Hi Folks,

Need some advice.

I have just aquired a pair of 2nd hand, 4 bay Drobo units without drives. (DRO4D-D)

I'm intending to use them with my new Imac 27" 2017 (1Tb ssd) to store and keep image files in my photography studio.

The plan being to keep just apps and working files on the imac, then transfer to the Drobo once completed. The second drobo unit can mirror the first (using Carbon copy cloner or similar) and be kept off site , ie: at home.

Only issue is that some files regularly need to be retrieved from the Drobo and transferred back to the imac when updating team photos etc. These files can be up to 20 layers and are often around 2gb in size.

So do I invest in 7200 or 5400 speed drives?
I'm looking at 3tb or 4tb capacity drives.

Thoughts?

Cheers
Andy
