Extreme PRO microSDHC Memory Card Plus SD Adapter up to 100 MB/s, Class 10, U3, V30, A1 - 32GB SDSQXCG-032G

There are many fake memory cards out there and it's really difficult to put your finger on a fake or the real deal. I purchased a few standard Sandisk MicroSD cards for my Raspberry Pi(s) and found that they tend to fail after a while, and eventually to stop working. So I decided to try an Extreme Pro one, and chose to purchase it directly from Amazon where I trust to buy. The packaging and the card I got look legit, and up until now it works without any problem. I really hope that it will last more than the standard ones I had.

I bought this microSD card to be used for my newly purchased Raspberry Pi 4B. It is a great 32 GB SD card to have Raspbian Linux to boot off and to be used as the the Raspberry Pi "hard drive". I can't even tell that the Raspberry Pi is booting off an SD card and not off a real SSD; it's that fast. In fact, I liked this microSD card so much that I bought another one to make a backup of my Raspberry Pi system. Before I modify anything in my Raspberry Pi (like changing the desktop environment, display manager, etc.), I first make a backup of the SD card onto another one, using the Raspbery Pi's "SD Card Copier" utility. If something goes wrong, I just swap out the SD cards and I'm back in business. You really can't go wrong with this SD card. I also recommend the X-Kim Dual Slot USB A & USB C card reader to use with this microSD card. The card reader can be used with the Raspberry Pi (using the USB A port) as well as with the new Macbook Air and Pro that only have USB-C ports. Amazon was great shipping the SD cards and the X-Kim SD card reader to me. Perfect products and perfect service!

I tested these since some have cache to burst in the beginning and slow down after a few gigs. Others run the speed up and down. I looked around for a good price compared to speed and reviews and these chips came out on top for me. 1) I formatted them Fat32 with 8, 16 and 32K blocks. 2) I ran large block tests since that would fill up the burst cache if there was any. 3) I always copied new content so my computer wouldn't have the files in Cache. 4) My dataset was movies since they could not be compressed and it was large block streaming. 8K ran from 74-76MBps 16K ran from 76-78MBps 32K ran from 76-80MBps They were all pretty consistent. Since I was using them for my Pi OS this really told me the overall performance is between 74-80MBps and it was consistent. Not "Bursty" at all. If using them for storage I would go with the 8K blocks to get more small files on them. For movies 32K is awesome. Bottom line. I was very impressed by the speed compared to the cost. Great chip and I now have a new "Go To" in my tools.

Great sd card. These are the best on the market. I don't need to talk then up. Will order a nother when needed.

Its difficult to find a good Class 10 U3 with the smaller capacities that are supported by certain products. This card made it through Texas winters and summers in an outdoor trail camera.

Compré esta SanDisk Extreme PRO para usarla con mi cámara Mini Evo y funciona de maravilla. La velocidad de escritura es excelente y las fotos se guardan al instante, sin errores ni demoras. Ideal para quienes tomamos muchas fotos o creamos contenido para redes sociales. Además, se nota la calidad del producto: rápida, confiable y con buena capacidad. Si usas una Mini Evo o una cámara similar, esta memoria es una excelente elección. Muy recomendable 👌

It works for Nintendo 3ds and Nintendo 3ds xl.

I bought this card because it the fastest card with the features I want at the right price. If on paper wasn't enough, I went to several benchmark sites that compare SD cards. This card consistently ranked as the lowest priced upper-echelon performer w/o going to a higher capacity. Let's face it, the faster cards are for high-resolution cameras. Anyway, there's a VISIBLE difference in Rasberry Pi on SD. I was spoiled by BerryBoot so I didn't think I needed to invest any more in SD cards. Then I got a new 8gb Pi that broke BerryBoot. Back to SD. Since one can't multi-boot an SD, one is forced to install one OS per card. This card is the default RPi SD but I use Kingston Canvas SDs as a backup. Cheaper but no slouch. First I had different OSs and bits. Then I was like "Wayment!" I put the same OS on the two cards. You can see the difference. Read/write speeds, specs, "tough-built," warranty, AND price. This is the Rasberry Pi 32G SD card you are looking for. Buy this now.
