Advanced technologies
RAID ECC
RAID ECC is an advanced Exascend technology that combines the power of RAID with NAND flash block granularity, allowing the storage device to rebuild even severely corrupted data.
Custom Data Sanitization
The best way to purge data rapidly is the way that works in tandem with your applications and operating procedures. That is why Exascend offers fully customizable secure data sanitization that leaves no data behind.
Data Retention Plus™
Data Retention Plus™ dynamically refreshes data stored on the Exascend storage device based on usage patterns. This facilitates even drive wear leveling and strengthens data retention.
Write Protection
Triggered by the user using either firmware or hardware, write protection technology safeguards data stored on the flash storage device by setting it to read-only mode, thereby blocking the host device from deleting or making any changes to the data.
