If your mobile has a slot for microSD cards it’s easy enough to buy one, put it on, and enjoy a lot more storage. Most mid-range devices have these slots and the price of the cards it has diminished quite a bit over the years.

The problem is not in how the content is stored or if these cards can damage your terminal, something that we have already confirmed will not happen. The key issue with MicroSD cards is in the speed of reading and writing of the same. Son much slower than internal storage of your device.

It is easy for your current device to have a UFS 2.0 storage, which, depending on the amount of GB you can read at a speed of about 1,000 Mbps and write at more than 200 Mbps. These speeds are much lower on MicroSD cards that you can buy on Amazon or any store.

We have chosen one MicroSD Sandisk 64 GB of the most advanced of the moment and with a decent price: € 14 for 64 GB. The maximum speed of reading is 160 Mbps and reading is 90 Mbps. You see the difference?

All the actions that your device goes through reading or writing to the MicroSD card will take longer than doing the same on internal storage. View a photo from the gallery, open an application, move a file … Everything will be much slower when you go through the MicroSD!

In the example that we have given you, a current card and one of the best on the market has been used as a reference, but if you use one that has been around your house for several years, this experience could be even worse. Your mobile could suffer a slowdown very severe by simply inserting a MicroSD card and starting to use it.

Think carefully if you are going to need more storage

This “problem” with microSD cards and the speed can be easily solved when buying your terminal. Are you going to buy the version with 64 or 128 GB? Think very well if in the future you are going to need more storage, Well, buying a version with more GB will cost less than 50 euros / dollars, while buying the version with less GB could mean that in the future you have to spend 20 or 30 euros / dollars to have double the storage.
