Acer will store your documents. I thought I lost everything when my Acer laptop died, well when I logged in on the new Acer modem, everything booted up including my old documents that I thought I lost, no charge. I am so glad I stayed with Acer because to recover documents it would have cost about $1,000 from my laptop. The other pro about this modem is that it's wireless and it has the capacity for long range. The cons about this and why it's not a 5 star review, it overheats when you plug it into the ethernet cord to hard wire it. Unless you want the insides of this to singe and overheat, you're going to have to go 100% wireless. It makes a really strange fan blowing sound when connected to the ethernet and is hot to the touch.
