3 out of 5 eggsGood product if you know what you're doing, but still a mixed bag

Pros: Price seems right for this product. The enclosure build quality is just fine. Overall not bad. The fan is replaceable. Firmware does support 2TB drives.

Cons: The fan in this enclosure is much too loud. I can hear it over all three on my PCs in my office including my server. Maybe the other reviewers don't take noise control as seriously as I do.

The model number of the included fan is DF128025SL which is rated at 29CFM and 24dBA. But in that enclosure it makes a whooshing sound.

I suggest replacing the fan with this model: ENERMAX Marathon Enlobal 80mm (24CFM, 14dBA). It’s an easy replacement to do. You will need to find a 3 pin to 2 pin converter, or just clip the leads and replace.

Also, don't even try to run this enclosure with anything but a SIL3132 chipset. It just won't work. I tried everything from AMD SATA host controllers to Intel to Highpoint. None will work. Save yourself time and effort and buy the “SYBA SD-SA2PEX-1E1I PCI Express SATA II Controller Card” here on NewEgg when you buy this enclosure.

Other Thoughts: I did check the firmware on the enclosure as described in another post below. It's newer than anything on the SiliconImage website.

3 out of 5 eggsGood idea but build quality may be an issue

Pros: Great way to create affordable RAID with mirroring. Mirroring takes away the fear of losing data when a drive dies because you theoretically still have a viable drive with the data. This is an affordable solution that allows you to create your own transportable and secure backup. The only potential glitch, I suppose, is getting a drive contaminated with some virus or something....

Cons: First one was flawless. Second one was DOA. Also, the instructions in the manual are a bit sparse. I'm awaiting for the second one to be exchanged. Hopefully, I'll be 2 for 3. If my second box had been functional, my rating would be 5 out of 5.

Other Thoughts: I called the Sans Digital tech support number after hours and was surprised to get a helpful and friendly voice after no wait. He confirmed my second enclosure was, indeed, DOA and advised a NewEgg return.

2 out of 5 eggsDOA power supply

Pros: Small and quiet. If you just need a small two drive unit this is not a bad choice.

Cons: The power supply brick was DOA out of the box. To their credit Sans digital answered on the first ring and supplied an RMA #.

Other Thoughts: If you buy this unit make sure that you also purchase a Sil3132 esata card or you will only see one drive. Note you can make one big volume out of the two drives on a standard esata connector. This box does not support hot swapping of sata drives like the AMS 2-Bay sata raid does.

Manufacturer Response:

Please contact or call 1.800.980.1988 if you have problem with the unit. The controller card are need only on JBOD mode. Since you are using a single cable to see 2 drives, port multiplier is required in order for this application.

4 out of 5 eggs

Pros: Small, quiet, properly ventilated, initialized and created a RAID1 array without losing any data on original drive.

Cons: Only 4 screws included for the hdd's, useless eSATA Jmicron controller that is built into my motherboard can't detect it properly (shows as 8589MB disk no matter what I tried to do).

Other Thoughts: Uses a regular Sil5744 controller so you can download a SteelVine Manager utility (from SiliconImage's website) to view and manage various properties for this enclosure and update teh BIOS (if you have an outdated version).

4 out of 5 eggsIt Works

Pros: Good ventilation and fairly quiet. No wall wart PSU.

Cons: Only 4 thumbscrews provided. Four more would have been appreciated.

Other Thoughts: Used in RAID 1 configuration with a pair of Western Digital 1TB 16MB 'green' drives for iTunes (for Windows) library - drawing 22 watts per Kill-A-Watt

5 out of 5 eggsA bit bulky but does what it supposed to do

Pros: Foremost, after testing I've verified it performs the RAID 1 function correctly with 1TB Samsung F1 drives (unlike the Kingwin model). Two, it runs very cool as it has a nice size quiet fan and good venting at each end. Thirdly, each drives is easily accessible for pulling and replacing if needed. And lastly the supplied power supply is nicer than most (again I refer to the cheaper Kingwin model) as it runs very cool and supplies 12V at 5 amps, more than enough to drive the unit. Its also grounded which is a safety plus.

Cons: It supposed to be tool-less by using thumb screws but Sans Digital only ships four thumb screws for mounting the two drives. The manual implies they ship eight but they only give you four - as shown in Newegg's parts photo.) You could get by with only two screws per drive but I'm old school by believing in using four screws per drive for solid mounting. My drives came with their own screws so I'm OK but the unit now no longer tool-less. (In Sans Digital's follow-up model they ditched the thumb screws approach altogether.)

Other Thoughts: Changing the unit's RAID mode is easy and unambiguous.

5 out of 5 eggsDown and Dirty Simple

Pros: Tool-less installation and set up (if you don't count the paperclip you need to press the reset button.)
A great little box that does exactly what it says. Toss in two drives, set the dip switches for the drive configuration you want and press the reset button. It just works.
It does come with a 1m eSATA cable which is not listed or shown in the photo on this site but it is listed in the supplied parts list on Sans Digital site.
It is nice knowing I have a Raid1 setup that can be recovered by any system in the event the box dies. Short of buying a bigger power supply and stuffing my PC case with drives this is one of the most cost effective solutions for cheap space/security.

Cons: External power supply

Other Thoughts: All that extra space inside the box and they still give you a power brick?
