2Bay Firewire | USB 3.0 DAS Button Tray RAID | Enclosure - Black

Are you thinking about installing an ultrafast RAID array, but you either have a laptop, don't want to open up your PC, and/or don't want to mess with drivers and complicated configurations? Monoprice has the answer to your needs in the form of this 2-bay 3.5" HDD USB 3.0/eSATA/Firewire 800 RAID Enclosure!

This RAID enclosure is perfect for increasing data throughput speed using the RAID 0 striping mode or for increasing data security using the RAID 1 mirror mode. It supports two 3.5" SATA III (6.0 Gbps) drives up to 3TB each and has even been tested with the latest Hitachi 4TB drives for up to 8TB of storage using the RAID 0 mode.

This aluminum enclosure is completely self-contained, with everything needed to connect to a Windows, Mac, or Linux computer using a USB cable (included), except the drives themselves, of course. It has a built-in 70 watt power supply, which provides 12 VDC and 5 VDC power levels from any 100 ~ 240 VAC power source, and a 60mm fan to keep things cool. In addition to the USB 3.0 interface, it includes an eSATA II (3.0 Gbps) and two Firewire 800 ports.

It features an energy (and drive) saving standby mode, which is automatically activated when the connected PC is put into "sleep" or "standby" mode. Drive installation is made easier with the ability to hot swap drives in and out of the system without turning off either the enclosure or the connected PC. Most importantly, it contains all the controllers, drivers, and software needed to operate and maintain the RAID array, making RAID installation and configuration as simple and easy as it can possibly be.

Great.. Has good factory support

Pros: USB3 and ESata. Internal power supply. Completely quiet.

Cons: Originally, I set it up with 2 x 700GB drives. One of the drives was bad. No real indications on the device if there is a problem when you install drives. If you use a bad drive in the top, it won't initialize in windows. Use one in the bottom, and the RAID sync time will never complete.

I bought one of these indirectly through a sub-vendor. It's complete with the monoprice name.
Default out of the box at RAID 1. I've got 2 x 3TB drives in it. It's a branded RAIDON ?GR3630-WSB3.
While messing with my bad drive, I ventured to send support (RAIDON) an email. They replied within 12 hours, had impeccable english and were very ready to help.

Not the best choice for a Mac user

Pros: Solidly made, lots of connection options

Cons: It seems to have a mind of its own with respect to spontaneously unmounting

This unit would be great if it wouldn't unmount on its own. I have set the computer not to let drives sleep but this unit seems to ignore that. I am not a happy camper.

Hi Franklin,

Thank you for your review on PID 10203. Just to verify, which Mac OSX version is that computer currently running? Is it a laptop or a desktop? Is the computer doing anything in particular when this happens or does any sort of error pop up? What are the makes and models of the drives in use? Also, do you happen to have the order number for this enclosure? Please let me know so we can best look into this issue. My apologies for the trouble and thank you in advance.

I have already returned the unit for a store credit and may or may not order the USB3 only unit which seems to have the same firmware sleep issue or go with another brand of unit and use the store credit for other products.

by Franklin Marder
I am running 10.11.1 but the problems existed under 10.10.5 as well. Since it happens spontaneously it's hard to pinpoint specific activity. The drives are 4 TB HGST NAS drives which replaced 2 TB Toshiba drives.

I'm sorry for the delayed response. I have submitted a complaint on the enclosure so we can keep an eye out for this problem. I have yet to see this happen with any Windows setups, but I did notice one other case of this happening on another Mac. We truly value your time and feedback as this helps us properly investigate issues and find solutions as needed. If there is anything else that I can assist you with at this time, please feel free to let me know!

Great Unit - Sleep is an issue

  • Mark S,

Pros: Great Unit. Looks nice, functions properly. Easy to set up. Very Quiet!!

Cons: Energy Saver Mode cannot be disabled.

This is really a super little 2 bay raid unit. I was very sad to see it go!!

I bought it because of the eSATA connection. I have FW800, USB2 & eSATA (via an OWC Eccelsior PCIe card) on my 2010 MacPro.The eSATA is twice as fast as FW800, which in turn is twice as fast as USB2. Unfortunately, when the unit goes into "Sleep" mode (or Energy Saver mode) when connected by the eSATA cable, the unit ejects itself from the MacPro and the unit cannot be woken up. There is the potential for data loss, and the MacPro locks up and has to be shutdown. If the sleep mode could be disabled, the unit would be a keeper.

If you are not using the eSATA connection, this is a great little RAID and works nicely under FW or USB.

Pros: Inexpensive, LCD screen is informative.

Cons: I would have liked less plastic hardware and would pay more for a metal brackets, how much more would that have cost anyway. The lights are not dimmable.

So far so good, all in all satisfied.

So far so good!

Pros: Compact size, well made, quiet fan, multiple connection sources. Easy installation.

Cons: LCD and LED's a little brighter than what I'd like for a theater room. Very sensitive tray latch buttons.

First I'd like to say I was somewhat concerned about this unit since the description said it supports up to 3TB drives. Regardless, I ended up installing 2 brand new WD Red 4TB drives (Model: WD40EFRX).

The installation in the trays was very straight forward and slide back in with ease. The latch button is a little touchy so you have to be careful with that. I must have inadvertently touch it while I was carrying it downstairs and one of the trays slid out almost sending the new drive to the floor.

I powered the unit up and it did a quick verification of both drives with a status of OK. That made me feel a little better. A couple clicks on the front panel button confirmed I was running a RAID 1 array. That made me feel a lot better. But I still needed to see if my machine could recognize the array and I still had to partition and format. That was going to be the real test. I am using the Firewire connections by the way.

Sure enough. My Ubuntu 14.4 installation saw the array as a 4TB drive no problem. I went ahead and formatted as ext3 file system without a hitch as well. Now I was happy.

Unit seems very solid and well made. I has only been operational for a few hours and I am copying over 3TB to this new array. I'll take over 12 hours to complete. I can monitor the internal temperature and fan speed as well via the LCD display to that is kind of cool.

Speaking of the LCD display, it is VERY and I do mean VERY bright. This unit is in a lighting controlled home theater behind thick smoked glass doors and still manages to cast a blue hue on half the room. I may attempt to put a dark piece of plastic over it see if I can dim it a bit.

Other than that, I am very happy with what I've seen so far. If after a few months I see no issues, I will come back and pickup another one since I have about 12TB more to move over.
