I haven't been able to find any benchmarks for the following setup: Intel Cherry 520 SSD x 4 RAID10 with LSI 9260 writeback-cache enabled.

I'm looking to get 1.5gbps sequential

Is that 1.5 Gigabytes/second or 1.5 Gigabits/second? ;) –  ewwhite Oct 19 '13 at 7:59

You won't get 1.5 Gigabytes/second sequential or otherwise on this setup.

The RAID controller and drives you're considering each have a theoretical maximum throughput of 6 Gigabits/second (Gbps), or 600 Megabytes/second. The drive specifications suggest sustained reads of 550 Megabytes/second and writes of 520 Megabytes/second. In a RAID 10 configuration, writes will fall below your expected goal.

You would need more disks to accomplish this.
