Raid Mode Features:

Mediasonic HUR1-SU3S2
  • Single Mode: (Non-Raid) Computer will show up as two independent drives. This function can be used if only one hard drive is installed. Or, two different brands or capacities of hard drives are installed.

  • Raid 0: (Spanning Mode) Two hard drives will show up as one large single drive. Spanning is an array (not Raid) that is written sequentially across two drives.

  • Raid 0: (Striping Mode) Two hard drives will show up as one large single drive but speed performance will boost up. The two hard drives will write data in "column" effect. This form of array splits each piece of data across both hard drives in segments. Data is stored between the first hard drive and the second hard drive. While the hard drive is striped in writing, the head of the next hard drive is moved to next track to write. The data is writing without any form of data-checking. Once one HDD is damaged, all data can be lost.

  • Raid 1: (Mirroring Mode) Using this model will require two identical hard drives and they must be the same capacity, brand, and model number. Under Raid 1, it will create an extra copy (or mirror) set of data to second drive. The backups are more important for safe keeping and the available data only shows up in one large single drive. This is useful when the first hard drive fails and it can be replaced by a second set of identical data instantly.

1 out of 5 eggsTerrible airflow, died after a month

Pros: Nice form factor, stylish, easy to setup.

Cons: Ran insanely hot with 2 HGST 4TB's in RAID 1. Stopped functioning after about a month.

5 out of 5 eggsAwesome!!!

Pros: 3.0 and eSata
Multiple RAID configurations
Small fan to keep some air flowing

Cons: None!

Other Thoughts: I picked this up for $35 because of the $40 promo code, wow!!!

I have two 1tb hard drives in RAID 0 giving me 2TB of space and they respond quickly!

I'm not a speed test guru that goes by bench marks. Just by time, moving about 250GB of data ranging from small pictures in the 1.5mb range to a few 18gb BluRay movies, this is 4-5 times faster than 2.0.

There are a couple switches on the back for the drives/fan if you want to keep the drives "on" all the time or let them go to sleep as well as the fan "on" all the time or just when it heats up. The fan is silent but tolerable if there is just regular noise going on in the house.

I have these setup on my wife's computer and shared in the home group so everyone can get to it. No lag at all.

5 out of 5 eggsJust what I needed

Pros: Now comes with a better how to CD and a printed sheet showing how to install RAID 1. So they must have seen the other reviews. It was time consuming getting the case apart so I could install my two HDD's. But the CD has good instructions. To bad it's sold out. It was a great buy.

Cons: None so far

Other Thoughts: I must have been one of the last to order this enclosure. It was on sale for half the listed price and was well worth it. Knowing what I know now I would pay the listed price. I went from a USB 2.0 JOB enclosure to this one. Being it's a USB 3.0 it a lot faster. Plus know I don't have to do a backup like I had too with the USB 2.0 JOB enclosure.

5 out of 5 eggsGreat and Useful

Pros: This is a really good quality enclosure with metal casing and plastic frame. Very easy to set up. The included CD has clear instructions for all MediaSonic enclosure products.

Cons: None.

Other Thoughts: I would purchase another MediaSonic enclose in the future, they seem to be very well built.

5 out of 5 eggsWorks with USB3 and eSATA

Pros: I tested it with two 1tb western digital blue drives and set it up as raid 1. I copied a few gigs worth of files to it, turned it off, removed 1 drive and replaced it with a blank drive the same model and size. I restarted the computer and the drive and it started rebuilding its self with no assistance from me. It took about 2 1/2 hours to rebuild

Cons: The little fan doesn't cool the drives down very much. Maybe my WD Blues run hotter than other drives.

Other Thoughts: Keep synchronization mode turned off until you get the raid setup. I have 2 computers with usb3 ports on the front of the case. This drive would not work on either one. It would just keep disconnecting and reconnecting. I had to use ports on the back of the case that are attached directly to the motherboard. I have other usb3 devices that work on my front ports but this would not.

5 out of 5 eggsThanks to Other Posters

Pros: Works with 4TB drives in RAID-1. Very Quiet and in a small box. No complaints about functioning.

Cons: I am using an E-Sata connection. Be forewarned, should you have a mobo as mine (ASUS P9X79PRO) that the unit is not hot swapable using E-Sata. Tto use you must turnthe unit on prior to booting computer for the drive to be recognized. However, the unit IS hot swapable with USB.

. .

Other Thoughts: Thanks to others who stated this enclosure DOES work with 4TB Drives! Why manufacturers don't make this clear is amazing! This ambiguity is surprisingly pervasive.

THANKS to other customers who explained setting the RAID button on inside the box (hold down button while powering).

It would be nice if manufacturers would spend a little time explaining how re-synchronisation works if one drive goes bad. I lost 2 1/2 months data on an internal RAID-1 when I did not know one drive(went offline (windows didn't say - I found out in control panel disk manager by accident), and all data written to the one drive for that duration was lost - ONLY when suddenly, inexplicably, the controller found the second drive and rebuilt the RAID - as of 2 1/2 months prior. I lost all interim data which had been written to the one drive.

MORAL OF STORY: RAID-1 works until it doesn't: ALWAYS BACK UP YOUR DATA. and make sure in Control Panel/Disk Manager that NO RAID DRIVE is ever off line! If the system chooses to rebuild the RAID later you could lose all data saved to the one drive during that interim.

5 out of 5 eggsWorks Great - Even with BitLocker!

Pros: USB 3.0 / eSata. Works with 4TB drives.

Cons: The DC power connector is not standard (not as pictured).

Other Thoughts: I purchased a couple of these enclosures and they work great in RAID 1. I tested them with both 3TB & 4TB drives (They have to be formatted in GPT above 2TB). BitLocker encryption works too. To test them, I put some test files on one and pulled the drives out. I individually hooked each drive up to a pc and they were both encrypted and had all of the files. Then, I erased one drive and put them back in the enclosure. It then automatically rebuilt the erased drive. Very impressive. A tip for setting up raid one: In addition to pressing the selection button, the enclosure must be on - hooked up to either USB, eSata, or the power sync turned off. It took me the longest time to figure out with the power sync on, it is in the power saving mode (off). I also tuned the smart fan setting off so, the fan is always on.

4 out of 5 eggsLike it so far

Pros: Effective RAID 1 external drive solution for the price
Once set up, it works as expected

Cons: Could only set the RAID mode by following the tip from the other comments: After setting dip switches, hold down button WHILE powering on the case for a moment. - The instructions (incorrectly?) say to hold down the button while power is OFF, which didn't work for me. Thanks for posting that, guys. Took a bit of extra time to sort that out.

Other Thoughts: Why were 2 Screws included?

4 out of 5 eggsNice Little Raid

Pros: I was easily able to set up the drive in RAID 1 configuration. The only tricky part was holding the button down inside the drive to set the raid configuration. Key: Hold the button down, press the power button and then let go of the button inside the drive. Otherwise, everything flowed exactly as I expected. It hooked up easily to my Mac Mini and Windows 7 laptop without an issue.

Cons: Newegg web site does not accurately identify the capacity of drives this can handle. I was in a little bit of a panic when the box says it can handle 2 x 2 TB drives. I was pleasantly surprised to find it holds 2 x 4 TB drives according to the documentation and manufacturers web site. That is the reason I marked it down 1 egg.

5 out of 5 eggsWorks amazing

Pros: Dropped my load temps by 25 degrees! My previous load temps where around 55 with the stock AMD cooler, this has brought it to about 30! It is also much quieter.

Cons: None so far

Other Thoughts: AMD Phenom ii x6 1055T (will overclock and rerevew)
