Write timeouts with different disk packs

Write timeouts with different disk packs
I have a puzzling issue with my Drobo 5N.

With a disk pack consisting of 5 x 4TB HGST drives installed, my Drobo boots, mounts, and reads files just fine. However, when trying to write to the share my write function stops and eventually times out. The Drobo activity LED remains active for a few minutes after timeout. This happens with any transfer more than a few hundred MB or so.

After 5-10 retries of the same write the Drobo is fine - I can write/read with no issues at all until reboot.

Here's where it gets weird. With a disk pack consisting of 5 x 3TB Western Digital drives installed my Drobo functions perfectly. No problems at all with read or write. This behavior is consistently reproducible. Any time I switch to the HGST drives I get the same problem.

The WD disk pack was the original set with my 5N. Any insight into why I'm having trouble with writing to my larger disk pack? Anything I can do to fix the problem?
