Hi Shaun, I have seen something very similar on an Oracle X4-2 I added two 256MB Samsung 850 PRO and created a mirrored zpool The system zpool was a mirror of two SAS Seagate 600GB which came withe the system. The system was running Solaris 10 with latest patches. After a few hours I saw checksum errors on both disks. Oracle told me they did not support the Samsung disks so I swapped them for Intel DC S3500 which have been working fine for months. The 850 PRO drives worked fine on a X4140 but this has a different raid controller. So I guess you need to be careful which SSD's you use with certain controllers :-(
