File Copy Test - Creation
File Copy Test is a pseudo-real-world benchmark that times how long it takes to create, read, and copy files in various test patterns. File copying is tested twice: once with the source and target on the same partition, and once with the target on a separate partition. Scores are presented in MB/s.
Striping flexes its muscles in FC-Test's file creation tests, and performance scales nicely from two to four drives. The performances of the two-drive RAID 0 and RAID 10/0+1 arrays are nearly identical, as are the performances of our single-drive and RAID 1 configurations. RAID 5 performance is dismal, though. Parity must be calculated every time data is written to the array, and in a file creation test, that's all the time.
Although both RAID 5 implementations are slow in this test, the nForce4's performance with parity is consistently ahead of that of the ICH7R. However, the ICH7R proves faster with three- and four-drive RAID 0 arrays.
