Question: I plan on storing all of my Photos (>200k) on the Drobo and accessing the photos from there to process them using Photoshop.  Is it fast enough?
Document: So far I haven't had any issues with my Drobo USB 3.0 4-Bay Storage Array. Quiet and fast. Using the Blackmagic Disk Speed Test, read/write times varied, but they were within the ranges of what you'd expect out of a USB 3 drive (Read: 120MBps Write: 80MBps (it can go higher)). I have 4x 4TB WD Green drives (not 7200rpm) in it, for close to 11TB of redundant storage.
I just got my drobo today. Shipping was fast, nicely packaged and the unit was in a free drobo bag in the box. It is a very small unit, and runs extremely quiet. There were no instructions or manuals in the box, but you don't really need anything. All you have to do is go to[...] download the drobo dashboard client for your OS and get any instructions that you need.
For reference, these tests were run on four identical 3TB Western Digital Green drives with a combined usable capacity inside the Drobo of 8GB, of which I was using almost 6.5GB (so they were pretty full, which partially explains the super slow speeds on my old Drobo, though the speeds weren't much better when the drives were mostly empty).
I wanted to get a quick review out for the people that are looking to buy this recently released product.Opened and configured this Drobo and i'm seeing WRITE speeds between 65-107 MB/s (using 4x2TB WD Green hdds) while transferring my large media files. The noise is tolerable, mostly coming from the spinning hard drives. They sound like a rumbling stomach after a nice night of curry buffet.
Received my Drobo yesterday evening before I get started I had purchased a 5N from Amazon a few months ago an returned it. Seen where this newer model came out thought I would give Drobo another try and I'm glad I did. This machine is quite and fast after doing the setup I started during my backup from my Mac (155GB) it a short time doing it, tomorrow I'll be creating my Time Machine backup looking forward to many years with my new Drobo.Will keep you updated as I go along.
I could hand this off to my grandma with full confidence. I don't believe Drobo's target market is for the super h4ck3r nerd. This product was made for people with a busy lifestyle who want a headache free simple setup, and ease of use when storing their data.
Drobo's are notoriously noisy and slow. With this one they've fixed some of the sluggishness but it's still very noisy. Because of that I wouldn't recommend using it on your desk. The noise is not from my disks (which are 4 x WD Green 2TB - a bit chirpy but generally pretty good) because it's the same when I pull all the disks out. The sound from the fan seems to resonate around the metal enclosure and the cheap plastic fan grill on the back vibrates.
It took them long enough, but it seems that Drobo have finally gotten it right this time with their original namesake device!IMPORTANT NOTE FOR PEOPLE MIGRATING TO THIS NEW 3RD-GENERATION DROBO FROM EITHER 1ST-GENERATION OR 2ND-GENERATION DROBOS: If like me you are interested in buying one of these new Drobos for performance improvements over your current Drobo and want to migrate your hard drives, based on the migration charts on Drobo's website this is a one-way road... i.e.
I migrated these hard drives from the old Drobo to the new one, and ran identical tests before and after the migration.
I own two 2nd-generation Drobo 4-bay devices, and I've definitely had a love-hate relationship with them. Both Drobos had to be replaced at one point because of issues with the Firewire connections.
Answer: Since USB 3.0 is faster than SCSI, I doubt that you'll have a problem. However, I agree with Mila that backup is imperative. It seems rather like an oxymoron in-as-much as the Drobo is redundant, but if the Drobo itself dies, then what? I've read of others using more than one Drobo for backup. The main reason for me to use a Drobo is that as good as backups are, (local or remote) if a single drive becomes flaky, you can lose data without knowing it and the backup then dutifully copies the bad data. By the time you realize there is a problem, you've already permanently lost valuable data. That was my experience. So hopefully my Drobo will warn me of drive issues before I start losing data.
