Drobo S - expensive but good.,
This review is from: Drobo S DRDR4A31 5-Bay eSATA/FireWire 800/USB 3.0 DAS (Accessory)I recently bought one of these after looking at various storage options. I'm very pleased with my purchase. It's the most easy to set up and use storage solution avalable and dual disk redundancy is built in-if a disk fails just hot-plug a new one (any brand) and Drobo does the rest. Mine has 8.5TB of storage configurd for just over 3TB with dual redundancy.
Two words of warning:
Firstly USB 3, although faster than USB 2 is nowhere near the claimed speed with current drivers/hardware, perhaps twice as fast as USB 2 but well shy of e-sata speeds. For best performance you may need a pci-e e-sata card (specific cards are recommended by drobo and cost £15-35). From my experience onboard e-sata implementations are a bit unpredictable. E-sata is fast but speed will depend upon the combination of disks you use and I'm sure the drobo's controller produces a speed hit too - it won't reach theoretical maximum sata 2 speeds.
Secondly it is NOT a complete backup solution, disk failure is covered but if the drobo itself fails you need a new drobo (drobo storage has a proprietary format which only another drobo will read) and in a worst case scenario if the drobo failure corrupts your data even this might not save you (v unlikley but possible). You really need at least one other data copy, for example a disk image via an external dock (ideally kept off site) and then you really are covered.
It's expensive but that's the price of peace of mind. I haven't regretted the purchase for a moment.
