Are WD SE drives worth it over RED drives?
-
What will you be doing with them? Is this for long-term storage, production load, backup target, etc.?
-
primarily as a backup target

-
SE drives are URE 10^15 while Red are 10^14.
SE drives are 7200 RPM and Red are 5400 RPM.
Drobo is always parity, there is no mirroring option. So unless you are dealing with a cluster of them, I would rule out Red drives.

Reds should be fine.
Based on that it is backup and dataloss is not a major concern?
Depends, how important is the backup data to the organization?

until I get an offsite replicated setup in place, I'd say it's fairly important.

Then Reds are not even an option.

What redundancy level on the Drobo do you plan to use?
-
Which Drobo do you have?
-
The drobo has been in place for 3+ years already. I'm using single drive failsafe... looks like I need to move to new drives and dual drive failsafe.
It's an DroboPro 8 slot. It currently has five 1 TB drives, but it's running low on space. What I'm currently unsure of (haven't read up on it yet) is how I expand the space when I do actually install more space than I originally allocated.

3 years is getting kind of old for a device of that nature. You may want to just replace the whole thing.
-
Really? Do you recommend replacing a unitrends appliance every three years?

The Unitrends boxes are generally a little bit more robust than a Drobo, though I really don't work with Unitrends at all. If it's as important as you say it is, why would you want to take that chance?
*Edited for disclaimer.

I'm trying to get management to retire our old EMR so I can repurpose our old server as a SAMSD for backups... this is my end goal.. unfortunately they don't like their new method for old data access and are requiring that I keep the old system online for now.

Not really comparable devices. Unitrends is a different class that's SuperMicro that it is built on.
-
The DroboPro was the forerunner of the B800fs which is already long in the tooth.
Id stick to double redundancy in that.
-
Three years isn't horrible. It's not like they expire.

For this purpose, this is kinda of what I was thinking... Perhaps replacing the drives as they get close to warranty time, but nothing more than that should be needed (though that replacement does cause a lot of drive activity).
-
I would have a cold spare ready but not replace proactively unless, you know. Like ten years old.
