Strengths: large 500GB disk, installation was easy. Mapping to drive on Windows XP was easy.
Summary: Was looking for network storage device that is compatible with Windows Vista and has some level of access restriction capability. This drive was one of the few with these features at reasonable cost. (Other drives with similar features came with software that only ran on XP, at least when I purchased.) Installation onto network was simple. Configuration software worked fine, but a better step-by-step configuration guide would be useful. The disk was east to map on XP, but on Vista I could only map it if I specified the IP address instead of the device name. LaCie says it should work the same on Vista, so problem may be firewall or something. Only gave 3 stars since I've only had it for a few days but it works fine so far.
