DroboPro supports drives up to 2 TB in size. DroboPro offers a choice of Firewire, USB 2.0 and Gigabit Ethernet
Other features Drobo added for businesses include dual-disk protection and thin provisioning.
Drobo has been shipping a four-bay desktop product for consumers since 2007. As with the desktop box, DroboPro lets customers mix and match disks of varying capacities from different drive makers in the same RAID group, automatically applying a combination of mirroring and striping to protect data without user intervention. Customers can remove disks and replace them with larger capacity drives, and data will be automatically rebalanced among them. Disks can also be moved from one device to another with data intact.
"It's a pretty slick implementation," said IDC analyst David Reinsel, who said he uses one of the Drobo desktop devices at home. "It automates RAID, something oftentimes people have to figure out how to do and how to fix on their own."
DroboPro can hold a maximum of 16 TB with 2 TB disk drives. Jillian Mansolf, senior vice president of sales and marketing for Data Robotics, said customers must buy another device if they want more than 16 TB. "Since we're targeting companies with 100 users or less, we feel pretty safe that they won't hit the capacity limit quickly," she said.
Customers must be cautious about hitting capacity limits when using the thin provisioning, according to Reinsel, but "that's one of the reasons even some enterprise customers today are hesitant to implement thin provisioning -- it's not just an SMB concern." DroboPro notifies customers of capacity limits with its display lights, a software dashboard and an email-alerting feature.
Drobo desktop user Wayne Titus, owner of tax accounting and wealth management firm AMDG International, said he began beta testing DroboPro about six weeks ago. Titus said he's been using two Drobo desktop devices, one at home and one for backing up files at his office. However, the USB 2.0 connection to the smaller, slower box has been overwhelmed by his attempts to do daily backups to it on 300 GB of data.
"I had the capacity to backup all my data, but not the bandwidth," he said. "I had to start being selective about what files I backed up."
Titus said he expects DroboPro will comfortably accommodate the company's performance needs with room to spare. "To test it, I had five HD video sessions running while I downloaded another HD video and did all my system backups," he said. "That's far beyond what our business would need."
Reinsel said DroboPro's ease-of-use features should be appealing to SMBs, but Data Robotics may have a hard time rising above the noise in the market for low-end storage. Just this quarter, EMC Corp. beefed up its Iomega consumer/prosumer NAS boxes; Hitachi GST acquired a company called Fabrik last month, which makes external hard drive systems for Macs and PCs; NetGear began offering a ReadyNAS line of products with pre-integrated cloud backup; and Seagate released a line of self-encrypting NAS devices called BlackArmor.
"The target customer for Drobo is tough to reach," he said. "Drobo isn't necessarily a brand they know."
