WD my Cloud it enables smb/cifs protocol so a network share can be mapped as drive In Firebird 2.5.x is possible with RemoteFileOpenAbility 1 in the firebird.conf (With a few big warnings if you read the conf file)
you need to take care only the Firebird server to have access to that NAS share (exclusive access) I recommend an usb3.0/thunderbolt ssd drive for io speed If you follow this benchmark "As you can see, performance with random IO operations shows ~8x better results for SSD drive. We knew from our experience with customers databases that SSD is 30-50% faster with real-word applications, but 8x increase is very high." http://ib-aid.com/en/articles/firebird-performance-degradation-tests-myths-and-truth/ http://ib-aid.com/en/articles/firebird-performance-degradation-tests-myths-and-truth/
