Sans Digital TowerRAID TR4UTBPN - Four-Bay USB 3.0 / eSATA Hardware RAID 5 Tower

Features

Sans Digital

The TowerRAID TR4UTBPN is a four-bay hardware RAID 5 storage tower that utilizes high performance USB 3.0 and eSATA interfaces to provide over 200MBps in performance. The included USB 3.0 port is backwards compatible with widely available USB 2.0 ports, which is a convenient feature when both USB 3.0 and eSATA connections are unavailable.

With built-in RAID 0, 1, 10, 3, 5 with hot-spare and JBOD, the TR4UTBPN provides hardware RAID redundancy protection against hard drive failures. A brand new RAID mode, CLONE or N-Way Mirror, is also introduced to replicate the saved data throughout each installed hard drive. The RAID engine is embedded within the enclosure and performs all RAID parity calculation to reduce CPU utilization from the host PC. RAID controller cards are unnecessary. The TR4UTBPN is the ultimate RAID storage for all storage needs.



Sans Digital

1 out of 5 eggsIt has $3 power supply as a base

Pros: Works fine when it works.

Cons: I have 4 devices with 16 HDDs installed. Two towers are dead - power supplies out of order. All hard drives in good in health.
RAID5 should protect my data, but it ruins it.

Other Thoughts: Reliability of modern hard drives is much higher than some devices above them.

5 out of 5 eggsWorking great out of the box

Pros: Fast. Easy to set up. Cheap. Looks nice. Quiet.

Cons: Outdated software, downloads from Sans Digital's website wouldn't work. Had to use the CD.

Other Thoughts: Out of the box I used 4 2TB Seagate Barracuda drives in raid 5. I'm getting 200+MB/s read and write sequential transfers from both my sony laptop and my surface pro 3 over USB 3.0. It is not loud at all and initial setup was very easy as it uses thumb screws for the case and all the drives.

The raid monitoring software works well for how simple it is even on windows 8.1, but I could not download it from their website as the pages would time out. I used another computer to grab the files off the included CD instead as none of my computers have CD drives. The "Turbo USB 3.0" driver does not work with windows 8.1, but as I mentioned earlier transfer speeds are over 200MB/s read and write without it plug and play.

I'll see how the longevity of the device is, but out of the box I have no problems.

1 out of 5 eggsSANS DIGITAL TR4UTBPN

Pros: SANS DIGITAL Tech support only took one week to get back to me! :-(

Cons: SANS DIGITAL TR4UTBPN was purchased to replace a failed unit. The new one failed within 3 months. NewEgg won't warranty.

Other Thoughts: To have two new units fail within 1 year and 3 months respectively is unacceptable. Next time I will spend more money with a better company who takes care of both their products and customers. This goes for NewEgg for their skimpy 30 day return policy and SANS DIGITAL for making shoddy goods they won't warranty.

1 out of 5 eggsFAIL #2 by SANS DIGITAL TR4UTBPN

Pros: Works fine when it works.

Cons: I bought this unit to replace the one I had that failed within a year because I was told from SANS DIGITAL tech support it would cost half the price of the unit to fix it. So, I bought a new one which failed in three months.

Other Thoughts: Pretty cheap stuff to have two of them fail within a year. Next time I will spend a little more money with a company that takes better care of its products and customers.

4 out of 5 eggsPretty good raid enclosure

Pros: Works well with 2tb WD Red drives.
I have TWO of these suckers connected via USB3 to a linux box. All 8 WD Red 2tb is set up as a single software RAID6.

Its been working well for the last year.

Cons: Its not unusual to wait 10-30 seconds for the software raid6 to "spin up" when accessing a new directory, for example.
Once it has started to spin though, it definitely is fast enough to stream 1080P video to a PS3.

To be fair, its unknown whether this is a fault of the enclosure or a problem with the linux box or a problem with software raid6 in general

5 out of 5 eggsGold Standard

Pros: These are really the best there is as far as functionality.
Very good software for a hardware raid, watch out for the spindown timers, I change the service startup to manual.

Cons: Power Supply quality isn't great, probably will not last more that 2 years
The 80mm fan isn't very quiet at 1800 RPM, I've replaced them with a Silenx thermistor controlled.

Other Thoughts: I have a few of these cabinets, this is my first of this model. I bought this item "Open Box" from NewEgg, glad I took the chance, all was well with it.

2 out of 5 eggsAt least the PSU hasn't died yet

Pros: Quiet. Raid works.

Cons: Slow. Maybe mine isn't working correctly.

Other Thoughts: Had this connected to an eSATA pcie adapter. Speed wasn't great. 50Mb/s. Replaced card with USB 3.0. Now getting a lousy 6 Mb/s. Tried to use switch to the internal eSATA port on my machine. When trying to access the device from that connection, the data is corrupt. Not sure how to make this thing faster.

Manufacturer Response:

Thank you for purchasing our Sans Digital product.

I apologize for this issue, as these are not the transfer speeds you should be getting from this enclosure. Because you have tested across three different connections, a lot of factors could have contributed to each issue you are having, such as an incorrect or outdated driver, outdated firmware version for the on-board usb 3.0 connection or an issue with your HDDs.

Please contact our Technical Engineers at 1-800-980-1988 or tech@sansdigital.com to allow us to gather more information and troubleshoot your issue.

2 out of 5 eggsPower supply died

Pros: Easy to use, easy to setup, lot of RAID options, no significant noise.

Cons: Power supply goes out easily when trying to move the unit

Other Thoughts: I have had two of these for the past 3 years. I have installed them at two different locations, one at home other at my office. They worked fine till they did.

One day last month I had to slightly shift the RAID enclosure, at home, as I had purchased a new desk. As I picked it up to turn the powerswitch in the back off It quit working. Power supply died.

Same exact thing happened in my office 2 weeks later.

I am not sure if the power-supply is sensitive to motion. In that case why we do-not have a power switch in the front.

Manufacturer Response:

Thank you for purchasing our Sans Digital product.

I am sorry to hear about the failed power supplies, this could have been caused by prolonged overheating. It is recommended to routinely clean out the PSU and enclosure with compressed air and to store the enclosure in a place with good air circulation.

To discuss your case further, please call 1-800-980-1988 to get in touch with one of our Technical Engineers, or email us at tech@sansdigital.com.

2 out of 5 eggsPower supply died.

Pros: It worked good until the power supply died.

Cons: The power supply died after 18 months.

Other Thoughts: Replacement PSU is about $60. Output power connectors are 3 molex and 1 floppy so perhaps a spare computer PSU could be mounted externally.

Manufacturer Response:

Thank you for purchasing our Sans Digital product.

I apologize for the inconvenience this issue has caused, the power supply should not have died this soon.

To discuss your case further, please call 1-800-980-1988 to get in touch with one of our Technical Engineers, or email us at tech@sansdigital.com.

5 out of 5 eggsWould by again

Pros: Relatively quiet - I would not keep it on my desk though.

Worked smoothly with two 3GB seagate HDs (Seagate Barracuda 7200.14 ST3000DM001) - Those get poor reviews but they have done well for me in this RAID backup.

Both USB 3.0 and eSata connection. I had slightly better results with USB 3.0 but I think that is a limit of my mainboard (eSata 3Gb/s)

This worked connected to my router via USB, ASUS RT-N56U @ 12MB/S, and also to Netgear NIght hawk @ 20-25MB/s over a wired 1Gb/s connection. Although with the netgear router I would have issues of folders and files not being able to be read. When connected directly to PC this never happened.

It has worked out well for me, esp for the price. I would buy it again. There are certainly better ones out there but I couldn't find any that were cheaper at the time.

Cons: The case fan initially blew outward, I swapped it around to blow inward for a positive pressure system.

I have yet to have problems with the power supply that other reviewers note.

AFter reading all the problems with the Power supply, I am going to stick with only these two disks as to not put too much stress on the PS.

Other Thoughts: via esata cable and two 3GB seagate HD in RAID 1 :

HD Tune: H/W RAID1 Benchmark

Transfer Rate Minimum : 127.3 MB/sec
Transfer Rate Maximum : 150.3 MB/sec
Transfer Rate Average : 137.8 MB/sec
Access Time : 11.4 ms
Burst Rate : 113.3 MB/sec
CPU Usage : -1.0%

I purchased this item on sale in Dec 2012. I am surprised it has not come down in price.

Supplied USB 3 cable is 4 ft long.
