data roboの略なんだけど、ドロボーに読めてしまうな...
けど、動画デモ見ると、かなり便利そう。
ホットスワップしているし、でも、同期時間みたいのはどうしているのかな。
USB接続だ。ただ、ドライブ抜きで$700だって。まだまだ高い。

Robotic Operations
    Drobo is programmed to take actions on your behalf; always ensuring it's keeping your data safe and optimized:

        * Auto-formatting of added drives1
        * Auto-repair of data after drive failure
        * Auto-repair of data corruption
        * Auto-repair of data redundancy
        * Auto-expansion of storage pool
        * (when drives are added or upsized)
        * Auto-sense & display of capacity used

Consolidated Capacity
    Regardless of how many hard drives are installed, your Mac or PC sees one large drive:

        * Consolidation of storage into large pool
        * Accessible via High-Speed USB 2.0
        * Accepts one to four drives.

Automated Protection
    Data on Drobo is automatically protected against drive failure and data corruption:

        * Redundant protection of all data
        * Protection against drive failure
        * Sensing and avoiding data corruption
        * Auto-repair of data after drive failure2
        * Protection against multiple drive failures2

Flexible Configuration
    It's extremely easy to add capacity to Drobo; just like adding ink to a printer:

        * Uses standard 3.5" SATA I or II drives
        * Accepts any brand, capacity, or speed
        * No tools, just insert drives into slots

Infinite Expansion
    Expand capacity forever by adding new, or upsizing installed drives without data migration or configuration:

        * Insert new drives to any available bay
        * Replace installed hard drives with larger drives to increase total capacity
        * New capacity is available instantly
        * Add drives without downtime or configuration

Intuitive Indicators
    Drobo informs you what actions are required with simple to understand indicator lights (no software required)

        * Green = healthy, no action necessary
        * Yellow = low, add drive here soon
        * Red = full, add drive immediately
        * Flashing red = failure, replace drive
