  • New hardware and software storage system that involve managed solutions with integrated technology

  • Cost-effective MLC-based design with best-in-class endurance.

  • Advanced feature-set includes user-selectable data recovery & non-stop modes.

  • Proprietary Virtualized Controller Architecture (VCA) 2.0.

  • Data fail recovery ensures superior reliability.

  • Intelligent block management & wear-levelling for increased endurance.

  •  Advanced security with 256-bit AES encryption support.

  • Strong error correction for enhanced data integrity

  •  It includes power loss data protection.

The xM84s are half height solutions with four controllers while the xM88s are full height with eight controllers.  The main difference there is the support for power failure protection. The R-series boards have an array of capacitors that can store enough charge to flush all pending NAND arrays in the event of a power failure. The C-series boards do not have this feature. This is a best feature in the R-series
