I have purchased a lot of microSD cards through out the years. Every year they get faster and more storage. I just purchased a new 128GB card to use for CoreELEC testing, so thought I would give my thoughts on which one to purchase. I do a lot of researching since all I have is time.
I use H2testw v1.4 on my Windows PC to run speed test. I keep track of the speeds of my cards, so thought I would post the results here, in case someone is looking to upgrade their card.
