For high-load, multi-streaming environments like media serving, the 3ware® SAS 9750-4i4e 6Gb/s SATA+SAS RAID controller card has both internal and external connectivity to support scalable storage with RAID data protection for compact servers and workstations. The external ports can be used to offer significant external storage capacity as application data needs expand. StreamFusion®+ technology balances data streams to help mitigate bottlenecks and ensure multi-streaming performance.

  • Connect up to 127 SATA or SAS drives with 4 internal and 4 external 6Gb/s SAS ports
  • Fit into compact servers and workstations with low-profile form factor
  • Bandwidth to support critical applications with PCIe® 2.0 connectivity
  • Read-ahead caching accelerates performance even in degraded volume states
  • Pick the right balance of protection and performance for critical applications with RAID levels 0, 1, 5, 6, 10, 50, and single disk
