Winchester Disk Performance Benchmark Tests Results


The winchester system we tested is a 690GB FlashDisk RAID Storage Array (Winchester: WINSYS, Model:Flashdisk G6). We utilized a Raid5 configuration with 673GB usable disk and 1 failover disk . It is attached to a 4U server. The following are our test results using bonnie++ and tiobench:
