arguably one of the most impactful developments in storage has been the microSD card with capacities of hundreds of gigabytes on a card about the size of your fingernail they've enabled awesome storage flexibility in tons of small devices that even full scale home PCs 20 years ago couldn't dream of but in this age of say 2/3 and PCI Express drives it is clear that the bottleneck of most storage formats is still one that people want to overcome and that is speed and this is especially relevant to micro SD as these small memory cards are becoming increasingly popular as a more primary storage device such as in a netbook or a smartphone or Raspberry Pi well enter universal flash storage or ufs a new format that aims to ultimately replace micro sd and although they're both about the same size yeah physically and in terms of capacity right now ufs promises to be a heck of a lot quicker most mainstream microSD cards have sequential read and write speeds below 100 megabytes per second and even high-end UHS 2 cards have a theoretical cap of 312 megabytes per second one direction or 156 megabytes per second in full duplex with most cards being slower than that ufs on the other hand can perform sequential reads at up to 530 megabytes per second which essentially matches high-end SATA 3 SSDs write speeds will be as high as a hundred and seventy megabytes per second allowing for better performance when recording 4k video or taking large uncompressed photos things that are becoming more and more common as feature-rich smartphones decrease in price and become more widespread and if you're interested in using a ufs card for things other than just storing large files such as running mobile apps or using it instead of a hard drive in something like a book ufs also has vastly improved random performance which is usually expressed in IAP sir inputs and outputs per second which is the most important thing in some ways for everyday all purpose use something you can learn more about in this video so the fastest current-gen microsd cards can get a little over 3,000 i ops 4k random reads but you FS cards can do up to 40,000 read and 30,000 bright ions that's not quite as fast as a current mid-range SSD which might get around 70,000 I ops but that is still insanely fast for such a small card and several thousand times faster than your typical mechanical hard drive so not only do these increase speeds mean better performance they might also give us greater flexibility with regards to app storage options as many developers haven't allowed their apps to run directly off of microSD cards due to concerns about responsiveness and since devs might be more open to having their software run off of us fest cards you're not going to be as hamstrung by your phone's internal memory and you might even get well more value optimized choices for your next phone since manufacturers won't have to maintain SKUs with a bunch of different capacities inside you can just put in your own storage add in the significantly lower power consumption compared to microSD which will keep your battery powered up for longer especially if you're taking pictures or recording videos and ufs looks set to make our mobile gadgets even more useful than ever before though you might have to wait a bit to take advantage of it Samsung just announced you FS quite recently in the cards haven't quite hit the market yet not to mention that there aren't any readers for them however this might be good news for those looking to buy a Galaxy phone in the near future especially as Samsung has developed a slot that can accept both micro SD and u FS cards even though the two formats aren't electrically compatible but regardless of your device of choice keep an eye out for u FS card soon because nothing could be worse than your micro SD card depleting your battery while you're in the playing Pokemon go could anything be worse than that no it could not speaking of things they
