Hardware RAID Controller Icon

Hardware RAID Controller Onboard

A high performance RAID controller manages the SSDs you install, supporting Fast (RAID 0), Safe (RAID 1), Volume (Span) and, particularly important to pro audio users, JBOD (Just a Bunch of Disks) configurations, so you can choose the mode that best suits your needs:
Fast Icon

Choose RAID 0 for the best performance.

Safe Icon

Choose RAID 1 for a mirrored backup of your data.

Volume Icon

Choose Span to create a single large volume bridging both drives.


Choose JBOD (Just a Bunch of Disks) to work with twice as many audio tracks.

Regardless the mode you select, changing the configuration is easy – with no software to install or jumper blocks to move around, a turn of a switch and the press of a button is all it takes.
