I use my Drobo v2 as an on-site archive for all my photographic work. A bit of background. I have a system that effectively works as follows:
Internal SSD - Live Edits (Stuff I am currently working on)
Internal HDD - Recent Edits (Stuff I may need to access heavily again soon)
Drobo - Image Archive (All shoots that are deemed ‘finished’)
I obviously also backup my work offsite.
During the ‘life’ of a shoot the files move from the Internal SSD to the Drobo, sometimes skipping the HDD if it’s wrapped up fairly quickly. I use Lightroom 4 to edit and manage my images. My LR Catalog lives on my SSD and I have a fairly large catalog of around 160k images. The Drobo also houses my LR catalog backups.
Because of the manner in which Lightroom works, to keep things in sync with the catalog it’s neccessary to perform file moves from within the LR interface (else LR loses track of stuff). Over the years this has never really been a problem and it’s worked well for me. As a shoot is completed I pick up it’s folder within LR and drag its next home (SSD, HDD or Drobo).
Drobo has never been ‘fast’ but it’s always been reasonable. Copying a large 30GB wedding will normally take less than an hour I’d guess. It tends to be something I leave to it’s own devices so it’s hard to be sure of time, but like I say, always been perfectly reasonable in terms of transfer speeds.
However, now, it is being RIDICULOUSLY slow when performing moves to the Drobo. 4 or 5 hours for the same size folder of images is not uncommon. So slow in fact that on numerous occasions I’ve had to wonder whether the copy has failed.
Further investigations shows me that copying files from within the finder (rather than within LR) is also painfully slow. I’ve just watched it take around 2 mins to copy 10mb from my computer to the Drobo. It’s estimating 4hrs for a 3.8GB copy.
As I discussed in the below post, I recently upgraded my Drobo but Drobo Dashboard suggests everything is fine and the upgrade seemed to go smoothly:
What could be causing this ridiculously slow transfer rates? It’s a concern to me as although my images are backed up to archival grade DVDs the Drobo allows me an accessible archive. I’ve tried running Disk Utility on the Drobo to no avail, and as Drobo Dashboard offers so little feedback I’m rather stumped.
Any input would be much appreciated.
