So I bought one of these:

it's an esata raid box.
I'm not much interested in RAID 5. what I want is RAID 1 which is mirroring. I also want speed which my NAS server wasn't giving me.
I picked up four 2 TB Samsung drives and set up two RAID 1 mirrors. The tower came with a host card with two eSata ports. The RAID is software based. I was a little worried about performance but its more than fast enough as a media server. You could always buy a dedicated raid card if you wanted.
A few comments on the hardware:
It's a Sans Digital Toweraid TR8M-B. There is a newer version TR8M-BP if you want a better card thrown in for 319.00 via Newegg.

I picked up the TR8M-B for 279.00 at my local Fry's. (the four 2TB Samsung drives were 79.00 each)

BTW, all hard drives/brands have tons of comments about bad ones. Besides drives that are DOA or die quickly, these Samsung HDs have the least complaints. The last HD to die on me was a Western Digital 750GB.
Drivers and documentation are crap. In fact, it came with the wrong drivers. I got the drivers for the card that comes with the TR8M-BP. After figuring this out, I grabbed the drivers and browser based GUI RAID Management Software off the web.
I was concerned about noise, and also build quality for something like this. Well this box is high quality. It was packed extremely well...annoyingly well. The box was lined with air bubble tubing, the case itself was in a bag, and then the case was coated in protective plastic which took forever to get off.
There's one large fan in the back. The entire front is a grill as well as two thin grills on the sides. Lighting choices on this thing are odd. For some reason, the back fan is lit up with blue LEDS...huh? There appears to be absolutely no reason for this. Even nerds aren't going to be looking at the back of their case. The power button lights up orange instead of green which just seems to go away from your standard green for on. The eight LEDs for the Hard Drive bays are good. Green if there's a recognized drive in the bay and orange when there's activity. As it should be, both mirrored drives light up orange when in use.
Now for the important part. This case is super quiet. I have an Antec P180 case which is very quiet and this case is even quieter. I was pleasantly surprised as I thought for sure my decibel level would go up with this. The one large fan pumps a lot of air. I researched all the 2 TB hard drives and the SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM drives came out the winner for reliability and quietness. They also perform well. After popping four of them into the case, I can't hear shit from the case.
The hard drive trays work well. You do need to screw your HDs onto the tray but the locking system works well and there's no cables involved.
Time will tell how well the TowerRaid and hard drives hold up. I've already transferred over some monster files (a few single files over 250 GB in size each) with no trouble and good transfer speeds. I checked the drive temperatures after transferring over about 500 GB and they remained nice and cool. They only seemed to vary less than 5 degrees F between idle and max load.
I counted up 13+ TB of storage space I have. This tower thingy alone can handle 16GB (or 24 TB with 3TB drives and other raid card). I'm just going to mirror everything so will eventually get 4 more 2TB drives.
Some of you may prefer RAID 5 or other. I have enough storage space now. I prefer mirroring so I can grab a HD and go if need to or quit RAID altogether and have my drives usable in non raid mode.
Some of you may recall me posting about other storage stuff I've picked up in the past. I have the original Buffalo Terastation NAS. It cost me 1000.00 for 4X250GB drives for a whopping 1TB. I picked up a 2 Drive LG-NAS that has a Blu Ray burner built into it. That thing is also whisper quiet. Turns out I don't like burning Blu Rays even for data storage! I also bought a 4 HD Hotswappable tray system for my PC which I still have in my Antec P180. I have a couple HDs in there but the thing was really loud with two cheapo mini fans in the back. The fans burned out. I'm running my OS off a 128 GB Corsair SSD.
I think this TowerRaid 8 Bay Case has the capacity to keep me happy and mirror secured so I can start to fade out some of my other HDs and servers. My main PC is always on so having a dedicated NAS box isn't that big a deal although I have 4 TB if needed in my LG-NAS. I can always access my main PC as a server. Having the RAID software based should also help for portability of the Towerraid.
