Why is this important to know? Because the new cards will be better able to handle the ever-increasing features and functions of new digital cameras. The method used to get past the previous limits on speed and storage is to add Peripheral Component Interconnect Express (PCIe) and Non-Volatile Memory Express (NVMe) to the SD interface. How did they do that? Same Form Factor, New Protocol The new protocol SD Express promises speeds of 985MB/s and maximum capacity of 128TB. If you need to hold more information or transfer it faster, one of the new card types seems to be the option.Ĭurrent SD write cards have peeked at 260MB/s and data storage at 2TB, with most being lower. SD cards, using the SD and SPI protocols designed in 1999 and enhanced several times since, can only hold so much data, and can only transfer that data on and off the card so fast. In the simplest terms, SD Express uses new software and physical design protocols within the same configuration of an SD card. But the SD card received a huge boost with the introduction of the new SD Express. It seemed that the SD design cards had reached their theoretical limits, that they had peaked in capabilities. However, SD is still the card of choice for some lower-end cameras, prosumer cameras, and consumer-level cameras.īut the thought that was on some photographers’ minds was whether the SD card could be improved for greater capacity and transfer speed. It looked as though the lowly SD (secure digital) card was not going to be used much anymore, at least not by professional-caliber cameras or other high-end cameras with huge MP count sensors. Well, a lot of photographers are intrigued by the XQD cards and a yet newer card in the same form factor with even greater capabilities – the CFexpress (CFE) card. Besides the big deal that was made about the camera’s one card slot, the amazing potential of the new card type’s capabilities were very exciting. With the introduction of Nikon’s Z6 and Z7 mirrorless cameras, photographers were introduced to the new XQD memory cards, if they didn’t already know about them. In the digital age, file formats and recording media are added to this list of things that change. Sandisk is just a poor match for this very specific job.Throughout the history of photography, new films, new processes, and new ways of doing things are an almost continual phenomenon. So I'm pretty sure this fixed it, and I ordered and installed the same card into my own device, and have so far not seen skipping on that either (only 2 hours of use so far tho). The Sandisk would last anywhere between 2 and 50 songs before skipping, the Evo went through over 500. (PS I also asked this in another community a few minutes ago, sorry if that's illegal on Reddit or whatever)Īfter some recommendations on here and elsewhere, I decided to pick up a Samsung Evo (red) 128gb micro SSD, and installed it into my friend's one, and after using it several hours I can say that it never once skipped like the Sandisk does, and I even spent a couple of hours skipping through shuffle tracks. So I'm curious if anyone in here can confirm this, and perhaps recommend any other micro SDs that don't do this skipping thing. The second I opted for the simpler iFlash board option with a micro SD in it.īoth exhibit a problem where they freeze up and skip songs every now and then, and after doing some reading I'm finding anecdotal evidence that SandDisk and iFlash just don't play nice and cause this skip. The first, I used an iFlash compact flash adapter and generic 50pin adapter with a micro SD in it. I've now modified two 4th gens, one with 256gb and one with 128gb for a friend.
