Advanced Technologies Powering the Aura Pro X2
OWC has packed its latest SSD with cutting-edge technologies to improve both performance and durability:
SLC Caching
The Aura Pro X2 leverages SLC (Single-Level Cell) caching, which improves burst write performance by storing frequently written data in a high-speed buffer. This is especially useful when copying large files or working in intensive applications.
Advanced Wear Leveling
This feature ensures that memory cells on the SSD are used evenly, extending the drive’s operational lifespan by preventing any one area from wearing out prematurely.
Intelligent Garbage Collection
Efficient management of deleted data ensures optimal write speeds and drive longevity. The built-in garbage collection system reorganizes free space and clears unused blocks, maintaining peak performance.
