SanDisk 128GB Extreme PRO SDXC UHS-I Card – C10, U3, V30, 4K UHD, SD Card – SDSDXXY-128G-GN4IN

Seit paar Jahren nutze ich mit voller Zufriedenheit die 128GB Version der Sandisk Extreme pro mit 95MB/s. Aktuell gab es die 170MB/s Version deutlich günstiger. OK, fast doppelter Lesespeed, warum nicht. 4 Karten für meine GH5 bestellt und das Entsetzen folgte. Die Karten passen nicht mehr korrekt in den SD Card Schacht der GH5. Die Karten sind minimal dicker oder breiter wie bisher. Das führt dazu dass die Karten schon mit mehr Druck in den SD Schacht der GH5 müssen und jetzt wirds gefährlich. Der Schnappmechanismus in der Kamera funktioniert wegen den anderen Ausmaßen der Karten nicht mehr richtig. Das ist beim einsetzen schon problematisch, da dadurch das beschreiben der Karte behindert werde könnte aber richtig gefährlich wird es beim entfernen der Karte. Oder besser beim Versuch. Der Schnappmechanismus gibt die Karte nicht mehr zuverlässig frei! Wenn er es macht, “ploppt” die Karte aber nicht wie andere einfach ein Stück heraus, sondern bleibt stecken. Man bekommt sie nur mit spitzen Fingernägeln oder Pinzette heraus. Wenn der Schnappmechanismus des SD Card Schachtes aber klemmt, hat man einen Fall für das Panasonic Repair Center! Unfassbar was SANDISK hier verbockt hat. Ich habe bei Amazon als Verkäufer gekauft, also kein windiger Drittanbieter. Weil es könnten auch Fälschungen sein, aber der Aufdruck an dem man das erkennt scheint das nicht zu bestätigen oder die Fälscher haben sich “verbessert”. Selbst an meinem Notebook höre ich beim einsetzen und entfernen der Karte ein deutliches schleifen am SD Card Schacht und es ist schwergängiger. So muss ich vor dieser Karte leider dringend warnen! Auch die “neuen” 95MB/s Versionen haben dasselbe Problem.

I was super skeptical to buy this (I bought the 128gb). I read a lot about fake SD cards being sold online and the price sort of grabbed my eye and made me worry of that. I threw it in my camera held the shutter for 3 seconds. took 30 pictures and only had like a 2 second buffer at the end. Definitely a huge upgrade from the other SD card I was using. After wanting to stress test it some more to make sure it meets par with what specs are listed. I ran it through “h2testw” and it was writing to the card for 40minutes at an average of 75mbps. Which is lower than listed but I also have to consider that I’m using a cheap $20 card reader that never gave me great transfer speeds so I’m sure that it wasn’t the cards fault and more of me cheaping out on getting a card reader to transfer files. Recorded a bit of video with it and compared the file sizes to my older card and realized the my other card was throttling my video quality and not able to handle the mbps that my camera was capable of putting out. All and all I’m very impressed with the price and performance of the card.

I’ve used SanDisk cards for years and they’re reliable AF. Fast and durable too. I’ve always found the 64GB size is ideal for modern DSLRs (24MP and up) — a lot of images can be stored, but not so many that you’re risking all your “eggs in one basket”. Dollars per GB can be a little cheaper at the larger sizes, but unless you’re shooting ridiculous amounts of 4K video (and even then), it might be best to stick with smaller cards.

Don’t cheap out and buy lesser-brand cards. After all, memory cards are the most important component of your camera and the one thing that needs to be rock solid.

One minor drawback on these is the packaging. The outer cardboard is easy to open, but the plastic seal inside is a nightmare to open, even with sharp tools.

I received fake cards

Caution genuine Sandisk SDcard have grey lock tab, not yellow like those I received.

When the memory card arrived it wasn’t in the usual SanDisk cardboard packaging, it was in a simple clear and white plastic envelope. This got me wondering if it is a legitimate card so I contacted the manufacturer. They requested closeup front and back photos of the memory card so I emailed them. Their response was this is not an authentic SanDisk product and advised me to get my money refunded.
SanDisk makes a reliable product but if you are using a fake card it will fail at some point and you will lose your photos. Buy at your own risk.

I tested the card when it arrived today and the capacity is correct. However here are the read/writes speeds after repeated tests:

Warning: Only 60803 of 60874 MByte tested.
Test finished without errors.
You can now delete the test files *.h2w or verify them again.
Writing speed: 81.9 MByte/s
Reading speed: 89.1 MByte/s
H2testw v1.4

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???
