HP xw6400 Mini White Paper

Benchmarks
The charts below compare the performance of the File Server workload and Workstation workload
using the IOMeter test harness. The charts show the performance improvement of a 4 disk RAID 0
configuration over a single disk configuration.

Results
As shown in the first chart, the 4 disk RAID 0 array has a clear performance advantage for the
Workstation workload – almost 3x as fast for SATA disks, almost 5x the performance of the 10K SAS
disk, and almost 8x as fast as the SAS 15K disk. A similar result is seen for the File Server Workload.
For those who need the best performance, regardless of cost, a RAID 0 configuration of SAS 15K
disks can be a great choice. The 10K SATA Drives are also relatively fast and represent an excellent
price/performance tradeoff, as the SAS drives are relatively expensive.
