RAID 10 for 809u, limitation of system board?

[patriots]

Is the reason, the 809u-RP does not support RAID 10 due to a system board limitation or is it because it is not enabled in the firmware?

Thanks,

It is not enabled in the firmware.
We recommend you use RAID5/6 instead of RAID 10 due to the capacity and stability issue.

Strange - would raid 10 not increase performance over RAID 6? Thecus also offers RAID 10, so are you saying this should cause stability issues with their products too?

Hi rrnworks,

We believe that the performance of RAID6 is almost the same as RAID 10.
Besides, RAID 6 has higher capability in that it allows for any two damaged disks, RAID10 may fail if two specific HDDs also fail.

Thank you for your advice, we will consider adding this feature in the future.

Hi,

Thank you for the quick reply.

I believe having Raid 10 will be a great addition.
Capacity really isn't an issue any more considering that with an 809
series unit, you could populate it 8 x 2TB drives. Setting it up in
a Raid 10 will still give you around 8 TB or so storage capacity.

Plus Most if not all DataBase appliacations recommend Raid 10 for best overall read/write performance.

Hi patriots,

In my first post of this thread, I should say "capability" not "capacity".
What i meant is in RAID6, you don't need to worry about data loss if any two disks are damaged.
But in RAID 10, you will be in a risk of losing data if two specific disks are damaged at the same time.

Leave it up to the client to decide what if more appropriate for them based on their application workloads. Don't try and make the decision for them.

You're not going to be considered a serious contender in the SOHO market without offering RAID 10.

Hello Bunce,

We did not plan to make the decision for them.
What I did is trying to explain what's QNAP's consideration on RAID10.

Thank you for letting us know your requirement.
We value every opinion from our customers and will look into RAID 10 in the future roadmap.

Thanks Qnap. I will say, I would rather see RAID 6 support in a NAS before RAID 10 - so I will plan on using your RAID 6. And if performance is really the same, then RAID 6 makes more practical sense on all levels. But from a marketing standpoint, RAID 10 could make you more competitive.

Ignorant alert?

SOHO users deffo won't use RAID10 due to lost of space vs. RAID5/6. If performance is the same why would you give up half of the storage space?
