Replacing G-RAID drives with bigger capacity disks.
on Mar 5, 2015 at 1:42:58 pm

I'm looking to change the 2 3TB drives of a 6TB G-Raid model to 2 x 4TB drives.

Does anyone know if they prevent you from doing that by designing the raid controller to only work with that specific disk capacity/disk model?

Cheers!

What G-Raid are we talking about?

Normally the big manufacturers have a drive compatibility list (f.e. Sonnet or Promise).
I couldn't find one with G-Tech.
The two bay Raid is sold with 4TB and 8TB.
I would look what Discs they use and would put the same (f.e. Hitachi Ultrastar) two 4TB Discs instead of the existing 2TB models in it. To me it will work.
What are the numbers of the existing disks ? (f.e. HUA723030ALA640)
cheers

Thanks for your reply.

I'm talking about the g-raid drives without removable disks. The ones with 2 drives striped together.

I don't think there's a drive compatibility list as they are not officially user replaceable (at least I think).

I just opened one up, this drive is inside:

Hitachi Ultrastar DK7SAD300

http://www.hgst.com/tech/techlib.nsf/techdocs/EF593BD721D5D2768825782D000B8...

Can't seem to find any references to TLER or something, seems like normal consumer drives.

Thanks for the feedback!

The Ultrastar is a enterprise class disk.
You have got the wrong number, Ultrastars are always HUA....

You are correct, the manual for DK7SAD300 referenced both deskstar and ultrastar.

Thanks,
K.

Look again on the Disk
and search for a number beginning with HUA... or HDS....
HUA is Ultrastar HDS IS Deskstar

Hi,

Yes, it says DK7SAD300.

Meaning they are using consumer drives in their raid products…

You are right,

ist a Hitachi Deskstar its a HDS723030ALA640. I would put another 2x Deskstar 4TB HDS724040ALE640 in the enclosure. It should work.

cheers

But be careful and back up everything. This Raid works with Raid0, so if one drive fails all data is lost - no chance of recovery,

cheers

Hi, things worked out. I replaced the drives from 2 G-RAID 6TB drives.

I used Hitachi 4TB NAS drives H3IKNAS40003272SE. Perhaps the non NAS version of that drive works as well, don't know.

I'm re-using the old 3TB drives in my server.

Cheers!
K.
