The MobileSTOR MS4UT+B is a 4-bay hardware RAID 5 storage tower that utilizes high performance USB 3.0 and eSATA interfaces to provide over 200MB/s 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 and spanning, the MS4UT+B provides hardware RAID redundancy protection against hard drive failures. 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. Four hot-swappable hard drives slots are behind the front cover to allow for easy trouble shooting and hard drive replacement. The newly trayless design allows for easy installation. With adjustable cooling fan design, and high performance transfer rate to support various audio and video formats, MS4UT+B is the ideal storage tower for high-end computing.

  • newegg eSATA and USB 3.0 Host Interfaces Featuring eSATA and USB 3.0 interfaces, the 4-bay SANS DIGITAL MS4UT+B allows you to access four SATA hard drives with up to 200MB/s transfer speed.

Terrible 8/8/2015 12:30:52 PM

Pros: Good when it works.

Cons: Keeps going into power conserve when it shouldn't, Emailed tech support they really were not much help.
I used 4 Enterprise class WD 2tb's in raid 5.

Overall Review: After 2 months of use the drive cycled connection to computer any big file transfers above 3gb it would disconnect. Needless to say I lost 1.5TB of information cause I cant transfer it off the raid. Complete garbage cra.p product.

Do yourself a favor and stay away from these standlone raid boxes. Your better off getting two 2 bay sata docks and running each set in raid 1 via windows software raid. Its not possible losing data this way cause both drives can work separate if enclosure fails or a drive fails. And your not dependent on enclosure rebuilding the array or in my case enclosure failing. Keep it connected to APC battery backup for surge suppression and power conditioning.

These are my personal opinions for better data security but always have master backup drive thats not connected to a computer and in static bag. Lucky I had a backup of the raid that was about 2 months old still lost total of about 500-600gb.

NICE! 2/20/2015 5:06:59 PM

Pros: Raid built into unit, does not require a card to be installed in pc, so this unit can be plugged into a single esata port on a laptop, or onto a router that supports usb 3.0 and raid functions on both the 2 ports even on the usb port!

Cons: Documentation Sucks! Does not explain much about the unit, but how much can you say on 1 sheet of paper....... just baskics

Overall Review: Unit is better than I expected!!! I can use either the built in usb 3.0 port to access or the single esata port! Also, they do not explain that the unit auto shuts off if you do not have an active connection using the usb or esata. It was very simple to setup.... Install your drives, set your raid level, (this was covered on instructions) and then unit shuts down. IF using raid level 0,1,3,5,or 10 it may take some time for unit to build the raid drive, but IT DOES NOT FORMAT!!!!! You need after it builds the raid, connect to computer, and use disc partition finish setting up the drives! Thats it.

I thought it wasn't going to work but... 8/8/2014 5:52:13 PM

Pros: Took an existing 3T RAID+5 array I have used for over 5 years in an older Sans Digital model, positioned the drives per the documentation and tried to operate it standalone and got the same problem reported where it appeared to shutoff. The older unit booted up and stayed on and I expected the same.

Stepped back a bit ,rechecked everything and got a hunch to operate it while connected to the system and
Lo and Behold it worked as I would have expected.

Best thing thing was my original array was interpreted correctly and the transition (knock on wood) was seamless. A weekend burn in will confirm the unit's operational status but at this writing it is holding up well.

Cons: The documentation should be more emphatic about the power-on-if connected-conserve-power-if-not concept. It is not really underscored much which is a bit odd since I personally like that feature. Now I can have the unit hibernate at system shutdown which was not the case in the older unit, that required turning off separately..

Overall Review: I have not looked for any raid management utility software for the new unit and if I can't find any that would be a disappointment but since my old unit's power supply was failing I can't really complain.

Update of previous review 12/31/2013 6:55:47 PM

Pros: Appears to function after tech support session. Once they saw my previous review on NewEgg, Sans Digital was eager to help me get the device working. Worked under USB 3.0. Device does not appear if connected to USB 2.0 (which is probably appropriate given the size of the device.)

Cons: Documentation is mediocre at best. While the device appears to work under Linux, the support software is Windows only. Not all setup functions can be performed from the support software. The setup procedure is byzantine. It was not clear how to get a response from tech support (but once I got in touch with them, they were helpful). I was unable to get the esata interface to work, but I have no way to tell whether the esata hardware on the computer side is working.

Overall Review: This particular device is not currently stocked by NewEgg. Perhaps the newer offerings are easier to set up.

Doesn't work 11/13/2013 7:18:55 PM

Pros: None as far as I can tell.

Cons: Poorly documented and expensive, but at least it doesn't work.

Overall Review: Unit powers up... then turns off; power light orange. No explanation, no documentation that would give a clue as to what's going on. The only way to try again is to unplug it; none of the buttons have any effect. Doesn't matter how many or what sort of drives are in it. Haven't been able to make it work in any way, shape, or form. Should have bought beer with the money instead.

Manufacturer Response:
Thank you for purchasing Sans Digital products.

Have you connected the unit to your computer with either USB or eSATA cable? The unit has an auto off feature that it will turn itself off when it detects no connectivities to the computer in order to save energy and life of drives. This is also mentioned in the quick start guide of the unit as well. However, if you have already done so but the problem is still exist, then I suggest you to contact our tech support for help.

If you have problem on the unit, please contact us by calling 1-800-980-1988 for technical support and our engineer will try to resolve it over the phone. You can also contact us at tech@sansdigital.com for email support.
