I feel like I'm in a good place to review this item because I own both the Seagate 220 and also the Western Digital MyBook World Edition, and they are competitors. Both are inexpensive network attached storage appropriate for a home office or for home use. For both machines the only feature I use is reading and writing to the hard drive through windows sharing (from either a windows computer or a linux computer). For that reason I will not comment too much on some of the features like automatic backups, media sharing, etc. For the most part on machines of this level those features are gimmicks. They don't work very well and they degrade overall performance of the NAS, as you will be able to read from other people's reviews. When I want to play media from my NAS, I just mount the drive through windows sharing and play what I want. When I want to back up my computer, I copy stuff myself. For the reason I have a generally more favourable view of both of these machines than other people.

Anyway, on with the review. First I will mention two issues I had to overcome before this NAS was reasonably functional for me.

1. This is the big issue I had to fix: This Seagate NAS does not work well with just any gigabit switch. I originally had it plugged in to a TP-Link switch. I could write to the NAS at full speed, but when I wanted to read from it, the speed was horrible. Maybe 1/20th the speed at which I could write to the NAS. After spending a good deal of time researching the issue online I found out the NAS doesn't play well with some routers and switches. Notably it does not work with D-Link switches. Well, I will add TP-Link to the list it doesn't work with.

I've owned the Seagate NAS 220 for about a month now and I have been blown away. The 2 TB unit has two one-terabyte drives and gives you the ability to choose whether you want more space (RAID 0) or more reliability (RAID 1). I opted for greater reliability.

There are three things that really impressed me with this product:

The speed: With the RAID 1 setup, when you read a file from the NAS, you're reading it from 2 hard rives simultaneously, and over a gigabit connection this means I can copy files from the hard drive at 40 megabytes per second. Writing is half that, about 20 megabytes per second.

The power consumption + noise: I figured I would hide this somewhere to prevent hearing it, but its so quiet that I keep it on top of my desk so I can see it. It's visually appealing to look at. Also, the Total Cost of Ownership (TCO) is very low. When reading/writing from the drive, it uses about 18 watts, which at $.10/kWh is about $16 annually if it is running 24/7. It has an auto sleep mode which makes the TCO even lower. Compare this to a PC file server which can cost a few hundred dollars in electricity.

The simplicity: I plugged it in and went to the web based console (no software required) and answered a few questions and I was done. It works from Windows 7, Windows Vista, Windows XP and OS X 10.6. I gave it 4 stars in the features area because it might be a little over simplified, but that is only because I am a power user.

All in all, I'm extremely pleased with it. I will even recommend this product to small businesses who need network storage.

I've worked in IT since 1983. I've had lots of units (Western Digital - UGH!) and this Seagate unit has been the best of it's kind, though it's not for the technologically challenged.

If you are looking for a drive you can plug in and use, you'll need to do a bit of work to get this up and running, but once configured - it's hands off for everything else. I would not recommend this to someone who doesn't have a good understanding of setting up disk shares/users/groups or isn't willing to read up on these subjects to configure the device.

It's relatively easy to setup for the technically savvy but not so easy to setup if you're a computer novice. The machine plugs directly on your home network (router/hub) and can be accessed by any device that will connect to a 'shared' drive. It does not have wireless connectivity, but if you connect it into a wireless hub, you can access it via a wireless device (e.g. a wireless laptop running iTunes or Windows Media or just as a shared drive).

This unit has a 'media service' that lets you publish a share as a music source and access it from iTunes on other computers. It can be accessed via a variety of file sharing protocols so if you've got a mixed environment at home (Windows, MAC, Linux), this machine is great. It also has a wiki feature - though I can't find a use for it at home but might work in a small office environment or if you keep track of things (recipes??) and need a storage mechanism.

This unit also can be configured to send e-mail alerts for various events (reboot, shutdown) and has a web interface for configuration.
