FreeNAS Review

I promised in my last tech post that this entry would continue, and hopefully conclude, my journey towards the perfect Network Attached Storage (NAS) system.  The primary reason I want to use one is to stream TV Shows and Movies to my Samsung 40” LCD TV in my Living Room by means of my AppleTV.  It also serves as a backup location for my important files, and is now capable of performing server related tasks that were previously handled by the AppleTV.  This is my 4th attempt at a NAS solution for the Spitfire Network, the most expensive, the most capable, and finally…the most likely to survive.  For a quick NAS summary:

NAS Solution	Judgment	Cost
Eclipse (Gaming PC)	Too loud, power intensive, resource hog no redundancy
Apple Extreme Wireless Station + USB HDD	Ran drive continuously leading to failure no redundancy
Linksys NAS 200	Ridiculously Poor Performance, Noisy
Atom / FreeNAS	Best of all worlds but expensive, large footprint

I tried all the cheap alternatives to buckling down and forking over the cash for a decent NAS / Server but in the end the only lesson is one we should all be familiar with already - You get what you pay for.  In trying to be cheap, all I got in return was lost data (Apple Base Station) and unusable performance (Linksys + hosting files on my gaming pc).  Not that a FreeNAS solution has to be expensive however.  These days many people have a spare PC in their garage or something.  All it needs to be given new life as a FreeNAS server is:

x86 Processor
128 MB ram
32 MB disk space
Network card

The catch is that your hardware has to be supported by FreeBSD, but I’d be willing to bet that if it’s anything similar to a commercial computer, you are all set.  I looked into the option of buying a cheap, used PC for under $100 on craigslist but in the end I decided to build a new PC specifically for a few reasons:

1. I knew exactly what hardware it would have, with warranties.
2. By using an Atom chipset it has power consumption comparable to a netbook, which is preferable to a power hungry P4
3. The Atom D510MO chipset is fanless, making the entire computer almost silent
4. Gigabit Ethernet (up from 10/100 on the linksys nas)

I bought a nice looking glossy black case from Newegg, which was running a pretty nice deal on it as long as I signed up for spam, and sold the Linksys NAS for $5 profit.  I had the disk drives already from the linksys raid setup, so in the end I just had to buy the case, atom board/cpu combo, and 1 GB of RAM for it.  Not too much cost to expand its use greatly, but if you were starting from scratch it might be a big investment.  So give it a try with your old garage PC first.  I paired the computer with a 23” Samsung 2333HD Display, which is kind of a misnomer.  The actual NAS is capable of displaying a typical Unix/bsd console, but it’s really meant to run in a corner or a closet without a keyboard or monitor hooked up.  In fact, there is no GUI display included.  The monitor is really displaying video from my macbook pro, which makes the computer give the appearance of a hackintosh.  It’s also a nice 1080p HDTV.  The actual Atom computer runs without being plugged into the monitor, unless I’m debugging something.

So I spent all this money getting decent hardware, at least the software was free!  You’ll need to decide between a “full install” or “embedded” install.  The full install is like a typical OS installed onto your disk.  The embedded install is copied to a USB Flash Drive which is then booted off of, and it runs FreeNAS in a virtual disk created out of RAM.  The full install is easier to customize, but the embedded install is blistering fast and allows your hard drives to spin down when idle.  I went with the embedded because it’s very important to me for the idle disks to spin down.  This saves wear and tear, heat (remember it’s fanless), and power ($).  You can’t repartition the boot drive, so I had to add another flash drive to run my custom server apps like rssdler and python.  Running these apps off the main data HDDs would prevent them from spinning down (they’d never be idle).  Flash drives are cheap SSDs and it works great for NAS purposes.

After the initial console setup, you can unplug the monitor and control the system via a web interface on any other computer on the network.  This makes it very easy to choose services, set them up, add disks and shares… You really don’t have to be a pro to get it to work reliable and consistently.  I followed a tutorial, added my two hard drives as a redundant software RAID 1 array[Edit 11/30/10: This has changed, see: FreeNAS Update: Rsync and Unison], and added windows and apple file sharing in less than 20 minutes.  Performance was a ten-fold increase over my Linksys NAS, averaging about 40MB/s transfers which I’m guessing is limited by gigabit ethernet.  But don’t take my word for it, here’s some fancy looking pictures:

Linksys                        vs.                          FreeNAS

My Atom server blows away any of my previous NAS attempts, and I’m finally happy and able to not worry anymore about my hard disks crashing and taking all my stuff with them like the great hard drive crashes of 2003.  It’s far quieter and faster than the Linksys NAS, and I can run apps like rssdler off the server alone.  This means the AppleTV, which is already slow, doesn’t have to use its few resources on downloading for me anymore.  It uses waay less power than my gaming pc did when it stayed on to serve files, and adds the redundancy of two drives, protecting against hardware failure.  The loss of one hard drive wouldn’t make me lose any data.  The web interface is easy to use, and since it’s a mini-atx form factor, it’s got plenty of room for additional hard drive space so I can expand it over time.  The Linksys and many other NAS devices only support a maximum of two disks.  And did I mention how quiet it is?

The only disadvantages I could think of was the additional cost for having an additional computer.  If you have an old PC and could throw it in the closet or something, this disadvantage may not mean much for you.  Also, the mini-atx form factor eats up some desk space for me, but I want to keep it close to my other computers.  Again if you threw it in a closet you might not care.  I’m decent enough with Linux/Unix/bsd commands that I didn’t have any trouble setting it up, but if you’re a windows lover then buying a commercial NAS might be up your alley. 

So in summary, I am totally blown away by FreeNAS and all it’s capable of.  I tried everything else, but sometimes when you need the job done right you just have to do it yourself.  My next tech post will probably be about AT&T U-Verse, how it’s integrated into my new house, changed my network, and reacted to my experiments.

Linksys NAS 200 Review

I’ve made several posts about my TV setup, and making improvements to the little home theater is a growing hobby of mine.  Most of my recent posts have revolved around hacking the AppleTV, but it’s only part of the setup.  If the AppleTV has nothing to play, then what’s the point?  Until recently I never much cared for TV.  I mostly just used my computer to watch TV (tuner card), play DVDs, collect anime, movies, shows, etc..  But when we got the LCD TV and I started streaming all my stuff through the PS3 to display it on the big screen, I knew I could make it really cool.  There were a few problems with that setup though.  My computer had to be on, which ate up power.  I had to run the Tversity service which was hard to update and slowed down my computer.  The PS3 made a lot of noise, and couldn’t play everything I had saved.  The AppleTV solved the PS3’s problems, but in order to store all my content, I’ve been going between different setups.  My first attempt was an external USB HDD plugged into the USB port on my Apple router.  The router acts as a NAS server and shares the drive across the network.  This worked great for a while and is certainly a cheap and easy solution, but the hard drive crashed twice taking all my data with it.  Luckily most of it was still backed up on my computer.  Not sure if the drive or the router was to fault, I decided to buy a second hard drive and the Linksys NAS 200 to fit my needs.  Will it work out?

The first thing I like about the Linksys NAS 200 is its compact design.  It looks pretty similar to a linksys router, but sitting on top of two hard drive bays.  Installation of the two SATA drives was pretty simple, just push them all the way back.  Pulling on a ribbon will pull the drives free again.  You plug in the power, plug in the cat5 cable, and you’re done with the physical setup. 

The software that powers the device is alright.  It does the job as a NAS, but you get the feeling that something like this would be capable of so much more.  The NAS 200 will spin down the hard drives when they are not being used, which saves power, wear and tear, and heat from building up in its idle time.  I have a feeling this was what lead to failure when I used the USB enclosure.  When data is requested from the NAS server, it spins up the drive and fans help keep them cool, prolonging each hard drive’s life.  The number one reason I looked into a device like this was the dual hard drive bays supporting RAID 1 (Mirroring).  The NAS 200 can be setup to make an exact copy of the first hard drive onto the second so if one dies, you won’t lose data.  Alternatively, you can double up on hard drives for more space.  Other than a long wait for it to duplicate the disk, it was easy to setup and a load off my mind.

The NAS 200 uses samba, or windows file sharing, which is pretty much standard among home networks.  It was very simple to get the AppleTV and other computers to access data, and I was able to get Windows 7 Ultimate to backup to the drive pretty easily.  It also features a web interface, giving you the possibility of accessing your files remotely (like from work).  My upload speeds are way too horrific to give this a try.  It can download files for you, letting you turn your computer off, but it’s HTTP instead of bittorrent which is not as useful.

Things I do not like about the Linksys NAS 200 are numerous.  My first complaint is one I read before I bought it, so I knew going in.  It’s slow.  Like, it’s floppy drive slow.  The NIC on it is a 10/100 mbps speed, which..come on…we’ve had gigabit for almost a decade already…  On a device meant to handle large amounts of data, the speed at which it’s done is atrocious.  I have about 1 TB of content, and copying it all to the NAS 200 took over 3 days!  It’s so slow that windows has to put up a progress bar when renaming files.  Mirroring the hard drive took forever, and the web interface is slow.  It’s rocking a 486 processor inside, which probably runs hotter and slower than more recent even cheaper processors.  It’s irritatingly slow, and I’m surprised I held off for several paragraphs before blurting that out.  My graphing calculator could probably serve files faster than this. 

It’s also loud as shit.  Computer noise is starting to annoy me more and more.  With its fans running, I can hear it from anywhere in the apartment, and even over my gaming PC which sits right next to me.  I’m glad those fans are there to save my hard drives from heat death, but not if it makes my ears bleed. 

Those are really the only two bad things about it, but it’s enough to make me want to get rid of it.  If you are planning to hide the device in an attic, or somewhere you wouldn’t be exposed to its noise then it could be a good buy.  But you’d also have to have a jurassic-era 100base-t network and running pentium pro computers to not notice how freaking slow it is.  The only thing it has going for it, is that it’s cheaper than most of its competition.  It’s a cheap device and you get what you pay for.

Deciding to spend the little extra to get what I want, I’ve recently built a micro-ATX 1.66Ghz Atom server and successfully installed FreeNAS.  I’m hoping to have the configuration done by Thursday, which will be detailed in the next tech post.

Proper Magic Mousing

Alison got me one of the new "Magic Mouse" mice from Apple for Christmas, although I just got it yesterday. They were readily available for about a week after they were announced, and then they were gone. It's taken forever to find one actually in stock. It's the first time I've actually been excited about a mouse from Apple. Always trying to reinvent it with each iteration, it's always seemed like a better idea just to buy a $10 usb mouse and sell the ones they come with for profit. So I was pretty skeptical when the Magic Mouse was released. Apple is all about the multi-touch tech these days and it surprisingly kicks a lot of ass. Like its predecessors, its "virtual buttons" make it not ideal for gaming but most of the time my Macbook Pro sits in the corner of my desk, and having a nice bluetooth mouse will make casual web browsing and OS use easier.

Like all Apple mice, it gets a lot of hate from people who haven't used it or are using it wrong, so I thought I'd take some pictures of its proper use. There are two types of mice it seems: the big "palm" mice like the microsoft intellimouse of a few years ago, and "finger" mice like my favorite Razer Copperhead. With palm mice, you rest your hand over the mouse and move your arm at the shoulder to move the mouse around. Finger mice are for those who keep their arm stationary and move the mouse with wrist movements. I'd definately put myself in the finger mouse camp. I hate big mice. So if you're like me, you'd probably like the Magic Mouse too.

	Here's a view of the Magic Mouse surrounded by my other two mice, the Logitech G5 (left) and the Razer Copperhead (Right). As you can see, the mouse is a little smaller than the other two, but not by much. The whole surface of the mouse is like a giant touchpad, and simply moving your finger up and down the mouse acts like a scroll wheel. I had to put them on a box since my desk is black and so are the other mice :D
It's hard to show just how thin the Magic Mouse is. Pic on the left is the MM in front of my old Razer Copperhead. The MM is about half the height of my already thin finger mouse. The G5 is more of a palm mouse so it's bigger, and the picture on the right shows the MM about 1/3 the height. The MM is wide and thin, made well of aluminum with a plastic top. Feels nice and sturdy. Not too heavy to move around, yet it stays in place when gliding your finger(s) over the surface.
	Here's me holding the Magic Mouse incorrectly, like a palm mouse. When you hold it this way, your fingers don't have any room to scroll up or down, and the bottom corners of the mouse dig into your palm a little. So when you hear people complain about its sharpness, you know they are holding it wrong.
Here's how you actually hold it, thumb and ring finger on the middle of the mouse, where it's tallest. Your index finger should be right in the middle of the mouse and free to move all the way up or down, making scrolling a dream. It's so much nicer than a scroll wheel, and if you like the two finger scrolling features macs have, this feels just like it, and maybe a touch better.
