1 out of 5 eggsNot worth it at any price

Pros: cheap, but still not worth it

Cons: cheap components, less than ideal customer support if it malfunctions. Constantly had connection problems with USB 3.0

Other Thoughts: Summary:
Cheaply made and if it malfunctions you have to pay for shipping.

Why I bought it:
I own a Drobo Gen 2 and thought that if I bought this and used Windows 8 Storage Spaces with it, it would be a good replacement for the Drobo. Plus, it should be faster since it is USB 3.0 while the Drobo Gen 2 is USB 2.0.

What went wrong:
The device constantly disconnected from my computer, causing Storage Space problems. Eventually the top drive tray went out so I contacted customer support. I was willing to stick with this product and keep using it as a Drobo replacement. Unfortunately, I was informed that I would have to package it back up myself and ship it back on my own dime.

I compared this to the support I got from Drobo when my original Gen2 devce malfunctioned. They immediately sent me a new one via FedEx. The box that arrived included a return label. It was super easy and fast.

I am giving up on this product because I'm assuming that if I do ship it back, I'm just gonna get another shoddy device that won't well either and will eventually malfunction again. Why bother?

What you should get from this review:
While this device appears to be a bargain, be aware that it seems to use very cheap components and if it does malfunction, you are going to have to hassle with tech support and shipping it off, etc.

Stick with companies that treat their customers well and stand behind their products. My experience with Drobo was very positive and I think I was foolish to try and use this product as a replacement.

Sometimes you pay more, but you get so much more back.

Manufacturer Response:

Thank you for purchasing Sans Digital products.

3 out of 5 eggsDecent for storage

Pros: *Sturdy
*Quiet fan
*Green activity LEDs and orange power LED - can leave it on while sleeping, unlike other devices that have blinding blue LEDs

Cons: *Can't use Windows "Dynamic Disks"
*Doesn't report drive info properly - hangs udisks for a couple minutes on startup in Linux
*No hot-swap rails; have to take the whole case apart

Other Thoughts: If you've got one of the newer 802.11ac routers with a USB 3.0 port and OpenWRT, it'd probably turn it into a decent NAS server. It won't work with Windows software RAID, but it works fine with LVM2 in Linux, and it seems able to saturate the USB 3.0 bus if you put fast drives in it.

1 out of 5 eggsJBOD Only

Pros: Looks Nice, USB 3.0

Cons: No RAID and not worth it. Go for a Rosewill, but be prepared to work on a RAID setup with any of these external enclosures it can be a challenge. Had to return this one and pay shipping and restocking fees.

Other Thoughts: Please Someone make a better External RAID solution!

2 out of 5 eggsA little disappointed

Pros: Nice look. Space in between drives for better cooling. Fan spins slow enough so as to not be noisy. Interior construction is OK.

Cons: Main complaint is that the USB 3.0 is very unstable. Can't get through a few GB without it crashing the port requiring reboot. I've bought other cases from San Digital and the case has always been made from solid aluminum, but this one has a cheap sheet metal body.

Manufacturer Response:

Thank you for purchasing our products.

USB 3.0 unstable issues could due to incompatibility of the motherboard. There is firmware update for the USB 3.0 to eliminate the problem with disconnect and reconnect. We also recommend connect to a USB hub to check if there is any issues with the onboard USB 3.0 port. Some of the motherboard manufacture creates the USB 3.0 port out of USB 3.0 specification and hence, generating issues.

If you are having 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 e-mail supports.

4 out of 5 eggsGreat!

Pros: - Non-Expensive
- Easy to setup
- Plug & Play

Cons: - A bit on the noisy side.
- No RAID

Other Thoughts: The reason I am giving thise 4 star out of 5 star is not because of the product, but because of the reality of using software RAID with USB hard-drives

I've tried running with in software RAID, and I had to rebuild the RAID array every 2 weeks (and it tooks like 3 days, because I use 2 terabytes hard-drive)

I reverted back to a non-raid setup with my trusty rsync scripts

4 out of 5 eggsReliable Storrage

Pros: I have 6 of this model and over 30TB worth of storrage. I have two units running on ESATA 300 and 4 units running on USB dedicated adaptors. I have never had a problem accessing data on either the ESATA or USB3.0 interfaces.
I have been using this style of cabinet for about 3 years. I am very pleased with the performace and Quality.

Cons: Bad Fans. After 6 months one of the fans started to gurrrr!
I to lost # 1 SATA drive two times before I figured out that the FAN was weak, and intermittently gurring, running too slow causing the drive to heat up. I replaced fans in two cabnets, with the clear ANTEC multi speed fans for about 10 bucks each. These worked and cooled better than the stock fans because you could set a higher output speed.

Other Thoughts: Over all, I think you would be hard pressed considering the cost of these RAID enclosures to to better elsewhere. The cost of a $10 fan is nothing and plugs right in the same connector, no big deal. Operationally, they have been perfect. The RAID Rebuilds reliably also. Not hot swap.
