Do the sshd worth

Depends what you are using it for, whether you backup your data, how comfortable you are with using it etc.

sorry mdgm, what do you use a NAS for? AFIK are used as a backup storage.

Anyway I was thinking if the ssd part of the disk influences a lot the performances on a NAS system?

SSH doesn't use much in the way of resources in itself. It depends what you do with it.

I think he is talking about SSD - ie solid state drives.

Ah, Solid State Drives.

That makes most sense in e.g. a 716x if you need really fast performance.

For backup storage using SSDs doesn't make much sense as extremely high performance is generally not that important.

I'm thinking the query might related to solid state hybrid drives.

I doubt these will help much as LAN is the biggest bottleneck - with normal physical drives I can easily max out my gigabit port.

Ok... sorry, this is more related with my bad english.
I'm talkinga about Solid-state hybrid drive (http://en.wikipedia.org/wiki/Hybrid_drive).
Hard disk of new generation with a small part done with Solid State Drives with a fast access to the data and the rest with the old technology of the rapidly rotating disks (HDD).

Does it worths to use SSHD instead of HDD on a NAS system?

Hope now is more clear my request :)

I don't think they would be worth it. Gigabit ethernet is the bottleneck.

Also if disks are not on the compatibility list then if you use them you will be denied support.
