4 out of 5 eggsWorks with Linux perfectly as a pass through port multiplier

Pros: The included PCIe card works well with Linux as a pass through port multiplier. Smartmon tools work with all connected drives. Not sure if the built in raid would work or not haven't tried it. Software to configure it is Windows/Mac only. I'm using it with ZFS so I was only interested in pass through functionality. I haven't actually tested performance but I know it can saturate my 1GB lan so it's fast enough.

Cons: Fan is a little loud but not enough for me to lower the rating.

3 out of 5 eggsHot and pretty

Pros: A pretty box with hot swappable drives and good customer service. I had no problem getting technical support on the phone.

Cons: It gets hot, really hot. I purchased this knowing that 8 hot hard drives in a small box like this with a single cooling fan would present problems.

Other Thoughts: I thought I would not use the box very frequently or for long hours but I was wrong and this is the reason I took off only two eggs. It turns out that when drives restore redundancy or rebuild raid groups it takes several hours to complete, in my case 60-90 hours. I run three RAID1 groups with 2-TB drives and one RAID-1 with 3-TB drives, all WD Red. I use CrystalDiskInfo to monitor the temperature. Unfortunately I live in Houston and the drives get hot with an average temperature inside the house between 76-78 Deg. F in the summer . There is no way to add fans to the box but when I removed the left side panel and placed a fan to blow air directly to the drive cage it still got hot. I shut it down when CystalDisk indicated 50 and 53 deg. C. This is a pretty box but I can only use it in the winter time. Now you know why I gave it the title "hot and pretty".

1 out of 5 eggsUnreliable!

Pros: has 8 bays and cheap when it works I've even gotten some really good transfer rates

Cons: constantly has Ultra DMA CRC Error counts, which eventually get bad enough where the channel is reset by the driver lights blink and it trys again eventually OS reports enough drives failed to where the whole array fails (some times works for a few weeks with no issues other times craps out in minutes or even at boot just constantly resets and my fileserver cant even get started). Ive tried 3 different eSATA cards with it the one it comes with RR622, HA-SAN-2ESPCIE2, and then i even spent the money on a HA-DAT-4ESPCIE also has the same old problems. been working with tech support for months with no resolution or even anything new to try. save you money any buy something that actually works this is too good to be true, and based on other reviews my experience is not unique although tech support would have you believe that is not the case.

Other Thoughts: I have my drives set up for JBOD on the card and I'm running CentOS 6 using MDADM to create a software raid 5 array that has one large EXT4 partition and using samba to share it out over a very small home network. tried hardware raid as well similar poor results.

also one of the many hats I wear during the day is system administrator and i have other software and hardware raid arrays i have set up over the years with windows and Linux and even MDADM software raid that are working flawlessly and have been for many years so its not like I don't know what I'm doing.

1 out of 5 eggsWatch out!

Pros: Compact, large, great price

Cons: The fan on this thing is prone to give out. Mine lasted a little over a year. Once the fan went out, my hard drives were BURNING HOT to the touch. I removed the side of the enclosure, which should probably be done regardless. My power supply has been pretty good up until now, so hopefully there isn't any permanent damage done.

Other Thoughts: For the amount of money this thing costs, it's probably best to look elsewhere.

3 out of 5 eggsGreat when it works

Pros: 8 Bays
Hot swappable

Cons: Reliability
Power supply is garbage.

Other Thoughts: This thing worked great in the beginning. Then after about 2 or 3 weeks drives started dropping and the raid array would fail rebuilding with random drives. The drives would test just fine in another computer. Put them back in and they would fail saying bad sectors.

Then I got a spare ATX 400W and connected the molex connectors to the backplane. It ran great, array would rebuild with no drive failures. I have a 350W matx PSU on order.

If you want performance, don't bother with the 622 card. The 642 cards performance is pretty good. I was able to get real world write speeds of around 180MB/s in RAID5. Also the 642 card supports RAID50 as the 622 doesn't.

1 out of 5 eggsWaste of Money and Time

Pros: Seems like a good solution

Cons: After acquiring this item I placed 3 4TB WD Green drives into the enclosure. I installed the RAID card on my media center. For the first few months everything was fine.

All of a sudden one day Windows stopped booting. Upon closer inspection I discovered that the enclosure would simply shut down the drives randomly during start up. The activity lights for all 3 drives would just turn off in the middle of boot up. I thought maybe I could try a different bay so I moved them to the lower bays in the enclosure. I also tried replacing the eSATA cables to no avail. The eSATA ports are not engineered properly either since the eSATA cables don't fit entirely into the port leaving about 2-3 millimeters of extra space.

I contacted Sans Digital support many months ago about this issue however their representative blamed my hard drives which are in perfect health. Apparently I need to be using the more expensive enterprise hard drives instead of my consumer ones. Of course he couldn't explain why my existing hard drives worked for so long with no problems.

The RAID card itself slows down the boot process considerably.

Do yourself a favor and stay away from this product.

Other Thoughts: I find it peculiar that a support representative would recommend using enterprise drives for an entry level product. If I'm gonna spend the extra money on better drives I'm probably also going to spend the extra money on a better enclosure and RAID controller.

1 out of 5 eggsA waste of money

Pros: Price. It's the cheapest 8-bay enclosure around.

Cons: Simply doesn't work as intended. The raid cards fail and the bandwidth is poor. The drivers are poor, and you can't make it work without the proprietary PCIe card. It failed so many times in the course of trying to use this solution for 1 year (even after replacing multiple raid cards and cables), I had to scrap it and just buy a better enclosure (which has since worked flawlessly). So I lost $400 on this bad hardware.

Other Thoughts: If you need 8 bays, buy two 4-bay USB3 enclosures and call it a day.

2 out of 5 eggsBeware the heat and the power supply

Pros: Simple setup
Dual-channel
Small Form Factor
Cheap
RAID recovery is priceless

Cons: RAID card support is fun to deal with but once you get used to the site, youll manage
Might catch fire
Wonky Power Supply
Runs super hot
Doesn't really seem like 6G...

Other Thoughts: Been working good enough for the last couple years, but man, when it goes, it GOES. The power supply went on the fritz and started smoking really bad. Fortunately, the power supply was the only thing harmed. I bought a $20 AT 300w to power the Constellations in there... Thing runs HOT and the big fan looks impressive, but I don't think it really does a lot of cooling. There doesn't appear to be good channeling of air in there. Might want to consider leaving the door open. For what it is, it's a cheap enclosure. The HighPoint RAID tools allowed me to get the thing back online quickly to make a bare-metal backup... Now I will see what else I can get to hold my users' home folders.
It doesn't seem as fast as it should be either.

1 out of 5 eggs

Pros: looks nice --None does not work with win 7- 64.

Cons: cables do not lock in bad quality/design. Can get array built in bios but every time i go to windows and try to format the unit crashes. Searched and found updates but that made it worse. pclink 2 kept dropping out when Windows starts. Tried to call tech support but you get voice mail and they didnt call back.
spent too many hours as it is. Bought Areca raid card for 8 drives and ripped out boards so it just holds and powers the drives.

Other Thoughts: Do'nt try to do raid with a rocket raid 622 card.

5 out of 5 eggsAmazing product

Pros: 8 Bay
Bundled Raid Card (Software)
Superb Air Flow
Long Life
Well priced

I've used this Tower for 4 years now and it has been a superb product. There are many negative reviews, but I have not had any significant issues. I use a raid 5 setup using all 8 bays. All of the drives are 2TB bargain specials which gives me 12 TB of usable space and a spare drive in case of failure. Now into year 4 the fans have been replaced as the power supply fan started to make noise and the other only made since while I was in there; the only time I was in there.
The bundled card is not amazing, but its functional. It's only pci-e 2.0 x1 and that's not enough bandwidth for this tower. Pair that with the difficulties caused by software raid I can see why people trying to use this on a less robust system might have run into serious trouble. I went with the RR642; it's still software RAID, but the x4 bandwidth helps a lot.

Cons: None
It does what supposed to do all day everyday for going on a half decade.
Not USB 3.0 Compatible

Other Thoughts: I might suggest a USB 3 device to someone getting a hard disk tower today; but I have been superbly satisfied with this purchase
