Benchmark Results: Windows Backup
Since the RAIDFrame is a backup device, I decided to see what the backup performance would be like on each RAIDPac configuration. I also added a couple of the other drives for the sake of comparison, including our internal SATA Seagate Barracuda 7200.11 1.5TB drive and a USB SimpleTech (re)drive external drive. For the backup software, I stuck to using the Windows Backup Utility that comes with Windows Server 2003. I generated a directory of 782 files totaling 30.1GB and ran five backups to each drive using a quick batch script that executed the Backup Utility via command line.
For granularity’s sake, I decided to show the resulting times for each disk’s five tests. The fastest average backup time goes to drive I:, which is the RAIDPac configured with three 1TB disk drives set to RAID 5. The fastest this RAIDPac finished a backup job in was 2,548 seconds (roughly 42.47 minutes), and as the illustration shows, three of the five test runs ran in under than 2,750 second mark.
The drive with the slowest average backup speed was the SimpleTech external USB (re)drive, which should be expected, since it’s the only non-SATA connected drive in the test. Compared to the SATA disks, none of its test runs finished below 2,750 seconds (45.83 minutes).
The last test I ran was a full recovery of all 30.1GB worth of files from each of the disks, including the SimpleTech (re)drive USB external drive. As in the backup test, I ran the Windows Backup Utility to see how long it would take to get files recovered from each drive into a designated local folder on the main disk. The average presented is based on the drives being tested five times, one after the other. This produced the following results:
