[Amazon.ca] Silicon Power 128GB Micro SDXC Card, U3 V30 A1, $19

This card is going for $19 right now. It used to go for $18 which was a better price than anything else on the market. Then COVID and inflation hit, and its price went up to $24-25. Now its back down to $19. I often keep an eye on these cards and I think this is a good price for this kind of card if you’re ok with Silicon Power.

FYI this is U3 V30 card which means it guarantees a minimum write speed of 30 MB/s which is what you want for 4K direct writing. Its normal write speed can exceed that but it has this guaranteed minimum rating which is what you want from an SD card these days.

It also has an A1 rating which is a rating for Random Read performance. Its not as good as A2 ratings, but obviously better than cards that don’t have the A1 rating (older standard cards).

If you are looking for an SD card for dashcams and constant writing, I recommend that you buy high endurance cards and not these. They will give much more millage compared to the money you spend and are better for those applications.

Also pay attention to shipping price, as it may differ whether you order 1 or more. Also make sure you check which seller you are buying from. This post is regarding the sale from Silicon Power USA as the seller.

I was on the lookout for a good price for many months, and finally this dropped. I purchased 2.
