speed classes Class So a Class 2 card reads and writes data at 2 MB/s, while a Class 10 card does so at 10 MB/s. While these numbers may mean nothing to you (and leave you wondering what happened to the other numbers up to 10), they do in fact simply reflect the minimum rates at which these cards sustain data transfers. MicroSD cards come in several different classes - Class 2, 4, 6 and 10. What does 'class' mean on a microSD card? Make sure you know the different types of microSD cards before purchasing. Most SDXC cards go up to 128 GB, but in March 2015, Sandisk revealed the world's first 200 GB microSD SDXC card. Many lower-end devices don't support SDXC microSD cards, so it's crucial that you check your phone's compatibility before buying one. SDHC (Secure Digital High Capacity) stores up to 32 GB of data, while SDXC (Secure Digital Extended Capacity) handles 64 GB and above.
When buying a microSD card, you'll notice that it's either a micro SDXC or SDHC card. The difference between these two microSD formats is simply the amount of data they can store. What's the difference between SDHC and micro SDXC? If you want a phone that supports microSD take a look at the phones linked below.įirstly, make sure your device supports microSD cards. If there is no microSD slot, well, you can't use a microSD card.

If you need to, consult your phone's manual to open the device (or to find whether there is a microSD slot). You can inspect your device and see whether there is a microSD slot. And though from our perspective this seems ridiculous, we need to ensure our device has a microSD card slot. Unfortunately, as we mentioned above, many smartphones don't have microSD slots and instead claim that the on-board internal storage is sufficient. Firstly, make sure your device supports microSD cards
