The Samsung Pro Endurance 128 GB MicroSD is rated to record a massive 43,800 hours of video footage
MicroSD cards aren’t all created equal. The newly announced Samsung Pro Endurance is targeted towards the constant write scenarios that cards in dashcams or surveillance cameras are subjected to. They are also waterproof (IPX7), temperature proof (-25oC to 85oC operating range; -40oC to 85oC non-operating), X-ray proof (up to airport x-ray machines), and magnetic proof (up to MRI levels).
These Pro Endurance cards come in 32 GB, 64 GB, and 128 GB capacities and as usual, the higher capacity cards have higher endurance ratings since each sector must be written more frequently on the smaller cards for the same amount of data. This is because the 32 GB card fills four times for every time the 128 GB card does, or twice for the 64 GB card. The endurance ratings in capacity order are 17,520 hours, 26,280 hours, and 43,800 hours and the warranties match these with two, three, and five years. Those ratings were obtained based on 1920 x 1080 FullHD video at 26 Mbps (3.25 MB/s). These new cards are UHS-I and provide 100 MB/s sequential read and 30 MB/s sequential write.
For comparison, Sandisk’s Ultra Endurance MicroSD cards are rated for a much lower 5,000 hours and 10,000 hours on the 32 GB and 64 GB models using the same video resolution and bitrate. The rated sequential read and write speeds are also slower at 20 MB/s for both.
The Samsung Pro Endurance is now available, with the MSRP prices of US$25 for 32 GB, US$45 for 64 GB, US$90 for 128 GB.
