I know that a number of people dislike drobo. I get it, the device is slow, when it fails it can fail hard, setup can be a pain sometimes.
Im not endorsing them either but I feel its actually not too bad of a product for at home. I can’t also help but feel thats where it fails. You only need to be at a very low skill level to use and set up the device yourself. But from reading the support forums alot of people are not at that level. When you see questions like “Whats single disk redundancy?” or “I pulled a drive out while it was recovering” I cant help but feel like the hate comes from users who fail to understand the basic concepts of raid and would look at you with blank eyes if you asked if they were using iSCSI. But that is exactally who Drobo it is marketed to.
Then on the other side you have the tech users who expect to run VMs on it or get the throughput of 8 disks over a single ethernet interface. While newer models have nic teaming and support SSDs and whatnot I still feel the devices cant compete with even the home synology devices.
All I can say is for anyone out there who was looking for the awnser to the following question: Does the Drobo Pro (2009-2010) support disks larger than 2TB, yes! Larger than 4TB, yes! And will putting in a 8TB disk fuck up my whole raid stack? No, you are fine. Drobo has been decent with patching a product that did not support disks larger than 2TB when it launched up to what I can say works to 8TB.
After suffering two disk failures over the last year I can say that my drobo is still putting along fine recovering fully both times, and has accepted every disk size up to 8TB I have thrown at it to date despite the lack of documentation on their own site regarding these large drives.
So for keeping data safe, here is a cold one to you drobo now I dont have to recover anything from backups.
