About RedPort SAS


Lawyers, forensics investigators, and techs who want to add write-blocked ports to a Windows or Linux computer rely upon the CRU® WiebeTech® RedPort™ SAS. Connecting a storage device to our RedPort on the back of a computer means the attached device is write-blocked.

RedPort works much like our forensic docks, preventing writes to drives and storage devices. But instead of being an external docking device, RedPort is a PCIe card and driver, and works within the host computer to allow write-blocked access to enclosures or drives with one of several connection types.

CRU’s RedPort host cards and drivers are developed in partnership with ATTO Technology, a global leader in storage interface connectivity. We’ve leveraged their years of experience with SCSI, Fibre Channel, and SAS technology with our knowledge of our customers’ work environment and requirements.


RedPort SAS uses standard multilane cables to connect to SAS (Serial Attached SCSI) or SATA (Serial-ATA) devices at up to 6 Gbps speeds. This is our newest addition to the RedPort lineup, and our first write-blocking solution for SAS drives/enclosures.


Additional features:


  • 2-year warranty
  • Free US-based customer support


Whether you’re a forensic investigator, technician, or cyber security analyst, the RedPort SAS card is an important part of your toolkit. Find a reseller near you or buy online.
