"This is a slow, simple network drive already being abandoned by software updates."
Buffalo's 'Subscription-Free Personal Cloud' means this box connects to your router, letting you access files remotely. However, performance will be a fraction of what you get from paid services like Dropbox or Google Drive, and setup is entirely manual.
This is for a Windows user who needs a simple, low-cost network location to back up a single computer. The buyer must understand this is not a high-performance device and does not protect data against drive failure.
Anyone with a modern Mac should avoid this due to stated software incompatibility. Anyone who values their data should seek a two-bay NAS with RAID 1 for drive redundancy. Users wanting to stream media or run apps should look at other brands.
