" The packaging for this SD card makes some pretty bold claims about its speed and performance - 160MB/s reads and 120MB/s writes. I realize it says "up to" meaning that there factors that can cause the speeds to be slower - which is why I benchmarked this card with a tool that tests pretty much every read/write scenario and I ran the test using more than one card reader.
The benchmark results were identical to the performance of an EVO Select SD card - reads maxed out at around 90MB/s, and writes maxed out at 80MB/s. I would love to know under what circumstances Samsung managed to get the advertised speeds, because I couldn't even get close. Large files, smaller files, single threaded, multi-threaded, nothing made those numbers budge - not even enabling write-caching.
You may be able to pop this into a Mac or Windows computer, copy files to or from it and see higher numbers than that occasionally register in the status window, but those operating systems have a variety of little tricks they use to make the transfer seem like it's moving faster than it actually is. I guarantee you if you measure the actual time it took to transfer a given amount of data you're not going to get faster than the numbers in that benchmark.
I tested this at the same as an EVO Select card which costs about 30% less for the same capacity and the results were identical.
My advice is just go with the EVO - it's not as fast as advertised either, but it's way cheaper."
Seems like this is no different from Evo Select which is 25$. Another person says this has less available storage than EVO SELECT
