Are WD SE drives worth it over RED drives?
-
like the title asks, are they?
I have a Drobo 8 bay - do I really need to go SEs since I have more than 5 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?

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).
