TowerRAID TR8M+B - Eight-Bay eSATA RAID 0 / 1 / 10 / 5 / JBOD Performance Tower with 6G PCIe Card

The TowerRAID TR8M+B is a compact RAID tower utilizing the latest SATA port multiplier feature, where one single eSATA cable connects to eight SATA hard drives. Bundled with a high-performance PCIe 2.0 x1 RAID controller card RR622, its RAID 5 performance is capable of reaching over 250MBps. Online expansion is a feature included in the controller card so that RAID could be expanded without the need to recreate the storage space or erase the existing data. Advanced monitoring functions include real time hard drives health status and e-mail notification for critical events.

Designed with easy installation in mind, the TR8M+B is designed with eight hot-swappable tray modules so that hard drives could be removed and installed with ease. The included dual-port eSATA 6Gbps PCIe 2.0 x1 RAID controller card allows the connection of eight hard drives using only two cables, while all drives could be configured into single or multiple RAID arrays, providing over 200Mbps in performance.

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

1 out of 5 eggsI just carried it to the dumpster

Pros: Nice appearance. Easy drive access.

Cons: It doesn't work. I loaded it with 8 4TB WD Red drives and all it ever did was complain about them failing. They test fine in computers.
I called Rosewill and they suggest I wiggle the connectors and buy all new drives.
I just carried it to the dumpster after a year of wrestling.

Other Thoughts: Forget the whole ESata idea. Hook directly to your network via gigabit or if you don't have a network, use USB 3.0
ESata was a good idea whose time never came.

2 out of 5 eggsBeware of the included raid card!!!

Pros: The enclosure might be fine?

Cons: The included PCIe card is a significant detriment to the performance of my 4.8 GHz 6-core watercooled monstroscity of a computer. It locks up my computer for a few seconds of every minute after trying to write ANYTHING to it.

Other Thoughts: San Disk ought to ship this enclosure with one of their own cards. The included HPT RocketRaid 622 is a sad excuse for a raid controller.

I'm excited to see if a "SANS DIGITAL HA-DAT-4ESPCIE" that I just ordered will allow me to push the envelope of my 8-bay raid box...

2 out of 5 eggsnothing but fail

Pros: came with newegg gift card

Cons: bought this on july and didn't function properly since. top 4 bays would fail constantly. every time when I'm about to access (read/write) one of the drives on top 4 bays, it crashes. it power cycles and tries to boot it back up, but doesn't detect top 4 drives afterwards.

I thought ESATA cable was faulty since it does look cheap. order two extra ESATA cables but same problem. began to look at other parts for troubleshoot, naturally I assumed it was the RAID card that came with so I ordered different RAID controller but same problems. Then I suspected my HDD wasn't healthy. I have all WD from 1TB to 2TB making up total 11TB on it, so I began to run HDD check with WD diagnostic tools, all passed.
Just in case, I rotated HDD around on different 8 bays on it. no matter what type of HDD I put on top 4 bays, it crashes. so that's that. I've concluded that tower is having trouble so I RMA'ed the thing. When I received the 2nd times, it was having a same problem. always that top 4 bays.

I've tried with 3 different workstations from WHS 2003 to windows 7, and 8 environment.

Other Thoughts: Tech support and RMA department representatives are superb. very quality service and knowledgeable. too bad they have to suffer on poor devices. very disappointed on Sans Digital..
