Average Reviews:
(More customer reviews)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. If I plugged the NAS directly into my Linksys router, the problem went away, but that's only a 100-megabit connection. The funny thing is that the traffic still had to go through the TP-Link switch. In other words, the device this is directly plugged into matters, the rest of the network really doesn't. Anyway I tried various solutions (changing the frame size and so forth). They don't work. The only solution was to buy a netgear switch. If your network has a TP-Link or D-Link switch or router that you'd like to plug this into, budget for a netgear gigabit switch. They aren't real expensive, but I was very annoyed at this problem.
2. This is a small issue, and partly windows' fault: If you create a shortcut to this shared drive in windows and then play a movie from the NAS, it will disconnect 20 minutes into the movie. I originally thought this had to do with the NAS going into sleep mode, but I disabled that feature and it didn't change anything. I didn't notice the problem when playing from my linux machine, and the WD NAS doesn't do this. Anyway, the solution is to actually map the drive in "My Computer" instead of just using a shortcut to get to it. You'd think there would be no difference between those two, but the former works and the latter disconnects after 20 minutes.
Having overcome those two problems, the NAS now functions very nicely for me. The main thing I use this NAS for is to play movies that I have ripped from my DVD collection. They play perfectly on any computer in the house and I can even play two movies on two different computers. Actually I'm not sure how many movies I can play at a time. Nor have I tried playing any HD movies yet, so I can't comment on that, but the speed over my gigabit network seems more than adequate for that.
A couple of comparisons with the Western Digital:
1. This machine is significantly faster than the Western Digital. When I upload to this machine from my Linux box I sustain about 18 or 19 megabytes per second. On the Western Digital I get about 11. This may not sound like a big difference here, but when copying a large file or backing up a whole computer, it makes a very noticeable difference. I don't pay a lot of attention to my download copy speed, but it is above 30 MB per second, whereas I get more like 19 from the Western Digital. I am running this in a RAID 0 configuration. However, I also did a speed test using JBOD and the speeds were exactly the same, so the gain is not really from the RAID (the WD I use has only one HD in it, so there's no RAID option).
2. The Seagate is significantly louder than the Western Digital. It's not loud compared to most hardware, but you can hear the drives spinning if you get close and listen, and when they start up or go to sleep you can hear a click that is pretty noticeable. Sometimes it clicks when no one is using it and you would think it would just be sleeping peacefully. At first I thought this was a hardware problem but it turns out that my NAS is fine. It's just louder than expected. Of course, WD sets the bar high for silence. It is almost impossible to tell if the WD machine is on or doing anything if you ignore the lights on the front (or disable them, as I have).
3. The Seagate is much larger physically. It's not big on an absolute scale, and I don't keep it on my desktop, so it's not a problem, but it's much larger than the WD. The WD is just a hair larger than the actual drive inside it. The Seagate looks like a UPS or something. Anyway I think it looks nice, but one should be aware that it's not as minimalist as some others.
4. The Seagate doesn't try to accommodate tweaks from expert users as much, and it has a much smaller and less active user base. Both machines run Linux under the hood, so if there's a problem with them an experienced user could get in and change things up. On the Western Digital you can enable ssh access through the web interface. And there are bunches of tutorials online about how to fix the technical glitches this comes with and even install new hardware on it. Personally I went in and disabled their media playing software and the software that runs an apple network. Apparently on the WD these things run even though you disabled them and they mess the machine up. Anyway, there is no ssh option on the seagate, so in principle you can't go in and change things. There aren't really help pages for experts. However, recently a user did figure out a way to enable ssh. He wrote an update to the firmware. I used it and it works great, but I can see how some users may not feel comfortable upgrading their firmware in order to get ssh access. Anyway after ssh'ing in, I found that there is one windows bug that the NAS wasn't dealing with well. That is, windows clients delete the last character of the share when they are reading and it causes a bunch of errors to the log, though it still seems to work ok. The workaround is to create another share on the NAS that is not visible, called "Publi", which refers to the same directory. So I'm glad to be ssh'ing in now. Still, for tweaking, it's a better bet to go with the WD. It's been vetted by more linux people.
Anyway, this drive works very well for me. It's my larger and higher performance network attached storage and it is quite reliable for me. When I purchased it, this was cheaper than the equivalent capacity in WD (I use the 4 TB version). In part I believe I'm happy with it because I don't try and use the features that get touted in ads. I just use it as network attached storage. That's true of both drives, and it's what I recommend. The forums for both these machines are full of people ranting about how their device doesn't do what they want and that no one at the company seems to care about them---that's why I say just use it as a remote hard drive. Based on my perusal of the forums, Seagate seems to support their NAS customers less (at least on the forums), though neither company is real great in that respect.
I love both of my network storage devices and I use them both all the time. This seagate is a great buy. When I bought it, at least, it was the cheapest NAS available with this capacity and it turns out to be a very good performer. It's really nice to be able to back things up or store all my large files in one place and be able to access them from any computer in my house. If I were to buy a third NAS, it would probably be another Seagate, just because it's cheaper and faster than the competition.
But make sure you plug it into a NETGEAR device, not a TP-Link or D-Link. I'm not sure about other brands.
