5 out of 5 eggs"I like it alot" (said in Jim Carry's voice)

Pros: -Easy to install and setup
-Great price (I picked it up @ $199 CAN)
-Good build quality
-Good packaging

Cons: -No hardware RAID

Other Thoughts: I installed the included PCI-e external SATA card into my home file server running Windows Server 2008 R2. The drivers from the included CD installed easily without any problems.

I did not bother install the software utility. I only installed the device driver for the PCI-e SATA card. I use it in its regular JBOD mode (Each hard disk drive has its own drive letter in Windows).

5 out of 5 eggsWorks Great!

Pros: JBOD works just as it should with provided PCI-e card.
Performance is what I hoped for, plug-n-play is great also. Install took about 5 minutes. Just had windows 7 look for the driver from the disc, without installing any software (JBOD only)

It also looks great next to my Antec 900, they have a matching look.

The construction is good, including the paint. The sides & top were covered with a protective film to protect from scratches.
It was also packed extremely well from the factory. It had a thick bubble pack around the sides, and double boxed for more protection.

Cons: no cons!

Other Thoughts: I should have bought one of these before buying all the single external enclosures that I now have laying around.

5 out of 5 eggs

Pros: Price and speed ..I bought this to house my ever growing collection of media files . I had been cramming all my hard drives either in my PC tower or in a HD dock. I knew at some point I would need to step my storage game up. I bought this and planned to use it as JBOD... I already have a raid 0 with raptors and SSD's still in my pc tower. When it arrived and I opened the box , it had the best packaging I've ever was wrapped in like a air bag on all sides. Hardware and software was a breeze on this win7 64bit box. I put 4 hd's various sizes in it to start. and ran some benchies because I heard it was slow. Running HD tune pro I feel I got the full speed of the drives measured by the included controller card. WD 640GB (91MB/s avg..), WD 1TB (82MB/s avg ) , SAMSUNG 1.5TB (83MB/s avg ) , SAMSUNG 500 GB ( 64MB/s avg ) . And since my raptors are still in the pc case , I decided to transfer a 4.5GB MKV file to the Sans tower... the file took from 39 sec to 55 sec

Cons: depending on the hard drive. I would not hesitate to buy one of these again..It has a huge fan and is pretty quiet. It has some plastic parts mixed in with the metal , but it's constructed very well. I have not tried the raid software and don't intend to . It

Other Thoughts: This was a great buy for me.. after putting it in the cart a half dozen times over several weeks , it was time to man up.. just like the commercial

5 out of 5 eggsNice unit

Pros: - Simple to setup
- Supports 8 drives
- Painless

Overall it has worked flawlessly. The included card isn't a high performer, but works. I did connect mine to my RocketRaid 2314 and it works perfectly, even with a variety of new drives, including the WD. Not sure why it wouldn't play nice. Does in my setup.

I'm about to buy a second one to replace a 5 drive unit. Both are connected to my Windows Home Server setup.

Cons: None that I have found.

4 out of 5 eggsGreat little enclosure

Pros: Compact size. Not a flashy style (other than the blue LED, which you can find a way to disable if you really want to). The front pieces on the drive bays feel and look a little cheap, but you can't really see them with the door closed, and the functionality is actually very good. The hot-swap bays line up and secure nicely.

Cons: There is a white logo on the top which is kind of annoying and which is not on the other enclosure that looks otherwise identical and is sold under a different brand name. he logo was not easily noticeable on the pictures. But this particular enclosure was part of a combo deal that saved me some money on a disk, so I can deal with the logo.

Other Thoughts: A couple of other reviewers recommended pairing this with the Rocketraid 2314 instead of the included card. I DO NOT recommend that. The Highpoint RocketRAID card does not play nicely with certain Western Digital drives (including WD1001FALS). (For more info, please see my review on that product's page.) The included card works pretty well. It works out of the box with Ubuntu & Windows XP (haven't tested any others). Depending on your RAID configuration, I think you're more likely to be limited by the drives and by the limits of SATA II than by the limits of the included controller card. Furthermore, many of the newer motherboards are coming out with port multiplier functionality on their onboard eSATA port(s), so you can plug the enclosure right into your motherboard.

4 out of 5 eggsGood Unit Overall

Pros: Inexpensive considering it's an 8-bay unit, decent air flow keeping the drives cool, easy set up, nice looking case.

Cons: The unit came shipped with one of the molex connectors unattached -- easy fix, but you should open your case before powering the unit on to make sure everything is intact.

The supplied SATA cables do not lock into place, which means that if you move your case around, there is a possibility of the cables popping out without much effort. This is probably my biggest complaint. I don't know if I can buy locking SATA cables to replace these with?

Other Thoughts: The drive light placement on this unit are completely non intuitive. They all sit on the bottom left of the unit away from the actual drives. When I first installed my hard drives, I went from top-down, however this was backwards. Drive 1 is at the bottom of the unit, so install them bottom-up if you're not fully populating the unit like I did.

Like a previous reviewer, I don't understand why the power light is orange. I was completely expecting it to turn green once the unit was connected to the server. It simply looks like it's in standby mode all.

The drives will not power up until you have connected everything properly and started the server. I was worried at first because none of my drives had power, however that changed after hooking everything up. This is good, because I can shut the server down and the drives will power down with them. The case fans will stay on as long as you have the power supply switch on -- not the best design, but it's at least low power consuming.

4 out of 5 eggsSANS TR8M-B

Pros: Cost effective raid solution. Working great for my needs.

Cons: Controller that comes with it was DOA, and only supports software RAID. Controller that comes with it only supports up to 5 drives in one RAID config.

Other Thoughts: I called tech support, got right through, after talking with tech he sold me on a new a new controller RocketRAID 2314 (hardware raid). I purchased 8 1.5TB drives, and have it configured in one RAID 5 with online hot spare.

5 out of 5 eggsSo far completely sutisfied

Pros: Fits 16 TB. Need only one powercord and 2 eSata cables to access 8 separate HDDs. Ability to cool HDDs independently from the main system.
Small sized box - looks like a miniTower.
Sturdy steel material.
100% Windows 7 Compatible - takes up to 5 minutes to have it all set up and going. I actually took a hard drive out of the external enclosure I bought a year ago and just popped right into the TowerRaid. Worked like a charm. Was a little worried when some people said it has Windows 7 compatability issues, but now I understand why they said so - they should really read the manual for product installation.

Cons: Don't know of any yet ... If anything comes up I will write about it.

Other Thoughts: Haven't played with SATARAID 5 (array manager) yet - Windows GUI presents options to create various RAID configurations.
Don't know how it handles SSDs.

2 out of 5 eggsWorks Great When it works... My 2nd failed enclosure

Pros: Inexpensive

Cons: I had to send in my first one for warranty repair. All the drive bays quite working. Now just the top bay is no longer recognized and the controller is acting odd on the other drives.

5 out of 5 eggssolid product

Pros: holds eight drives and does what it's designed to do.

Cons: I would probably prefer two fans vs. the one large one, but I can't really call that a con.

Other Thoughts: Someone mentioned that the drive bays didn't have locking mechanisms, but mine do and they work as expected
