Results: I/O Benchmark Profiles
We used Iometer’s usage profiles for databases, Web servers, and workstations, simulating file access patterns for each of those tasks.
The 840 Pro performs similarly in the database and workstation benchmarks, regardless of whether you're using a 3 or 6 Gb/s port. But the Web server benchmark heavily favors the higher-bandwidth interface, almost doubling the result gleaned from a 3 Gb/s connection.
