Backup and restore functions are easily the most strenuous for a NAS server. These operations require a lot of CPU power and when paired with RAID 5 and 6 can bring a good NAS down to really slow transfer speeds. Great products take the stress and push through it.
Here we see the QNAP TS-509 Pro excelling at the restore function and doing a decent job with the backup. To date the TS-509 has given us the best backup performance, but with a larger memory module installed I think the performance could be even better.
