4 out of 5 eggsPretty good box

Pros: Reasonable price, small footprint, easy to install the drives and set up the OS. Lots of features.

Cons: Volume set up and file transfer is pretty slow, but I guess that is expected for this type of system. BEWARE OF INCLUDED SATA CABLES! I have had several problems with drives dropping out of RAID or HDD and Volume showing problems that could not be solved with a new drive. A little research in their forums indicates that this is a fairly common problem with a common solution of replacing the SATA cables. Guess what, they must use the cheapest cables they could find because since I have replaced them (purchased new short cables) I have had ZERO problems WITH THE SAME DRIVES. Since I use this at home for non-critical file storage (DVD backup), I didn't lose anything important that couldn't easily be recovered. Hence the rating only lost one egg. However, I would be VERY upset if I was using this for critical files or file backup.

Other Thoughts: I have had the unit for almost a year, and aside from the few problems I resolved, it has worked pretty well. Just make sure that you get your own SATA cables and don't use the included ones if you want to avoid the problems. Google is your friend to find quality short cables that will work for this. Definitely do not recommend for anything critical, I would get a dedicated server or proper backup solution for that.

4 out of 5 eggsSlow, but worth it

Pros: Well, what can I say. For under $300.00, you get a 4 bay NAS server. I'm using 4x2GB drives right now, and it does what it says it will do. The interface is top notch, and there are tons of extras (be sure to upgrade bios). I've got FTP, iSCSI, CFS and NFS all running just fine. Call it $190 per 2TB drive, and you end up with a 5.5TB storage array for about $1000.00. Read speeds much better than write speeds, I have no problem with playback (as an added bonus, the first one I have is acting as a Video Server that works with my Dlink Media Server.

Cons: It's slow. I mean, DEAD slow. I've had it for a week, and am STILL moving my data to fill it up. Averaging about 6MB/sec, which means I am moving about 500GB/day to this device. I've ordered 3 more, but these will be using 1.5TB drives (call it 4TB of storage), since the 1.5 drives are only a bit over $100.00 each, actually a better price/GB. And rebuild? Don't even get me started. I started with 3x2TB drives (one was dead), and then expanded when I got a 4th drive (shipped broken one back to newegg, very fast turnaround), and it took me a good 50 hours of waiting to 'expand' the array to it's full 5.5TB size. That's why I'm still copying stuff.

Other Thoughts: If you need cheap, reliable storage, VERY easy interface, plug-and-play high density storage, this is the device for you. As long as you are willing to wait a long time for the data to copy, it works fine. As a day to day working NAS (i.e. production enviroment), avoid it. Too slow to be used on a daily basis, but if you need a redundant, cheap, dense storage solution, I'd consider this one. I need 'space' much more than I need 'speed', so this is a good solution

1 out of 5 eggsGreat UI, very unreliable hardware

Pros: It has a great software package for administering the system, and lots of nice, handy features.

Cons: The hardware is extremely unreliable.

It ran great for about 8 months and then started acting up. It does not ship with any OS software and must instead be installed from the included CD onto one of your disks (there is no internal storage). For a month or so the system would routinely become unresponsive and upon reboot it would "forget" that it was even installed, forcing me to reinstall from the CD. Luckily, this did not affect my DATA at all, but it was very annoying. Eventually the problem grew worse, freezing up after only a few hours online and soon it wouldn't even detect the system anymore so I could no longer reinstall nor get any sort of response from the system.

From looking at the forums, this is a very common problem. Support was not very helpful, asking for kernel dumps/logs which I had no way of getting since I can't bring the system up. I don't think they have a fix for this and since I'm out of warranty, they won't give me a replacement.

Pros: Performance is as advertised on their website

Cons: Performance is as advertised on their website

Other Thoughts: I thought I'd add this update to show where to find info on their products

3 out of 5 eggsSweet setup, but is sub-100mbps

Pros: The OS is stable, the GUI to manage it's features is intuitive & it has a rich feature set.

Cons: 80-90mbps speeds, not 1Gbps like is advertised.

Other Thoughts: For the low price, it's a nice little unit for your average home with 100mbps router on 2 or 3 devices. For me, I have a 24 port gig network for a reason and do large amounts of data transfer. I fully expected 250mbps like a PCI gig nic would perform for this price but not sub-100 speeds! Too bad, cuz it makes the device useless to me...

5 out of 5 eggsLove It! Many Features.

Pros: - It has been 100% Reliable for me. I have never lost any data. I use RAID 5 w/ 4 Samsung 750GB HDs. I removed a drive just to see if it worked and it worked fine.
- I use almost all the features: BT downloading, FTP Server, Web Server, Photo Station, and the backup features. (The only feature I don't use YET is the surveillance server - but I will next month!)
- It streams my 1080p content flawlessly to my Vista machine.
- Synology has frequent firmware updates, extensive forum support, and a reliable technical support team.
- The built-in backup utilities work fine (although I use SyncBack SE).
- It uses standard Linux RAID. In case of a hardware failure, you could recover the data with any PC in Windows using UFS Explorer Pro (or any similar proram) or install the drives into another Synology drive.
- Synology has released a free "package" which adds an email server feature to the drive.

Cons: - When using all the features simultaneously, the machine gets bogged down a little.
- Even though it has gigabit LAN, the transfers are a little slow (about 5-7 MB/s write, 8-11 MB/s read). I use ALL of its features, though. Would probably be faster if I disabled some.

Other Thoughts: - I own 2 other Synology drives (DS107e) and love them. I use one for business purposes and have it automatically backup its content to my other DS107e kept at my brother's as an offsite backup. Works great.
- As mentioned by other users; the system can get boggy if you use many of the advanced features. If you can afford it, I would recommend upgrading to the CS407 (has faster processor and twice the memory) or the newer 408 and 409 series.
- I purchased a 1.5TB external HD and have the CS407e backup to it every night using its internal backup software.
- It seems to handle two large-file transfers simultaneously without lag, but when three or more users are pulling from it (or if it's performing a backup) it will lag some, but it has never failed to finish any transfers for me.

5 out of 5 eggsExceptional Interface

Pros: This NAS unit has an exceptional web-based interface, and with the latest firmware update, it has a wide variety of options to choose from. We bought it for our small business to handle shared user home directories and server backups. We also puchased it for its support of the NFS protocol to allow Unix/Linux to mount the file systems (requires firmware update out-of-the-box).

Cons: It would be great if this model of NAS supported a slide-in/out (hot swap) mechanism for disk drive replacement. Having to screw in and cable each disk is time consuming, requires down time and is overly optimistic. A drive failure will happen; it's just a matter of when. So, hope for the best but plan for the worst, and provide a hot swap mechanism.

Other Thoughts: Yes, others may have problems with certain brands and models of disks in a RAID configuration in this or any other NAS. This is true of any hardware RAID solution; you have to check compatibility. No, I don't work for Synology, I just know the ins and outs of hardware RAID. After a firmware upgrade, this unit supports RAID6, but with 4 disks it gives you the same capacity and redundancy as RAID1, so why not just do RAID1? (I guess it just gives them one more thing to tout under their "supported" list.)

1 out of 5 eggsBeware

Pros: Cheap, with promising feature set.

Cons: Poor performance, unreliable, unresponsive and perfunctory support. Software RAID is unreliable and poorly implemented. DO NOT trust the built-in RAID 5 configuration. Producer web site is misleading and you should double check which hard drives they are supporting.

Other Thoughts: Our company has had two of these devices and both have had numerous issues resulting in data lose. Synology support will not help you. They will send you an email stating that it is your problem and they cannot help. I am not sure how they have received even a passable rating here on Newegg. If you doubt the veracity of my claims, just check the forums, including Synology own forums. You will see a near epidemic of failures.

4 out of 5 eggsBasic Home Server

Pros: Best server I used so far, A lot of features build in. Don't have to install any software on your computer to use server. This has photo stations so you can share photo with friends and family over the internet. Got email tech support in 48 hrs. Always updateing bios.
Fans are very quiet, and only 1 fan.

Cons: Need to turn off bt download to stream huge video files or turn off upload on it. Slow if you are doing multi things at the same time. (I'm a heavy user)
Need to update the bios once you get it.

Other Thoughts: If I have a little more money I would purchase the CS407 or the CS408, but I spend it on the hard drives.
I have tried many other Nas Server, Best one so far i have used. But watching streaming movies you will need to turn off the bt download. I use 4x 1tb WD greed drives on this, so I would expect it would be slower with these huges drives. Bottom line, if you can't afford cs408 or cs407...this is the best server to get and you will be very happy with it, beside the speed thing...still a lot faster then a lot of other server i have tired. I have spent the last 3 weeks doing research from testing other server and reading website on many servers and found this to be the best one out of all the ones for home use, under the $0-$400 budget. For the cost of this server and what it can do, its extreme deal. Best price is here on

5 out of 5 eggsHighly Reccomended - Great Consumer Support

Pros: Lots of features and firmware is constantly updated to included improved and new features. Great support from Synology for a consumer level product. Even better than the Enterprise Level HP support my company pays top dollars for. Sang and his team from Synology was very helpful just now when I had problems expanding my volume. I setup a temp password for them to log in. They troubleshoot and manual expanded the volume for me over the course of several days remotely.

Cons: The Expand Volume option did not work without tech support. I dug through many forums and many people did not have the issue and it appeared only a handful of users did so I do not believe it to be a common issue. Still highly recommended. This box has lots of great features not found in most other boxes.

Other Thoughts: I would highly recommend any NAS enclosure from Synology.
