Sandisk Extreme SD Memory Card Review

Sandisk Extreme SD Memory Card ReviewThe Sandisk Extreme sit further down in the memory card performance spectrum compared to the different Sandisk cards. Where the Sandisk Extreme Plus saw the same read speeds as the Pro and only slightly slower write speeds, the Extreme will have even slower write speeds and slightly slower read speeds.

This doesn’t make Extreme a bad card, in fact the Sandisk Extreme cards are still great for many devices. A lot of entry-level cameras aren’t capable of producing very fast write speeds, so this makes the Sandisk Extreme one of the best sd memory cards for the price for those devices. So point and shoots, and a lot of Sony and Panasonic cameras.

Real World Memory Card Performance

Real world performance with the Sandisk Extreme is just average. Not great, but not terrible either. Slightly slower read speeds than the Extreme Plus and Pro cards and quite a bit slower write speeds as well. The card is still fine, a lot of cameras can hardly produce faster write speeds than what this card is capable of anyway, especially slower cameras designed more for consumers like a lot of the point and shoots, or even a lot of Sony cameras. Not that Sony cameras are designed just for consumers or anything, it’s just most of their cameras before 2018 had very slow bus speeds.
