Rescan - taking a long time

[simoncn]

Your current model has 256 MB, which is marginal for a library of your size. You can check memory consumption by looking at Resource Monitor in DSM. I would expect you are probably OK for memory at the moment but it would be advisable to make sure you have 512 MB when you upgrade.

Performance is a combination of disk speed and CPU speed. Your disks are fine and there is no need to change these. I think the speed improvement with a dual-core 1.3 GHz CPU would be noticeable. Your rescan time might drop by about 2 to 3 minutes but I can't guarantee this.

The processor type can make a difference as well. Which NAS model are you considering?
