SATA to 5x SATA hardware RAID5 Controller

SPM393-SI is a five (5) SATA port RAID Controller. It is designed to provide stand alone RAID array, independent from OS host with data protection and performance aggregation in various applications.

Availability: In stock



SPM393-SI - Key Features
  • Five (5) SATA II port hardware RAID bridge, no drivers required
  • OS independent Hardware RAID with email notification
  • Supports RAID levels: 0 / 1 / 3 / 5 / 10 / JBoD / Clone
  • Provides RAID Manager GUI Utility to configure and monitor the status of the disks connected on RAID controller
  • Supports Hot Spare on RAID
  • Currently there is no limitation on HDD, due to 48bit LBA (addressable up to 64TB per port)
  • Supports Multiple RAID (Configured as Multiple Volume RAID)
  • Rebuild speed: 200GB/hour

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

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

Customer Reviews

Very good, Easy installation Review by Richard Streeter - TENNESSEE
Very good, Easy installation. Sparse but complete instructions. I would appreciate a bit more lengthy installation instructions. Had I not been very experienced in building PCs I would not have understood instructions very well (Posted on 6/9/2016)
Awesome card Review by BradP
I bought this card in 2010 to attach 5 hard drives to make a LARGE volume of 7+TB. It performed great for the almost 5 years I had it. Occasionally the motherboard would drop communication with it (maybe once every 1-3 months) but a reboot would fix that. Note if your sata contoller on your board only supports 2TB volumes, you won't be able to go beyond that with the card. (Posted on 11/8/2014)
