3 to 15 years warranty

In a world where the density, capacity, and low cost of NAND storage matter most, the key metrics that occupy a bottom line include endurance and retention rates. For users who want high endurace and retention rates, who want to ensure that their memory cards last a long time, Western Digital’s SanDisk recently launched its microSD Max Endurance cards that promise greater endurance, reliability and are covered by a huge guarantee.

The SanDisk Max Endurance microSD card range includes models with 32GB, 64GB, 128GB and 256GB capacities. Western Digital does not indicate what type of 3D NAND memory it uses for these cards or their terabytes to write (TBW), but it is reasonable to think that these products have some additional NAND flash for overprovisioning and, perhaps, extra controller capacity.

Sandisk now has the following guarantees on its microSD cards:

  • Maximum resistance: from 3 to 15 years
  • High Endurance: 2 years
  • Normal MicroSD: limited duration with limitations

To maximize the longevity of SanDisk Max Endurance devices, they are waterproof, shockproof, X-ray proof and can work with extreme temperatures between -25 ° C and 85 ° C (-13 ° F to 185 ° F).

As far as performance is concerned, SanDisk Max Endurance cards use the UHS-I bus and are classified for reads up to 100 MB / s and for writes of 40 MB / s. The lineup cards support the Video Speed ​​Class 30 specifications, thus offering a sequential write speed of at least 30 MB / s. In addition, the products carry the logos Class 10 and Speed ​​Class UHS 3.
