Sorry....
Looking for a enclosure that will let me connect it to my computer either via firewire, network, eSata. Must be able to support 4 drives that are not all the same. IE 2 500gig and 2 300 gig. Hope this makes sense. Just a box that I connect to my system for storage. Not going to be running programs or rendering off of it. Just want it to put files on. Sonnet looks a little out of my price range.
Drobo, I had it for three days, worked on it for the whole three days, spent 4-5 hours on the line with there tech support. The big issue I had was this. With the drobo, if your system goes to sleep the drobo goes into standby mode, not a problem. The problem happens when you wake the computer up, the drobo will not wake up. You will get a flashing green light at the bottom of the drobo. Once you get that you have to shut down the drobo, shut down your computer and restart them both. Only, the drobo will not restart. You will get the flashing green light again. What you then have to do is pull out your disks and rebuild the drives. Which in my case I lost data once, the other times it rebuilt itself with any issues, thank god this was only test data, but lost the data non the less.
If you are like me and leave your computer on and put it into sleep mode this will kill the drobo. Tech support basically said, if you are going to be puttying your computer into sleep mode then you need to put your drobo into standby mode, turn off your computer, then turn off your drobo then restart your computer to put it into sleep mode?!?!?! WTF. What is funny, I did this on the phone with tech support. I then started up the drobo just to make sure it would start up and it didn't. I had to rebuild all the drives. The lady on the phone didn't know what to do. I then called back again, they were closing by this time and had the exact same thing happen on the phone with a different tech. This doesn't seem to be as big an issue when using windows, but on the Mac side you will see lots of posts about this. I sent mine back after three days of dealing with this. I wasn't going to trust my data to something that might start back up.
If you visit the drobo forums you will find many similier posts and concerns. The product it self, when it is running is great. I just did not want to have to hassle or worry about my data if my computer goes into sleep mode.
