Wondering what the difference is between UHS-I and UHS-II with SD and microSD cards and which you should get for your camera? Here’s an explanation. HomePhotography GearMemory CardsUHS-I vs UHS-II on microSD & SD CardsIf you’ve looked at buying an SD or microSD card lately, you might have run into some new codes: specifically, UHS-II.It refers to something called ultra high-speed bus, which in turn refers to the interface between the card and the device. So far, there is UHS-I and UHS-II. There is a specification of UHS-III, but I’ve not seen any cards actually turn up using that yet.UHS-II is the newer, and potentially faster, system but adoption is still not widespread. And a UHS-II isn’t necessarily guaranteed to be faster than every UHS-I card in practice. While it wasn’t always true initially, the current fastest SD cards are UHS-II (when used with a UHS-II compatible host, that is).CompatibilityThe UHS-I and UHS-II specifications are designed to be backward compatible. That means that you can use a UHS-II card in a device that’s compatible with UHS-I and vice versa. But if you do so, you’ll be limited to the lower spec, in this case UHS-I. That is the general intention, at least. But it gets a little more complicated, because there are different implementations of UHS-I that have different speeds. Some cards fall back to a slower UHS-I spec; better cards fall back gracefully to a UHS-I spec known as SDR104. Unfortunately, that particular part of the card’s capabilities is rarely specified in either the packaging or the technical specs.But in many cases, it frankly doesn’t matter which you get. But that’s simply because the cameras and devices that can take full advantage of UHS-II are only just starting to become available.And some that are UHS-II compatible can be a bit quirky. For instance, the FujiFilm X-Pro 2 camera has two SD slots. But only one uses UHS-II. So if you put a UHS-II SD card in the slot that has the UHS-I interface, you’ll be limited to UHS-I speeds.But if you have a device that does use the UHS-II interface–and the technical specs or instruction manual will say so if it does–then there’s a good chance you’ll get better performance out of a UHS-II card.One common device where this can become an issue is with memory card readers. Most of the card readers currently available support UHS-I cards. UHS-II cards will work, but they’ll be limited to UHS-I speeds. There are some card readers that do support UHS-II, such as the Lexar SR2 reader or the SanDisk Extreme Pro reader, but you can’t assume that every card reader does.How to Tell the Difference Between UHS-I and UHS-IIThere are two

Sebaiknya Anda mengecek kapasitas angka yang tertera pada produk.Tentukan UHS speed class dan bus interface berdasarkan kebutuhan Anda dalam menggunakan SD cardUHS adalah standar kecepatan tulis atau write pada SD card. Sementara itu, bus interface mengacu pada cara data ditransfer antara kartu SD dan perangkat. Pada SD card, UHS speed class diwakili simbol huruf “U” dengan angka 1 atau 3 di dalamnya. Sementara itu, bus interface ditunjukkan dengan simbol I atau II. Bus interface biasanya bersinergi dengan UHS speed class.UHS-I U1: Cukup untuk fotografi sederhana dan penyimpanan dataPakarUHS-I U1 atau UHS speed class 1 adalah SD card paling standar saat ini. Spesifikasinya sudah cukup untuk fotografer pemula atau kebutuhan menyimpan file saja.Untuk pemula dalam bidang fotografi, SD card UHS-I U1 sudah memadai. Memory card kamera dengan kecepatan tulis minimum 10 MB/s cukup untuk pengguna kamera entry level. Pengguna tipe ini biasanya hanya akan mengambil gambar dengan teknik sederhana. SD card ini juga cocok untuk merekam video 1080p yang biasanya merupakan resolusi pada kamera entry-level. SD card U1 biasanya lebih terjangkau dibandingkan SD card UHS-U3. Memory card kamera ini bisa menjadi pilihan untuk Anda yang memiliki anggaran terbatas dan tidak butuh kecepatan lebih tinggi. Pada umumnya, SD card ini sudah cocok untuk kebutuhan penggunaan sehari-hari ataupun penggunaan kamera yang basic.UHS-I U3: Mampu meningkatkan kemampuan continous shootPakarSD card UHS-I U3 atau UHS speed class 3 memiliki kecepatan write yang lebih tinggi. Dengan begitu, SD card dapat menangani task berat dengan lebih baik, seperti continuous shoot dan perekaman dalam resolusi 4K.Jika Anda perlu mengabadikan momen yang cepat, SD card UHS-I U3 bisa menjadi pilihan yang tepat. Saat continuous shoot atau pemotretan beberapa frame sekaligus, banyak gambar akan ditulis ke SD card dengan cepat. Karena itu, Anda membutuhkan SD card UHS-I U3 dengan kecepatan tulis minimum 30 MB/s.Kecepatan write yang lebih tinggi akan mengurangi waktu tunggu antar-pemotretan sehingga Anda tidak akan melewatkan momen penting. Perlu diketahui bahwa pada perekaman 4K, ada risiko buffering, kehilangan frame, atau video yang terhenti. Keunggulan lain dari tipe ini adalah minim risiko lag atau kehilangan frame saat merekam video beresolusi tinggi, seperti 4K. UHS-II U3: Lebih cepat untuk kamera canggihPakarJika kamera Anda mendukung, SD card UHS-II U3 dapat diutamakan. SD card ini memiliki performa continuous shooting yang bahkan lebih cepat dari UHS-I U3.SD card dengan bus interface UHS-II biasanya juga memiliki spesifikasi UHS speed class 3. Kartu memori kamera ini menawarkan kemampuan yang lebih tinggi dari UHS-I. Berikut beberapa

Ways to tell the difference. The first is obvious: look at the label or packaging. They’ll have either UHS-I or UHS-II, or sometimes just I or II. Technically, it should be Roman numerals, but you’ll sometimes see it incorrectly written as a number 1, like UHS-1.You can also tell them apart by looking at the cards themselves. UHS-I cards have a single row of pins on the back. UHS-II cards have two rows. In this example, both of these are SanDisk Extreme Pro cards, just different generations.At left, with the single row of contacts, is the UHS-I card. At right is the UHS-II card. David Coleman / Have Camera Will TravelU1 vs U3 vs V30 vs V60 vs V90The UHS-II code isn’t the only new code you’ll see on some microSD and SD cards. There’s also a new code that relates to suitability for recording high-resolution video. U1 and U3 have been around for a while; the new addition is V30.All of these are speed classes aimed at recording high-resolution video. And they’re a separate designation from the UHS-I vs UHS-II one. I have more information on microSD speed classes here.Memory Card ToolsHere are a few other related tools I’ve put together that can be useful when working with memory cards and data rates. Converting Mbps to MB/s & X Speed Rating to MB/sAnother related and common calculation that often needs to be done when working with memory cards is converting the convention for measuring video bitrate (Mbps, Mb/s, or megabits per second) to the convention for measuring the speed of memory cards (MBps, MB/s, or megabytes per second). So I’ve put together a simple calculator for that separately. You can find it here: Convert Megabits Per Second to Megabytes Per Second CalculatorConvert Memory Card X Speed Rating to MB/sMemory Card Size CalculatorsIf you’re trying to figure out what size memory card to buy, it can be useful to know how much video footage from the camera you can fit on a card.

Fastest SD Card Speed Tests.

Our early impressions are that the Z6III matches the Canon and Sony in terms of autofocus tracking performance and usability, wheres the Panasonic lags a little and the Z6 II feels like it's left significantly behind.Likewise the new Nikon and the Canon stand ahead in terms of video performance, as they offer faster video capture with less rolling shutter, especially compared with the rather slow Sony. We'll need to shoot the Nikon more to know whether it can outdo the Canon's video AF, which isn't the most dependable.The stills stabilization figures do nothing to convey the smoothness of video stabilization, either, with the Panasonic doing particularly well in this regard. Increasingly, choice and availability of lenses will be the critical deciding factor for a lot of people.Body and handlingThe Z6III looks, at first glance, a lot like the existing Z6 and Z7 models, with a familiar low-height camera with significant hand grip
