I’ve often bought SanDisk cards because they are good value for money and very reliable. I can’t remember ever having a SanDisk card fail on me, and that is why I keep buying SanDisk.
However, don’t rely on the stated speed. As their fine print says, that is only if you use their proprietary card reader (“proprietary technology”). But my camera will only use the standard UHS-I interface, which has a maximum theoretical speed of 104MB/s (according to their literature). But that is not what you will get. That is only the theoretical top speed of the standard.
Using a little utility called H2TestW.exe to measure my card’s performance on my Windows 10 machine (128GB 140MB/s using a generic USB 3.0 card reader), the read speed I got was 72.8MB/s and, more importantly, the write speed I got was only 30.9MB/s. Not 140MB/s. This is far from the advertised speed, but it is sufficient for my purposes of storage of my photos when I am on holiday, so I am happy with it.
I ram similar tests using my Nikon D610 camera and got similar results. What I did was to place the card in my camera and set the camera to continuous high shooting rate, which can do 5 frames per second. I turned image review off so it wouldn’t interfere with the results. I then pressed the shutter release button and started a timer when the green light (card access light) came on. The camera soon filled its internal cache memory and the frame rate dropped to a crawl. I kept the shutter button pressed and kept on timing it. When about 30 seconds had elapsed, I released the shutter release button. When the green light finally went out, indicating all images had been written to the card, I stopped the timer. That took 41 secs. I then connected the card to the computer and there were 50 photos (RAW) with a combined size of 1120 MB. So, doing the maths, 1120 MB / 41 secs = 27.31MB/s.
So that is consistent with the results of the first test. Not the 140MB/s advertised, but to be fair, none of the cards I’ve got do what they advertise. Funny enough, I have another older 128GB Ultra card with an advertised speed of only 80MB/s which actually reads and writes at about 60MB/s! So these older 128GB Ultra cards are significantly faster the their latest versions – almost twice faster!
If you need speed, of all the cards I have, the SanDisk Extreme PRO 64GB 170MB/s cards are the fastest I tested, and they read and write at just over 70MB/s. However, those cards are more expensive. I use them for initially capturing of my images (day shooting) and then transfer them to my bigger, cheaper cards in the evening, when I get back to the hotel room, and then clear those ‘day cards’ for the next day’s shooting. This system works well with my Nikon D610 camera which has dual card slots and allows me to copy the images from one card to another. It also gives me redundancy (copy all images to two or more separate storage cards) in case of card failure.
So the speed of these cards is not as important to me, but I just accidentally discovered these two different ways to measure the speed of cards, and was surprised just how much slower the cards are to the advertised speed, which is all over the front of the cards. Presumably all their competitors are doing similar things.
Overall though, I am happy with SanDisk, so I am happy with my new cards. But one star off for this lack of speed. I hope you found this review helpful.
Sandisks have never let me down. Super performance for DLSR. Bargain price. You can blat it with JPGs as fast as your DSLR can spit them out. Bit of buffering if you are doing bursting RAWs too. Can’t vouch for 4K movies as not tried. For “normal” JPG work no problem. If RAW and burst is your thing then do rate+size calcs as you may need something that supports a higher bit rate (at much increased cost).
Does exactly as it should, had a few of these and all have worked well and for extended periods of time.
Vorteile:
Groe Speicherkapazitt: Mit 128 GB bietet diese Karte viel Platz fr Fotos, Videos und andere Dateien.
Schnelle Geschwindigkeit: Diese Karte hat eine maximale bertragungsgeschwindigkeit von 80 MB/s, was bedeutet, dass Dateien schnell auf die Karte geschrieben und von ihr gelesen werden knnen.
Kompatibilitt: Diese Karte ist mit vielen verschiedenen Gerten kompatibel, einschlielich kompakten Kameras, DSLRs und Action-Kameras.
Zuverlssigkeit: SanDisk ist eine renommierte Marke in der Welt der Speicherkarten und die Ultra SDXC UHS-I Karte ist bekannt fr ihre Zuverlssigkeit und Haltbarkeit.
Nachteile:
Nicht so schnell wie andere Karten: Obwohl die 80 MB/s bertragungsgeschwindigkeit schnell genug fr die meisten Anwendungen ist, gibt es schnellere Speicherkarten auf dem Markt.
Begrenzte Kapazitt: Fr professionelle Fotografen und Videofilmer, die groe Dateien aufnehmen, knnte die 128-GB-Kapazitt zu gering sein.
Nicht fr alle Kameras geeignet: Diese Karte ist speziell fr kompakte Kameras konzipiert und nicht alle DSLRs oder spiegellosen Kameras knnen sie vollstndig nutzen.
Warum ist die SanDisk Ultra SDXC UHS-I Speicherkarte mit 128 GB vor allem fr kompakte Kameras interessant?
Kompakte Kameras sind in der Regel nicht so leistungsfhig wie DSLRs oder spiegellose Kameras und haben oft begrenzte interne Speicherkapazitt. Daher bentigen sie eine Speicherkarte mit ausreichend Platz und schneller Geschwindigkeit. Die SanDisk Ultra SDXC UHS-I Speicherkarte mit 128 GB ist eine groartige Wahl fr kompakte Kameras, da sie gengend Speicherplatz bietet und schnell genug ist, um schnelle Serienaufnahmen und HD-Videoaufnahmen aufzunehmen. Darber hinaus ist die Karte auch mit anderen Gerten wie Tablets und Laptops kompatibel, so dass man leicht Fotos und Videos auf andere Gerte bertragen kann.
Bought for a digital camera, basically does what is says and price was good.
Very fast delivery
Good price and packed very well
Very happy with everything
Thanks Amazon x
What I love most about SD cards is that they’re transferable with zero-hassle between my PC and MacBook, and my camera, unlike USBs. SanDisk ones have never let me down.
Speedy sd card, haven’t used tech do can’t comment, i don’t trust cloud storage one bit now so i have these to store and use like a USB drive.
One odd thing when i put it on my PC the date on it was 2026, most likely a fault or glitch as it was brand new and blank but Cu X-Files music yet again…
.
good value for money, not the best out there but all i need it for is storing photos from a camera and its more than good enough for tha
