Just a "me too" here, running a mix of 16 consumer-/servergrade SATA-drives (WD and Samsung) on a LSI SAS2116 (mps, flashed with IT firmware (JBOD)). Drives are connected with a SAS-4x SATA cable (1m length). I've been running regular scrubs and encountered no problems at all so far - the system is used as a file server with low usage though. FreeBSD version is 10.1-BETA1. Bye Marc=20
