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.

2 out of 5 eggsSANS DIGITAL sans power supply

Pros: It did work great. Fast, reliable for a couple years -- I thought a pretty good value.

Cons: And then I nudged the power connector. And that was that.

Other Thoughts: I'm very sorry for the inconvenience Sans Digital's PSU has caused me. As an engineer, the replacement plan when the sustandard, custom designed for the space power supply inevitably craps out is to disassemble the enclosure, and unplug the drives (three old style Molex connector and a floppy drive connector). Remove the broken and useless PSU and throw it away. Get out an old ATX power supply (what good is a 20 pin mobo connector anyway nowadays?), cut the green mobo connector wire and connect it to one terminal of a switch like you'd use in a wall socket, cut the adjacent black wire and connect it to the other switch terminal. Make sure the switch is "OFF". Connect three Molex and the floppy drive connectors in their respective places, and power on the power supply with the switch you just installed. Eureka! Now the enclosure will power up, all the lights light, and you can get your data off onto another more reliable storage medium. It's a Frankenstein, but I got the data off.

Now Sans, before you offer your regret at the situation your bad design put me in, what's the going price for that *great* power supply that will likely fail just like the first one did?

FOLLOWUP: Bought 4 $3.25 12V+5V AC Adapters (FREE SHIPPING) from a large online marketplace I probably shouldn't advertise here. Instead of a $60 guaranteed to fail replacement power supply. Plugged them into their respective connectors, powered them on, and all seems to work, at least good enough to fish the data off. It is admittedly an ugly mess of wires, but it works.

4 out of 5 eggsIt's been reliable for me

Pros: Worked right off the bat in RAID 5 with 4 3TB WD Red drives.

Has a RAID configuration utility to handle setup and problems.

Has been a reliable video server for more than 2 years.

Cheap.

Note (4/2016): Sans Digital now says that it will handle 8TB drives for a max of 32TB. Have not tried that, but it seems like a plus.

Cons: Using it in eSata mode requires an eSata controller. Just adding a conversion bracket to an internal SATA won't work.

Windows still does not play nicely with external drives, and stopping its power-saving "features" from turning off drives can be a chore.

Windows 10 SMB support does not seem to extend to USB-connected drives.

These last two items are not really SansDigital's fault.

Other Thoughts: IMHO, if you don't use NAS-rated drives you are asking for trouble with RAID. Using desktop, or green, or (truly stupid) archive drives in a RAID is just begging for data loss. But I guess everyone needs to learn this the hard way.

4 out of 5 eggsSeagate 6TB and 8TB Drive Mounting Problem

Pros: They work great for use as a large drive for DVR applications. I have used four 6TB drives to make a Large 24 TB drive.

Cons: If you use the new Seagate ^TB and 8TB drives in thise or any other Sans Digital box like this beware there is no way to secure the drives in the box. These boxes use the middle hole on each side of the drive to secure the drive in the slot. The new 6TB and 8 TB Seagate drives do not have the middle hole like other drives. I guess Seagate is saving a penny per drive by omitting these two holes.

1 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.

UPDATES:

A few months ago the stock fan smoked its bearing and started making a racket. I had to buy a 2-pin to 3-pin fan adapter in order to replace it with a different model.

Then the power supply died after ~3 years of use like numerous other users are reporting. I turned it off to go on vacation and now it will not turn on again. I kept this enclosure running 24/7 and probably power cycled it less than 10 times during the time I have owned it so this issue is unacceptable. I will probably not buy another product from this company again.

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 eggsPSU quality concern

Pros: Easy to setup/use, supports up to 4TB drives, software has email alert features.

Cons: After reading all the issues folks are having with the PSU and the fact that if it goes all you data goes as well has forced me to move to using Windows Disk Management instead of the RAID controller. If this PSU dies I think I'll try mounting the back plane in an old PC case and use one of my old PC PSU's to power it. If I ever buy another tower, this unit has taught me the importance of looking at the PSU when evaluating storage towers.

Other Thoughts: Wouldn't work with windows Storage spaces, but did work with Windows Disk Management's Volume spanning. it's about a 15-20MB/s performance which really isn't a concern for media backup volumes that are only powered on for backup.

3 out of 5 eggsWorked well for 3 years

Pros: Worked well, easy to setup. Had no issues the whole 3 years I had it. It was rarely turned off that whole time.

Cons: My PSU died today. I switched it off to install some components in my PC and it wouldn't not turn back on. Hoping recovery with work without a hitch.

1 out of 5 eggsIs there an alternative power supply?

Pros: Inexpensive. Nice package. Worked well when it worked! Initially had 4 X 2TB drives in a Raid 5. Used primarily for data backup. Used both eSata and USB 3 without issues though USB worked amazingly faster on some of my servers.

Cons: No surprise.........Power Supply issues. I went through 2 power supplies in 2.5 years and gave up on it. The SD Tower Raid has been sitting in a box for 2 years since. I'm currently running short of space elsewhere and am eying e this again but I'm not going to take a chance unless..........

HAS ANYONE FOUND AND INSTALLED AN ALTERNATE POWER SUPPLY THAT WORKS IN THIS THING ?????

Looking at current reviews, it looks like the power supply issue has not been resolved by SD. I wonder if perhaps the limited amount of space available for the power is the reason? Anyway, it's an alternative PS or nothing. If you know of one, please let me/us know.

Other Thoughts: Purchased this in 2011. Gave up on it in early 2014 after the second power supply went. The only smart thing I did on the 2nd try was to set it up as Raid 1. I was able to recover all my data to another server without an issue.

5 out of 5 eggsWorks as promised.

Pros: Drives work and initialize when booted. I have it connected via the Multilane SATA and it's just fine. I now have this and the computer connected to a UPS. This is an excellent way to have extra storage to even use with BackBlaze (they don't allow NAS). I'll then synchronize this with a NAS device. It even supports the Segate Seagate Archive HDD v2 ST8000AS0002 8TB (Could support 32TB given this).

Cons: None for this model. I'll update if I do.
