Intel AXXRMFBU6 MFBU6 RAID Super Capacitor Module

The Maintenance Free Backup Unit (MFBU) is built using NAND flash that can retain data for up to ten years. In addition, it provides near instant optimal RAID performance versus traditional lithium-ion (LiON) battery backup units (BBUs) which are limited to just days of retention and can take up to 8 hours to charge. The longer lasting technology also comes with a standard three year warranty.
