Pros Multi-functional use Door Stop/Paper Weight
Cons Doesn't Mirror, looses drives, looses connection.
Summary Tested on both computers:
2012 Macbook Pro
2012 Macbook Air
10 years of networking, MSCE Cert / Network + cert.
Opened ports on the cisco router, tried a 3tb usb3.0 drive and a 2tb usb 2.0 drive, same results.
Finder runs unbearably slow when I start browsing drives, it's so sluggish that it can't even stream a 600meg movie without it stuttering. I can share drives over the network between macs and copy files just fine but when I use the pogoplug 4 it's unbearable.
Simple file copy operations of large groups of files fail on the pogoplug when they work just fine between computers and on all external drives when connected to my macs.
Not only do the file copy operations cripple the drive but there is no throttling so attempting to even browse the drive will freeze finder.
