SAS drive support
After a server upgrade at work I have Seagate Constellation ES drives spare - model ST32000444SS
They are essentially 2TB 6gb 7.2k drives.
It looks like they are not supported drives in a ready nas but that they may work? can anyone confirm.
It's not for use in a production environment, just to use as a dumping ground for old data.
Going inside a readynas pro business edition 6 bay running latest software build.
I could just try but there are three drives in there now with data on and I don't want to lose that data on a hunch.
Thanks.

- Fist attach the new drives to a PC and delete all the partitions. (If on Windows, Drive Management will do this nicely).
Then - simply do a normal shut down of the Pro BE and remove the drives noting the bay in which each is supposed to go (I put a small stick label on each drive, some mark the drive). As long as these drives are removed when the NAS is shut down, they can be returned to the unit when shut down and rebooted without any problems.
If you are only going to use three of the new drives, then you can use the spare trays. If not, you can remove the normal drives from the trays, mount the ST32000444SS in the trays, install in the Pro BE and boot the unit. I would probably try only one drive at first, as if it accepts the drive, there won't be a long wait for a resync. If there are problem, or if you need to access the data on the normal drives, simply shut down, restore the original drives to their original bays (without any of the new drives in the unit) and reboot. It should come up normally.
Of course a full backup is nice. If the new drives don't work, you can always attach them to a PC and use them for a backup target using copy/paste. Then you can store the drive offline in a cabinet. I did that for years with older drives until I got my second NAS. Or you could simply see if they will sell on ebay. - the ST32000444SS is a nearline sas drive and will not work in any readynas since sas is not supported (you wont even be able to plug the drives in due to incompatible connectors).
you can only use the sata variant of the constellation series. - Well, now that I look up an image of one on Newegg, that is very true, the connector is totally incompatible. They will also not attach to any PC using SATA connectors. I now know what the SS at the end means and I did not catch that earlier.
Magic8Ball - by now you have probably discovered the connector problem. - ReadyNAS does not support SAS driver,
Netgear has released ReadyDATA 5200 which support SAS driver,
http://netgear.com/business/products/st ... fault.aspx - SATA II or III (3 or 6Gb/s) disks can typically connect to a SAS controller. However, not the other way around. SAS requires a SAS controller.
