With DuraWrite you can extend the endurance of your solid state drive (SSD).

Intelligent Block Management & Wear Leveling

Automatically distribute data evenly across the entire SSD.

Intelligent Read Disturb Management

Spread the active read/write across the flash components eliminating data corruption caused by constant use.

Intelligent "Recycling"

Intelligent recycling is designed for advanced free space management as it gradually rewrites data across the SSD over time to ensure data never gets corrupted.


Redundant Array of Independent Silicon Elements protects the data on your drive similar to having a RAID setup.

ECC Protection

With ECC protection you benefit from longer data retention and drive life.
