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.

5 out of 5 eggsWorks-excellent customer service

Pros: Working well since 2012.
Customer service responded promptly and professionally to questions e-mailed in 214.

Cons: None

Other Thoughts: I had four 2 TB WD disks, arranged as two Raid 1 arrays in the lower four bays of this unit since 2012. I have had no problems. A month ago I decide to add two 4TB WD disks as yet one more Raid 1 array, and a 1.5 TB refurbished SeaGate drive as a trash file holder. The eSATA controller on my MoBO did not detect the additional disks. I asked for advice from the SansDigital Customer Support and was able to get a workaround promptly. These folks do stand behind thir product and help their customers.

4 out of 5 eggsWorks for Home Use

Pros: Has worked as a Raid5 server since 2010. I have used the Online Expansion twice and reconstruction for drive faults three times (14-24 hour rebuilds each). Removed drive cage from enclosure and installed in mid case w/ u-ATX mobo and fanless PSU for a quiet home server and backup.

Cons: Can not write more than 20 GB at a time without transfer slowing to KB/s and Windows 7 locking up unless transfer is canceled quickly. Drives can get over 110 *F when operating for extended periods unless active cooling is applied. RR622 was troublesome to setup but driver updates and fiddling got it to work after a few false builds.

Other Thoughts: 5 then 7 then 8 Samsung EcoGreen F4 2TB drives installed. Read speed of 120+ MB/s, Write speed of 60-90 MB/s. Drive spin up could take 10+ seconds but once up, instant access. Will buy again with a better RAID card or the TR8M6G . Will also get better drives with vibration sensors/resistance.

3 out of 5 eggsSans Digital Really?

Pros: Sturdy case with very easy to use hard drive trays. Trays lock in with minimal effort. Front lights are blast to watch and wish my SATA/SAS case used the same all green/flashing red when accessed scheme. 2 eSATA ports the work flawlessly with my ASUS eSATA, found all 8 drives without a hiccup. Basically a great home for my Red WD drives. But has no running water, sewer or electricity.

Cons: Tried to use the packaged Highpoint 622 card. Now I am probably alone in the Highpoint fan club as I have run a 4321 and a 4311 card in my system for the last year and a half without a problem, however the 622 is another story. I have read about problems using the card and just figured it was the systems fault or OS but that is not the case. Unless you have a MB that uses Port Multiplier eSATA ports don't buy this. The 622 can't keep up with the demands of an 4 drive array and forget 8 drives. Timeout, stop, stall, waiting system not responding.

Other Thoughts: Ok bashing over Sans Digital made a great case for what I needed the 622 was an experiment and I never really intended on using the card, but for those who need the card buy something else like the Sans Digital eSATA,1394B, usb 3.0 Raid 4 drive cages. This product is just a good home for the drives you have to come up with the connection to your system.

1 out of 5 eggsMonths later... It was not the hard drives

Pros: Cheap and has lots of drives, and its SATA3!

Cons: Constantly crashes over and over and over and over again. Basically when you read or write data to either a single drive or a Raid array and you look at it the wrong way it ends up basically power cycling the bay (top or bottom 4 drives) that triggered the issue. It will continue to do this (btw you computer locks up on you doe 1 second repeating every 3 to 5 seconds over and over till the write cache is emptied). Also this all causes your system to BSOD if it really does not like what your doing.

I am using 3TB WD RED drives, I started with 4, but with all these problems i thought i had drives with bad sectors (btw never use a usb to SATA cable to run diag tools on a drive). but after 2 drive replacements and still having the issue (the drives were never the problem i just got bad readings) i ended up buying 2 more drives and removing 1 of the 4 RAID 5 drives in order to pull off all the data onto each drive individually.

BTW every time i rebuild the array that was 27 hours when dealing with a 4 drive 9TB(12tb) RAID 5. Also when it checks the drives consistency and it did its little crash it freaked out and thought one of the drives was bad (and it probably was not) and then you had 27 hours where you basically can't touch the drives while they rebuild or they will crash

Currently have i have 6 drives in this all running in the Legacy setup, with no RAID, this way i have 3 drives on the top and 3 on the bottom, so when it crashes i am not interrupting stuff running on the other drives... sigh

So one option is to get a different eSATA card, but honestly looking at any of the ones offering 2 external eSATA ports, i don't see any that look all that good, also there is nothing to say that the board's in the tower are not the issue.

I have played with caching on both the management tool and in the OS, also used tools like TeraCopy to better manage copying to the drives (needed to do this because of all the issues with copying files to the drives)

Other Thoughts: I think your best option is to suck it up and buy a real card, spend the 200 to 300 to get a real SATA/SAS card with those fancy breakout cables, and use that in a tower that has some extra drive bays.

1 out of 5 eggsGood only for minimal I/O

Pros: Cheap, nice design, easy access to drives

Cons: began failing with a blur screen after 2-3 months.

At first the drive worked great, however, as the I/O traffic began increasing the unit started failing. First, it would freeze while accessing the drive and you could see the light blink, then it would turn off access to all of the drives, cycle through them and restart the I/O. This would also freeze Windows for the cycling period (Windows 7 prof)

About 3 months after the purchase, then unit would just crash with blue screen. Once the computer gets to BIOS, it would not even see any of the drives. Occasionally, it would find one or two out of 8. Sometimes I had the whole system unplugged from the power and it would start working again, but then eventually fail. First I thought than it might be the PCI card, but then I opened the unit and discovered that the drives and unit chips are very hot!

Not sure what I will do about it. I have about 12 TB on it and can only access 4 or 6 TB at best.

Other Thoughts: I will see if the fan could be switched for a better one or maybe just shoving another one in the back. In any case: if u plan on using the storage for heavy traffic (such as a media storage) stay away.

5 out of 5 eggsGreat Product And Excellent Customer Service From Manufacturer

Pros: Super fast. I get burst rates from a drive within the tower to my system drive around 150 MB/sec. Sustained transfer rates are about 110 to 115 MB/sec. Drive to drive transfer when both drives are in the tower is slightly slower - burst of a about 135 to 140 MB/sec and sustained rates of about 100 MB/sec.

Amazing JBOD solution. Excellent custom service from Sans Digital (see Other Thoughts below).

I also love that the card comes with a low profile bracket. My HTPC is a slim case and I currently have it hooked up to that.

Cons: Not a whole lot. Cables that came with the product could be longer.

Also, this isn't a "true" hardware RAID card. That being said, I can't comment on the RAID capability of the card as I used the JBOD-only drivers after other reviewers scared me about the allegedly problematic RAID drivers causing data loss. I was never a fan of RAID anyway for exactly these reasons. Seems to easy to mess up or have a problem that bricks the array. But I can't fault this card for that given its price tag.

Other Thoughts: This tower is a fantastic value. I didn't want some unjustifiably expensive solution for my backup needs. This was the perfect solution. This device is perfect for a JBOD setup for backup or other mass storage.

My wife accidentally threw out the instruction manual, driver disc, and extra bracket, cable, etc. I called Sans Digital and they went out of their way to look up the specific items I was missing and they shipped them to me (except for the cable) free of charge! They also had someone upload the entire driver disc (with the instruction manuals included) to a file sharing website for me to download. I was truly impressed with their customer service team.

1 out of 5 eggsDOA

Pros: Can't tell. Doesn't work.

Cons: We purchased this for data storage in our lab. We plugged in 4x4TB WD Enterprise drives in the bottom 4 slots. We installed the PCI-E card and then plugged the tower (both cables) into the card. When the tower started up. The PC Link 1 and 2 lights lit up in addition to the power light. The light for harrdrive 1 also lit up but the other lights remained off. The BIOS screen for the PCIE card never showed up, but Windows detected the card and successfully installed the driver. Beyond this point, nothing worked and the tower was never recognized. The bundled web interface does not detect any of the harddrives that we have slotted in.

4 out of 5 eggsNot to bad

Pros: Good build quality at a good price. Not many other 8bay SATA3 devices out there (currently) and this seems to have the raid card (RR622) that everyone recommends. Has fairly good alerting and even email alerts for events related to the controller. Fairly quiet and it has a blue fan.. so it has that going for it.

Drive bays are easy to take in and out and have a good latching mechanism.

I have pushed about 6TB to the drive over the past day without issue.

Cons: Only con so far is that the SATA card management software could be more friendly, and its password you can apply is limited to 8 characters. In theory you can have this network accessible but they wisely give you an option when installing to not allow it to be network accessible any only viewable from localhost.(thats not a con)

The SATA card also caused problems for my bootup since my system drive is a RAID0 on the MOBO's RAID controler. However they do acknowledge this problem and give you instructions on how to resolve the issue with a BIOS update to the controller card.

Other Thoughts: My setup is 4 WD30EFRX (12TB) in the top bay in a RAID5 (9TB) ending with 8.18TB usable. This is all connected to a windows 8.1 Box currently.

The price is right and you're getting SATA3 so you don't feel like you're wasting money when you buy drives that you can't get the full potential from.
A big driver for me to get this was the ability for "Online Expansion of RAID arrays" Its a bit hard to figure out how you do this as the interface is as clear as mud. I did some playing around and if you basically recreate the raid as either a different RAID config or the same but including the new drive then it gives you the option to write back the data on the array.

Also it should be noted the card and RAID housing has 2 eSATA ports, these correspond to the top and bottom 4 bays, to use all 8 bays you need to use both eSATA cables.

How this went for me was it sat at 0% for about a 15 to 20 min eventually going from an ETA of 20 hours to around 67 hours with only 3-5gb added to a 9TB array. (though it might be doing all 9TB so it might make sense)

So i gave up on doing that and just deleted my 3 drive RAID5 array and remade it as a 4 drive RAID5, and what happened? the files were still there ?_? all i had to do was expand the partition.

Would i do this outside of a test... no, don't play around with your files unless you have a backup... so if you're going to build a 9TB array and hope to expand it down the road you should have a place to move that 9TB to incase you blow it up.

So my future plans are to use the remaining 4 bays for a second 4 drive RAID5, in theory this is the best idea since ti gives you some leverage in moving some of your files to any unused space in the other array if you need to do work on the other.

I also had to do the "fix" to disable booting from the raid controler for this setup as it conflicted with my RAID0 SSD and would not allow the system to boot with the drives powered on... even when selecting the correct boot drive from the UEFI boot screen.


Also a note i ran into an issue where when pushing files the drives basically locked up with full "activity" but nothing being written, this annihilated the array but i was able to recovery after a reboot. I traced this to a faulty mobo on the computer i was using as i have been experiencing this same issue using windows 8 storage spaces. I thought initially this was a storage spaces issue but it seems more like its a north/south bridge controller issue on the mobo

4 out of 5 eggsRunning as JBOD on MacPro

Pros: Lots of storage, quiet, cool light. Would be 5 star except read below.

Cons: could not get drive bay 1 to show up. Looked inside the unit and saw the main power button cable was in front of the back plane. Used a ruler to push it down, and now all is good.

Other Thoughts: Have 8 drives all showing up on MacPro. Using a Firmtek port multiplier card (not the original card that came with the unit) because I am on a Mac. Seems to be nice and fast!
