4TB drives coming out....

There are no 4TB disks on the compatibility list at this time.

However I can see no reason why 4TB drives in general wouldn't work. Some models of 4TB drives may have compatibility issues so best to wait for drives to be added to the compatibility list.

Hi,

It would really be nice to know what the score is with the 4TB drives. Tested, failed, pass and not tested, or is there other issues with them. A bit of feedback to us (the user) wouldn't go a miss.

Regards Ian.

Bump, 4TB drive compatability (NVX Pioneer specifically). Thanks.

Edit: Also 4TB drives can be swapped in one at a time increasing storage each time over a 4x2TB set up correct?

Bump.

Several people are using them, search the forum for specifics.

Shifting off the HCL can/will create issues getting support later - just something to keep in mind.

You can hot-swap them, though the usual expansion limits apply (no more than 8 TiB growth over the live of the volume, cannot expand over 16 TiB).

Sorry no idea what you mean here.

So if I began with 2 1TB drives I would max out with 10 TB using 16TB of drives?

Thanks!

HCL - "hardware compatibility list" http://kb.netgear.com/app/answers/detail/a_id/20641
Note the warning: Be sure to use only drives recommended in the compatibility list, otherwise, NETGEAR Technical Support can and will deny support.

Thanks![/quote]You seem to be mixing up the two constraints.
If you begin with 2x1TB, you start with a volume size of 1 TB. You can expand that to about 9 TB.

The 16 TiB ceiling is separate. If you start with 5x4TB, you'd have a 16 TB volume size with RAID-5/xraid single redundancy. You can't expand it any more.

These limits apply to 4.2.x systems and 5.3.x systems - they don't apply to the new OS6 products.

I did look there. No 4 TB drives listed in the HCL for the Pioneer NVX only 3 TB

Got it that is more clear. I have a 4.2.x system. How can I check if I began with 2x1TB? I may have started fresh with 4x1TB since that point in time. Thanks again.

Understood. One downside of using them is that you could lose support.

Download the log files. initrd.log will tell you the time of the initial install/factory reset.

If you search expansion.log for "Extending logical volume c" you will see the various sizes (including the initial install).

Thanks, only spotted one expansion, and can't seem to locate an initial size, which is the critical one...
