But, what about reliability? Even if your data is being shared at breakneck speeds across devices, it won’t do you any good if it’s not secure or if it gets corrupted often. OK, so it’s clear as daylight by now that flash drives take the cake when it comes to data transfer speed. Compared to SD cards, I’m sure you’ll be impressed by what you see here. Whereas even high-end UHS-II cards max out at 312MB/s, standard USB 2.0 drives just start out at 480MB/s! Now, let’s look at the data chart. Flash Driveįlash drives are typically much faster than SD cards.
InterfaceĪs you can see, even in some of the best cards with advanced interfaces, the data speed is rather mediocre. One of them is SDIO (Input/Output), which isn’t related to data, but here are the other ones.įirst comes SD Standard Capacity cards, which can usually hold around 2GB of data then we have SD High Capacity ones which go a notch higher up to 32GB beating that out of the park are SD eXtended Capacity cards, holding up to 2TB then the SD Ultra Capacity ones go up to a mind-boggling 128TB! Here are their respective data speeds. Just like The Godfather, there are five families of SD cards, each with their own storage capacity limits. Similar to flash drives, SD cards come in many shapes and sizes. So, let’s compare SD cards with flash drives in the context of data transfer speed. We all are dealing with large files and need to manage multiple devices at once. These days, data transfer speed has become very important.
