The Vertex 3 (sandforce controller) --each spec'd at 500+ Mbps read/writes. I have 8 attached to an Areca 1880i (6Gbps) in RAID 0. Every few days, I get an alarm followed by a reboot. I am running Server 2008R2. I had a stable machine for nearly two years running a 4 port Areca and 4 first generation OCZ Apex SSD's (about 175 Mbps read writes each) . The intent of the upgrade was to increase capacity and speed. Thanks for all replies in advance
