Designed for SD devices that can capture Full HD, 3D, and 4K video, as well as raw and burst photography, the 256GB Extreme PRO UHS-I SDXC Memory Card from SanDisk has a capacity of 64GB, is compatible with the UHS-I bus, and features a speed class rating of V30, which guarantees minimum write speeds of 30 MB/s. If your device does not support the V30 standard, this card also supports the U3 standard, which likewise guarantees minimum write speeds of 30 MB/s. Read speeds are supported up to 170 MB/s and write speeds max out at 90 MB/s. A built-in write-protect switch helps to safeguard against the accidental erasure of card data. While this card has been designed for cameras that are UHS-I/ V30/ U3 compatible, it may be used in devices that do not support UHS-I/ V30/ U3. However, bear in mind that this card will then default to your device's speed class and bus rating, such as UHS-I and U1, which supports minimum write speeds of 10 MB/s, or Class 10, which also supports minimum write speeds of 10 MB/s.

I am using Sandisk Imagemate® PRO card reader with the card. I tested the card reader and my computer with Pro Grade cards, and they achieve the advertised speed almost 200MB/s.
For many, the read speed may not be important then this is an absolutely fine card but if you need to transfer large files quickly (say 170MB/s or more) then you are better to look for another card such as Pro Grade.
FYI: When inserting an SD card into the card slot of an iMac, you have to deliberately push from the corner of the card closest to the outer edge of the iMac. If you don't insert the SD card as described, the system may not give write permissions.
I had to buy a real one from the shop, when compared. This card writing speed is at about 20mbs
Do not waste your money and do not buy from this seller
Just used it in my Olympus OMD EM5 MKII
Worked perfectly and image saving were fast better than my other card.
I have used Scandisk for many years and none of the cards have failed me till now.
Also you get free two year RescuePro software license key with the card which will help you recover corrupted or deleted files from the card .
Just beware that you won’t get 170mb/s write speeds. But I knew that going in, so I’m not upset at all. I’m quite happy with the price considering because a few years ago I paid more money for a smaller card.

I am aware it says "up to 170MB/s" however this is pretty far from it, isn't it? It even says the same thing on the card, it's not like it's a typo on the Amazon page. Why???
En revanche, cette nouvelle gamme de 170 Mo/s a exactement la même vitesse que l'anciennce gamme dite 95 Mo/s... Alors pourquoi avoir changé la dénomination. D'autant qu'en réalité les vitesses sont toujours plus basses.
GAMME 95 Mo/s
Ecriture réelle = 75-80 Mo/s
Lecture réelle = 90 Mo/s
GAMME 170 Mo/s
Ecriture réelle = 70-75 Mo/s
Lecture réelle = 90 Mo/s
Ärgere mich dass ich 2 Karten diesen Typs bestellt habe 😡😡😡
Meine Kamera GH5 zeichnet mit einer Datentatte von 400Mbit/s auf = 50MB/s daher habe ich mir diese Karten 2x gekauft !
Leider wird die Aufnahme nach 22sec gestopt mit der Abzeige:
„ Laufbildaufnahme der Kamera wurde aufgrund begrenzter Schreibgeschwindigkeit der Speicherkarte abgebrochen“
Was soll der Mist !!!! Nicht mal 50MB / s packt die Karte ! Was für eine Mogelpackung !!!! Finger weg !!!!
Karten gehen zurück! Will mein Geld wiederhaben!
