I would love to have purchased another Buffalo LinkStation NAS. However, the Aus distributors don't import NAS models, only external HDD versions. So my only alternative wass to privately import a Buffalo NAS. Which means, if I have technical difficulties I have a lot of trouble to get a replacement. Plus all the knocks from having to travel from the UK/USA to Aus... probably ensures I will have to send it back sooner than later.
You have a web address for an online store in Singapore that supplies Buffalos?
The option I took was the Netgear, had nicer features SFTP, SSH, RAID and 2-bays and was locally available. Those features are all fine and well, but their driver support is PATHETIC! You cannot even copy large files over Wifi to the Netgear NAS. Netgear'sr QA obviously only tests their drivers with ethernet = BIG FAIL!
