Pros: Form factor, straight-forward design, lack of power brick, LED for status. ESata connection to my computer creates an extremely fast and portable RAID 1. Good price/performance. I like this (older) design to the newer design with the slanted top panel. I found the stupid mini screw hole on the new "+" unit to blow chunks. So I bought a second one of this older model.

Cons: Problematic USB connection. Let's face it, this device to doing too much work for the loose nature of the USB physical connection. Or the internal USB hardware/software sucks? I don't know, as I do not use the USB connection after having a couple of spurious "rebuilds" using it on my laptop. My new laptop has an eSata port on the replicator - problem solved.

Overall Review: Suggest limiting this to eSata use only unless you have some means to really secure the USB cable. Using eSata, the device is extremely reliable. Using USB (like with a laptop) I got spurious rebuilds, etc. Fan noise is nominal - I prefer fan noise to toasted drives and running Sata drives without cooling fans is just stupid. I really like the square enclosure, so handy in a confined office space to have usable flat storage for small stuff.

Pros: On paper, the price/performance appears to be high. Cisco is an established company, and in time this product will potentially be a good one. Or not.

Cons: Would not connect to my ISP using the default DHCP settings, and their (highly recommended by them in the set up manual) wizard. The Juniper unit I was (at that time) contemplating replacing, has been connected to my DSL line for years. The new Cisco would NOT connect. Then, the bad part. How to reach Cisco for assistance? First I had to establish a login account with their "small biz (their spelling, not mine)" group. Fine, except the stupid drowning-in-Java web page was down. So I forwarded my issue to the web link provided. And was unable to do ANYTHING until they replied with an email link to formalize my account. Waste of 8 hours. So I login into my "small biz" support/forum area. I post a detailed note and asked if anyone had experienced this issue? I let it sit for 24 hours. Not a single reply...OK, it's a new unit. I then logged into the "chat" session and no one responded in the 45 minutes I sat there.

Overall Review: I RMA'd the unit. I bought a new Juniper. It connected out of the box. I felt like a very small voice yelling into a giant wilderness when I unsuccessfully attempted to get support with Cisco. They DID reply in the forum, 1.5 days late. All manner of apologies, etc. I'm sorry, I cannot wait for you to get sorted.
