● This is a board that electrically converts SAS standard hard drives to the more common SATA. ● It seems that not all SAS devices will work, but it worked with HDDs in a Windows environment. ● It is also sold on Amazon.com, but it is reported that hard drives with special formats are not recognized even when connected. ● I bought it new, but I no longer need it because I got rid of the SAS standard hard drive. ● Sold as is.
