QNAP Pro II 4-Bay Desktop Network Attached Server TS-439 Review

Average Reviews:

(More customer reviews)
I have owned my TS-439 ProII for a couple months now and have been very happy with it. The build quality is high, the unit is quiet, it has been reliable, and has met or exceeded most of my expectations. I have witnessed a few quirks with the software which is to be expected on a device this feature rich and new (No show stoppers). The good thing is that QNAP does very regular firmware updates, constantly improving the features and fixing known bugs. QNAPs forums are also a great resource to learn about the NAS and get assistance from fellow users when needed. Over the course of my ownership there was one human error induced issue I had and QNAP's support was quick to respond and get my NAS squared away. It will take more time and use for a full review, but after two months I am still very happy with my purchase and would purchase another without a second thought if the need arose.

Synology America Corp DiskStation 4-Bay USB 2.0 Network Attached Storage DS411slim Black Review

Synology America Corp DiskStation 4-Bay USB 2.0 Network Attached Storage DS411slim Black
Average Reviews:

(More customer reviews)
As far as I'm aware this is the first 4 bay 2.5" NAS on the market. It came out over a year ago but hasn't received very much attention, which blows my mind, because it truly is a wonderful device. It combines an incredibly small form factor, a gigabit ethernet port, and a wealth of advanced options like a webserver, bittorrent client, FTP server, IP camera system, intelligent RAID configurations and Synology's renowned Disk Manager software. When you consider how many features are packed into this tiny box, its low price, and its lower noise and power consumption compared to much larger and more expensive NAS enclosures, the 411slim is a no brainer.
Currently I have 4 Western Digital 1TB Scorpio Blue drives in this enclosure in a RAID5 array. At the time of this review, 1TB is the largest 2.5" drive available, so yes, you're limited to half the storage capacity of a normal 4 bay 3.5" NAS. However, don't let this scare you away. 1.5TB and 2TB 2.5" drives are right around the corner, and as long as those drives don't exceed 12.5mm thickness, you should be able to scale upwards to 8TB and subsequently get some real bang for your buck with this machine.
Speed is on the slow side - don't expect it to rival a ReadyNAS with aggregated ethernet. But considering the way I use this NAS - as a repository for all my video, music and photos, with direct playback via USB to my Popcorn Hour network media player - speed is secondary. I love having something that is out of sight and out of mind (and out of hearing range). I can always do massive file transfers overnight while I'm sleeping. If speed is paramount to you, look into traditional 3.5" NAS solutions. But if you plan to use this as a backup drive or as media storage, without constant R/W or high-def playback to other networked machines, then this is the perfect NAS.
I can't say enough about the 411slim - it is a remarkable piece of computer engineering, and while it won't rival the performance of a traditional NAS, its other features more than make up for it and set it apart from the rest of the NAS pack.

Drobo FS 5-bay Gbe Storage Array Review

Drobo FS 5-bay Gbe Storage Array
Average Reviews:

(More customer reviews)
I owned the original Drobo when it first came out, but ended up selling it due mainly to how noisy it was. The ease of use of the Drobo kept me interested in the products however. I'm happy to say, this is drobo is much improved. It's not silent by any means, and is probably louder than it has to be, but it replaced the blower with a regular fan and is much more tolerable. It takes a LONG time to boot after a shutdown (around 10 minutes)
Transfer speeds are not really anything to write home about. I'm getting between 24-27 MB/sec uploading large media files. That will be fine for my uses, but if you're doing a lot of data manipulation on this as your primary storage, you may be disappointed.

Cavalry Storage CADA-SA2 Series 1.5 TB USB / eSATA 2-bay RAID Personal Disk Array CADA01ASA2 - Includes eSATA Kit Review

Cavalry Storage CADA-SA2 Series 1.5 TB USB / eSATA 2-bay RAID Personal Disk Array CADA01ASA2 - Includes eSATA Kit
Average Reviews:

(More customer reviews)
I bought this drive array based on overall reviews for Calvary arrays, and the fact that it was pretty inexpensive. After getting it I was able to determine what chipset and drive manufacturers were used and I'm very happy with the components.
The chipset is Silicon Image Sil5744 and the drives are new Western Digital Caviar Green drives with a 16MB buffer.
I did see a review for the 1 TB model where the reviewer complained about the fact that the drive came configured in a stripe instead of a mirror. Their website and product specs all state that it's configured for RAID 1 (mirror)... but mine was also configured for RAID 0 (stripe) when I got it.
Their manual recommends using GUI mode for RAID configuration and I sent an email to support asking why. The response was that with GUI support you can use the Steelvine software to monitor the drive. However, Silicon Image documentation states that Steelvine will work in a Status-Only mode when RAID is configured using the rotary dial. I definitely wanted RAID 1, configured it using the rotary dial, installed the Steelvine software, and found that I still have the ability to monitor the array and even configure notifications and verification tests.
Other than the fact that the drive came configured for RAID 0 instead of RAID 1 the only other nit-pick I had was that the opening for the rotary dial is small and it's difficult to see the actual numbers. The ones on the case don't match up to the actual numbers on the dial. I found that the only number I could see was the one selected because of the groove in the dial. As a result, I had to try and see what it was on and then count the clicks to set the configuration I wanted. It was set for GUI (7) and they do seem to discourage you from changing that.
Overall I consider these minor issues and decided to give the array 5-stars based on the quality of components used.

Acer Aspire easyStore AH340-U2T1H Home Server Review

Acer Aspire easyStore AH340-U2T1H Home Server
Average Reviews:

(More customer reviews)
QUICK SUMMARY: Acer's AH340 server, when configured correctly, provides home users and small offices a powerful solution for automated backups, restores, remote access and media server capability. However, configuring this server can be challenging, and Acer makes little effort to help its customers. Microsoft's Windows Home Server is a terrific -- and stable! -- operating system. Add a 2nd hard drive, too, and you've got redundant data storage. Cautiously recommended.
*** SPECIAL NOTE as of December 31, 2010: If you're in the market for a Windows Home Server, you should know about a few announcements that occurred in November, 2010. One, Hewlett-Packard is getting out of the Windows Home Server market. They won't be making HP Mediasmart home servers any more. HP sold the most number of Windows Home Servers, and people are speculating whether this move will effectively kill the Windows Home Server market. Two, Microsoft announced that they are removing Drive Extender from the next version of Windows Home Server (Version 2, code named Vail, which will be released in 2011; Drive Extender technology is included with WHS Version 1, which runs these Acer servers). Drive Extender is a critical piece of technology that allows you to easily add more hard drives to your server, have a single pool of storage for all your data, and it provides for data redundancy (so if one hard drive crashes, your data is kept on a 2nd hard drive, provided you've added at least one more hard drive to your server). Microsoft will provide full support to this version of WHS until January, 2013, and then it will not be supported any longer - no bug fixes or security enhancements.
*** SPECIAL NOTE as of February 6, 2010: McAfee Antivirus automatically updated their software to Version 5, which totally screwed up my server! STAY AWAY from McAfee!! If you buy this server, immediately use Remote Desktop to open the server's Control Panel, choose Add or Remove Programs, and uninstall McAfee from your server! McAfee cannot be trusted! Read the end of this review to learn more.
What follows is my review of the Acer Aspire AH340-UA230N Home Server, based upon my personal experience with it since purchasing one in late June 2009. For 2010, Acer has refreshed their Windows Home Server lineup using faster RAM and the Intel Atom D410 and D510 CPUs which have a slight bump in processor speed and, for the D510, more L2 cache. Other than this, the AH341 and AH342 servers are *exactly* the same as the older AH340 server.

*********************************************************
If you read this very long review, you'll learn quite a bit about this Acer server and the Windows Home Server operating system. You'll also read about some minor issues I've run into, and how to workaround those issues. I've owned this server for six months now, and it's been a good experience overall. If you buy this Acer server, you're not going to get much help from Acer. So for any problems, your own technical know-how and the Internet community are your best sources of help.
In short, I bought this Acer server and successfully installed it on my home network. In very large part, it's doing what it's supposed to be doing, that is, it automatically backs up my four-computer home network, and it gives me remote access to my data, too. Thus far, I have only one small, re-occurring issue which I'll share in a moment.
The out-of-box experience is pretty good, but don't expect much by way of documentation. You'll need to look elsewhere to understand all the ins-and-outs of using Windows Home Server (WHS). Although the "Quick Start" booklet seems very thick, it's actually got the instructions in about five or six languages, and so when you read the English section (if you read English), you'll only see how to set-up the server with a little narrative and black-and-white screenshots that are difficult to read. Fortunately, the setup is pretty easy, and they do include a larger poster with just the absolute essentials (which is what I used), and the poster was good enough. In short, plug-in the ethernet cable from the server to your wireless router, and you're in business. The server is heavier than I expected, and *quieter* than I expected (much less noisy than my desktop computer).
Then, you install a CD in one of your available networked computers to install the Server Console on the installed-from computer, and to begin configuring your new server. One things stands out in my mind here...the instructions say turn-on your server and wait until the blue LED light is glowing steady. Trouble is, there are about seven or eight lights glowing at this point (one light for each of the four disk drive bays, a power-on light, a network light, an "information" light, and possibly a disk activity light), and some of the lights glow purple, not blue. Suffice it to say that you should wait a few minutes just to make sure everything is settled before you start server configuring.
The server configuration went pretty well, I thought. Do a Google search for "Acer Windows Home Server Review" and you'll find a website where someone has very helpfully documented the entire install process using color screenshots of each step. The installed server console program (running on one of your networked computers) is not resizeable and won't maximize, which is annoying. You can use Remote Desktop Connection to actually login to your new server (if you're not familiar with Remote Desktop Connection, it lets you connect to another computer from the computer you're using).
In a very short time, my old, quirky Gateway desktop computer (circa 2003, XP Pro, 2Ghz CPU, 512MB RAM, 80GB HD) was recognized by the new Acer server, and I was creating user accounts on the server that match my desktop computer (you should use a password on your user accounts, and be sure to specify the same password on the server as what you use for the desktop/laptop account).
At this point, I had my first problem -- the Gateway's connection to the server would get lost inexplicably during the first attempt at a manual backup. Long story short, I completely reinstalled Windows XP Pro SP-3 on the Gateway desktop, reinstalled the Windows Home Server Console, and was able to begin getting successful backups until I got to the point where I restored all my digital media files (using Acronis and an external hard drive -- not using the new Acer server) and then tried a WHS backup, which fails inexplicably. Could be my aging and quirky Gateway hardware, but it's a fresh install of XP and the error messaging is vague and unhelpful.
Notably, my three laptops (running XP Media Edition w/1GB RAM, Vista Ultimate w/2GB, and Windows 7 Ultimate w/4GB of RAM) backed up their contents perfectly -- no troubles at all, even backing up a very large VMWare virtual hard drive (which is a single, physical, 20GB file on my Vista laptop).
Very cool feature: This Acer will wake-up either a sleeping or hibernating computer to do the backup in the middle of the night! So, don't turn-off your computers, just put them in sleep/hibernate mode so they don't use much power, but will still get backed-up. (Note: WHS does *not* use Wake On LAN technology, which doesn't work reliably in all environments - the WHS technical strategy for waking sleeping/hibernating computers works much better than WOL). The WHS backups are incremental, so you can return to any previous point in time during a restore -- you aren't limited just to what was done last night. This is handy if you want to restore your computer to the way it worked one month ago, when it was working reliably (you'd probably do a 2nd restore, then, to load all your most recent data following the system restore).
To get remote access to work correctly, you need to modify your ISP's modem setups (your ISP's modem most likely has a built-in router, too). Choose "Bridged over Ethernet" protocol in the modem setups, and then configure your wireless router that's attached to the modem so it is a PPPoE connection (you'll need your ISP's account name and password for the router configuration). Once I got through this headache, I was able to gain remote access to my server -- very cool feature!! (BTW, don't count on any technical help by AT&T/Bellsouth - you won't get any that's helpful to you). You may also have trouble if your ISP blocks certain ports, like ports 80 and 443.

24/7 Global Access with Microsoft Windows Home Server The Microsoft Windows Home Server operating system centralizes digital media in one location, making it easy to access files, photos, videos and music from any PC on your network. It also protects critical data by creating an image-based backup of every home computer every day, so you can restore a single file or an entire PC. With Windows Home Server, users can access the home network from the office or the road, for full access to their files and applications, just as if they were sitting in front of their home PC.
For example, parents can access their children's homework while traveling for business. They can also upload videos and photos from sports events or summer vacations to the server, even while away from home. At any time, from anywhere, every family member with a PC in the home network can access photos, videos, music and other documents from the home server.
This centralization of digital data saves significant time by eliminating the need to transfer data from one PC to another, every time someone wants a photo, video or other document that's stored on another PC. It's also a safeguard. If a netbook or notebook is damaged, lost or stolen, users don't lose their data along with it, since it's backed up at home. In addition, when a new system is added to the network, it's quick and easy to upload data from the computer to the server.
