So it's time to upgarde my parity drive with a 2TB drive but all the new hard drives for sale do not have jumpers in the back for setting the transfer speed from 3 gb/s to 1.5 gb/s and my motherboard and add on Sata cards are all 1.5 gb/s. I called Western Digital and they said the speeds are now set with software, but this server uses unraid, of course. I also read if you don't have the speed set correctly on older drives with the jumper option that it won't work right.

 

Any suggestions, thanks.

Try it.  Worst case, it will not work at all.  Best case is it will negotiate the 1.5gb/s speed your motherboard and add-on cards are capable of.

I don't think it's going to matter. I just put a brand new Seagate ST32000542AS (2TB LP 3GB/sec SATA) in to a 4 year old Buffalo LinkStation (running Linux) and it just works.

Pretty sure it auto negotiates. Why would they go backwards in technology? IDE auto determined the correct speed, makes sense that sata would too. Did you at least try the drive before contacting WD and posting here?

By the way, I'm using three new drives just fine on a sata 1.5 card. No problems.

The on-board 2-port controller on my old Intel board and the PCI based controller card I have are also just SATA 1.5.  Both have worked with a variety of 7200 RPM drives I've connected.  (And with a PCI based system, it really does not matter if you use SATA 1.5 since the PCI bus can't go faster regardless once you get past a few drives.)

Yes it worked, thanks for the help. The reason I didn't want to try it first was I called WD and they told me that it's software based in windows and all posts I read in other forums said I might get corruption and since it's my parity and took 2 days to redo I wanted to be sure. So it's working good. thanks.
