Ultra 4 Drive Replacement and Upgrade
Hi, I have a Ultra 4 which is currently populated with two of the dreaded Seagate ST2000DL003-9VT166 drives with firmware version CC32 (see here if you don't know what I'm talking about: http://www...
Of course, putting a backup plan in place is the most effective way to protect your data from loss.
I've been running the WD30EFRX in my Pro-6 and my RN102 and have been quite pleased with them. They've performed well, run cool, and are quiet.
There was a short time last fall when WDC mistuned the firmware, resulting in increasing load-cycle counts. So you should make sure the drive firmware is up to date before you install. You can also adjust the head parking settings with a tool from WDC. This issue never affected me, but there are some posts here about it.
If you can live without the data for a bit, I'd be inclined to do the "start from scratch".
One benefit of rebuilding is that if something goes wrong with the backup restore, you can fallback to powering down the NAS, and reinserting the original two drives (other two slots empty). The disadvantage is that your data will be unavailable for a couple of days.
If you started with 2 TB drives, then you can't expand beyond 10 TB volume size. That wouldn't be a problem right now (you'll end up at 9 TB), but it would be an issue if you upgraded to 4 TB drives later on. Rebuilding from scratch would let you expand up to 16 TB in the future.
