Fastest way to copy files between NASs?
I'm on Windows 7 & want to copy about 500GB of various files from 1 NAS (NV+) to another (Ultra). What is the fastest way, since a straightforward copy in Windows seems to want to take many hours, I ...
This is the way I use to copy my NAS also.
Just wanted to make a minor correction. If you are using a good quality switch and full duplex ethernet, then the bandwidth is not effectively halved when you go through the PC. Each cable can sustain 1 gigabit/second in each direction, and the switch should have enough internal bandwidth to keep up.
There is somewhat less bandwidth available than going NAS to NAS, since the I/O requests and responses are going between the PC and two NAS - but not half. Latency is also improved when you transfer directly. In addition, NFS is more efficient than CIFS for linux systems, especially if you are using one of the older ReadyNAS platforms (which can't saturate a gigabit link).
