MegaRAID SATA+SAS Entry Product Line

MegaRAID SATA+SAS entry controller cards allow small to medium business (SMB) owners and gaming enthusiasts to enjoy the latest RAID technology at affordable prices with low power consumption. This product line delivers trusted MegaRAID reliability with minimal maintenance effort. MegaRAID entry controller cards offer users a straight-forward solution that includes essential RAID levels and uncomplicated configuration options.

In addition, they are able to connect to combinations of SATA and SAS hard disk drives and solid state drives, allowing for storage configurations that optimize cost, performance and robust data protection.

Enterprise Ready

Along with an extensive list of enterprise RAID capabilities, the 9341 series now offers advanced drive diagnostic technologies. In the event of a physical drive failure, the drive is placed in a shielded state and the MegaRAID controller starts drive diagnostics to determine if the drive is indeed failed or can be restored. This saves customers time, money and lost compute time associated with transient drive failures and unnecessary drive returns.

Simple Migration to MegaRAID Enterprise Products

A unique feature of the MegaRAID SATA+SAS entry line is the ability to migrate from these simple, yet powerful RAID 5 controllers to the more full-featured MegaRAID product lines. Users can simply plug in a new controller to recognize and import the existing array without requiring any reconfiguration. Plus, a single management client provides a consistent user interface to manage any MegaRAID SATA, SAS or SSD array.

12Gb/s SAS and PCI 3.0 Performance Advantages

12Gb/s SAS is designed for backward compatibility with 6Gb/s and 3Gb/s SAS and SATA hard drives. Regardless of the drive speed, 12Gb/s MegaRAID controllers will deliver significant performance improvements in both read and write applications compared to their predecessors.
