Hard Drive Pass-Through
Also known as transparent data transmission, the hard drive pass-through (JBOD) data transmission method is one in which transmission devices transmit data without processing the data.
With this function, the RAID controller card allows user commands to be directly transmitted to connected hard drives, facilitating upper-layer services or management software in accessing and controlling the hard drives.
For example, when installing an OS on a server, configure a hard drive mounted to the RAID controller card as the installation drive, as opposed to just a configured virtual drive.
