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

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 74-76MBps16K ran from 76-78MBps32K ran from 76-80MBpsThey 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.

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

works great

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.

Good quality product, exactly as described in listing. Will purchase more in the future.

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!

Big fan of SanDisc, have been using for many years

The media could not be loaded. Fantastic deal. I remember when a 512mb card would cost $80. I use this card to run the operating system of my Raspberry Pi 4b. I run octopi on it which is a pretty intensive program. I use it for a live video feed and to send commands to my 3D printer while I'm away. It hasn't let me down yet!Highly recommend this little card. It is an absolute workhorse.
