I have a LaCie 2big Network that currently has 2 500GB drives in it (mirror).

I'd like to upgrade the drives to 1TB each using something like this

I know that Lacie sells a 1TB drive designed for the 2big Network but it would seem to me that these drives are standard drives with the Lacie holder included.

Do I need to use their drives or can I get my own? (Their customer support pushes me towards their drives) I'm assuming the device can format the drives for me when I add them in.

They are hot swappable; you can replace them with any drives which meet the specs defined by the hardware. They do not need to be LaCie drives; however I would get the same make/model with varying manufacturer dates for each drive existing in the array.

SO, I can get 2 1TB drives and take one 500GB out, throw in the new 1TB and let it rebuild then repeat the process for the other disk? – Jason Mar 4 '11 at 15:10
@Jason Yes...that in theory would work. RAID can be an interesting animal...proceed with caution (make certain your data is backed up before proceeding). – Aaron McIver Mar 4 '11 at 15:55
@Jason Keep in mind the drive will need to be formatted via LaCie software if they supply it or via other means before it can be used. – Aaron McIver Mar 4 '11 at 16:01 looks like Lacie keeps the system on the disk so I'll have to try to rebuild it...keeping my fingers crossed – Jason Mar 4 '11 at 18:42
@trisweb It was, I went from 500GB drives to 1TB drives. I did one at a time...Swapped out one, waited a week, then did the other. I purchased 2 1 TB Hitachi Deskstar drives (7200 RPM). I can't remember it being terribly difficult of a process either. – Jason Sep 15 '14 at 18:43

I did the same yesterday, after breaking my head about the fact that replacing both disks at the same time does not work. There seems to bee some kind of linux software on the drives that make them "network". replacing both drives at the same time means the device is NOT accessible anymore. The trick that did it: replace one drive by the bigger one, go to the admin page to the RAID section and add this new drive. the drive is being added but no change in total disk size. after the raid is rebuild (takes some time), exchange the second drive and do the same procedure. After both drives are rebuild, format the raid and the total disk size is correct

I'm about half way through this exact far, so good. Thanks – Jason Mar 5 '11 at 11:50

Just make sure to backup your data elsewhere!! All data is lost when you rebuild the raid..

You DON'T need to use Lacie spare drives - You just have to swap ONE disk at a time, just like "SalF" wrote. Replacing BOTH drives at the same time will leave you with a NAS without an OS..

If you use ghost and do a sector by sector copy you dont need to do the mirror process and you can do data as well but it took me 5 hours for 1.5 tb x 2 drives I replaced mine with 2x3tb drives
