Is Drobo DAS good for Premiere Pro editing?

[kwcalm]

The user does video editing with Adobe Premiere on an iMac with Thunderbolt 2.

They are looking for a well-priced 16TB RAID 5

Would the following configuration be good?

• Drobo 5Dt: 5-Drive Direct Attached Storage (DAS) Array with mSATA SSD acceleration - USB 3 and Thunderbolt 2 ports (Empty) DRDR5A21-T  (3.5 stars on Amazon)
• Seagate 4TB IronWolf NAS SATA 6Gb/s NCQ 64MB Cache 3.5-Inch Internal Hard Drive (ST4000VN008)  (5 of these)

The cost looks to be about $1100.00

Is there another manufacturer that we should look at?

Any problems with Drobo?

Thanks

I have two older Drobos and neither are fast enough for editing, great for backups though. I have no experience of the newer ones, I'm sure they're faster but might not be fast enough.
