SPM393 uses market-proven Multi-port Serial ATA PHY technology and a proprietary storage processor to provide very highly efficient SATA RAID operations.

With an easy configuration scheme, the device can function as a pure port multiplier which provides SATA port expansion just like a SATA Hub, a hard drive performance booster which provides a high-performance device seen by the host controller, or a hard drive data protector which automatically backs up data to prevent data loss from hard drive damage.

SPM393 also has an advanced mode to provide both the benefits of performance boost and data protection.

SPM393 has a self-contained storage processor chip which completely frees up the main CPU loading and whose SATA ports comply with the eSATA specification, making it suitable for use in both internal system and external storage applications.

Here are how easy to change configuration of SPM393. Set rotary switch to:
• PM (Port Multiplier technology) allows system to see 5x individual drives - Default mode
• RAID0 - All installed hard drive set as stripe raid
• RAID1/10 - If TWO (2) drive installed, these will set as mirror raid, where 4 drives installed it will set as RAID10 and the fifth drive sets as Hot Spare
• Large - Combining / appending all installed drives as a ONE BIG volume, hdd size is indiscriminate
• RAID3 - All connected HDD will set as RAID3 - for more info about raid3 go here
• Clone - All connected HDD will set as mirror with N copies. Like raid1, which is 1 to 1 (mirror), Clone is 1 to n, where n is the number of installed HDD
• RAID5 - All connected HDD will set as RAID5 - for more info about raid3 go here
