Every once in a while you come across a small item that seems potentially frivolous but at the same time very handy. The Seagate GoFlex Satellite Mobile Wireless Storage is in fact one of those things.
It is only 500 Gb which is pretty small for a portable hard drive now a days, especially when it is so easy to pick up a 128 GB USB Flash Drive but this little guy has lots of cool features. The one I wanted the most was the ability to have it use the internal wifi hotspot. You simply fill up the drive via a drag and drop just like every other USB hard drives, then when you unplug, the fully charged drive (yes it has a 5 hours battery life also) you can have it start its own wife hotspot. You can only connect to the device but when you do you can see the pictures, files and movies that you installed. You then stream directly from it. My plan is to leave it turned on in my bag int he overhead on the airplane then stream to my ipad which has alot less space. If 500GB is not enough for you, Seagate has just released a 1TB version, that is $189 on Amazon now. It also allows for streaming from 3 devices where the 500 GB only allows from one, but I did not need that and 500 GB was more than enough for me.
I have just started to play with this but so far it has worked flawlessly and for $120 on Amazon, it is one of those, Why Not? kind of devices. Small enough to drop in the laptop bag and all the extra features.
It takes normal USB but also has the option for the Seagate GoFlex Thunderbolt Adapter (STAE121), I cant justify the $149 for that piece but if you want smoking fast connection to your Mac, then go for it!
