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

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.

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.

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.

5 out of 5 eggsSANS DIGITAL TR4UTBPN

Pros: I have been running a pair of Western Digital Red 1TB drives in RAID 1 with this enclosure 24/7 for close to two years now with zero problems. It's not doing anything too intensive though, just media storage and file backups for a desktop machine.

The enclosure itself is very solidly built with thick metal panels and an attractive exterior finish.

Hardware RAID is great. No messing around with add-on RAID cards.

I have used both the eSATA and USB connections with no issues.

Cons: The fan is only 80mm and makes a bit of noise; I have the enclosure on my desk only ~2 feet away though so it's easy to hear.

Other Thoughts: When connected over eSATA the drives inside would get power cycled when the computer was shut down. This seems normal but I didn't like it, so I switched to USB and haven't had any problems.

2 out of 5 eggs

Pros: -Easy to Setup
-Flexible Raid Options

Cons: -Software package to administrator not very robust
-Cheap Power Supply

Other Thoughts: I had the unit for 2 years during which time I had 1 HDD failure after about a year. I replaced the failed unit and the raid array did it job to start working at full capacity again. The latest thing to go wrong was that the power supply failed after the device was powered off when I was cleaning up my home theather area. It wouldnt power back on. I had to use a spare ATX power supply to get it up and working again to recover my data.

The other reviews that stated they had trouble with the OEM power supply and the expense pushed me to replace the tower raid with a server box instead.

3 out of 5 eggsworks great until power supply dies

Pros: I got it on sale. It is small, quiet, good transfer speeds. No issues at all for over two years of daily use. Then.......

Cons: Power supply is low quality. Unit was on a APC UPS with line conditioner. It was only powered off twice. The second time it didn't come back on. Hardly any dust in unit at all. I had to rig up a PC power supply to power it so I could recover the data. I'm not happy. Probably will not buy Sans Digital products again.

5 out of 5 eggsPerfect solution for home storage

Pros: Compact, Hardware RAID (no port replicator card necessary), quiet, cost effective. Easy setup and straightforward instructions make setup a breeze.

Cons: None.

Other Thoughts: There are a lot of people claiming drives drop out on these enclosures. YOU CAN NOT USE DESKTOP HARD DRIVES WITH A RAID CONTROLLER. Desktop drives have a data recovery algorithm that takes too long to satisfy the controller. Data is not provided in the set time frame, and the controller marks the drive as offline. I HIGHLY recommend WD RED hard drives. I'm running the 1 TB WD RED drives in RAID5, not a single glitch in operation, powered up 24/7 since the day I received it.

I have an additional recommendation, besides the use of RAID/NAS/Enterprise drives: Put the enclosure in "JBOD" mode and download the drive supplier's drive scanning/health utility when you first put it together and do a complete "Exhaustive" hardware test on each individual drive. This takes a day or two per drive, but helps insure you don't have a defective drive going in. Once complete, switch to the operating mode of your choice, reset the enclosure, and enjoy!

4 out of 5 eggsNo Complaints, except for PSU

Pros: This unit is honestly the most solid enclosure I've used so far for it's price range. I've not experienced any of the catastrophic failures others have mentioned in the ~2 years I've been running this. I did swap out all the hard disks in it a few months back and it was incredibly painless to swap each out one at a time and have them automagically rebuild. The process felt like it went extremely quick (about 6 to 10 hours per disk).

Cons: I just had to purchase an open box replacement for it's PSU. After a power failure incident where it's UPS failed to protect the unit, it no longer would power up. To speed up the downtime, I just went ahead and purchased an open box item from Newegg and swapped it out. I'll be ordering a replacement power supply for the extra box here and using it as a spare or backup unit, despite knowing about the flaw.

5 out of 5 eggssimple is better

Pros: 4 bay for lower price than most 2-3. USB connection is solid and transfer speeds are comparable to every other external USB hard drive I've ever used.

Cons: RAID and eSATA are a bit finicky

Other Thoughts: I got it "to work" with my eSATA card but my speeds were all over the map. In fairness I haven't tested with any other card. I didn't buy it to use as hard drive expansion, i bought it for external backup and archival of older, less frequently used files. Plug it in using USB and it'll run about 70-110 to my dual 4TB hard drives currently in JBOD configuration. If you want more fancy features spend the money and time and see if they work. For me it does everything i need.
