The drive I found on ebay has a picture of the actual drive. When I found the difference, the link I posted, then I could see the drive is a SAS. The link I found explained that a SAS drive will not work with a SATA port like I have. It can work the other way around tho like you have. So, if I had a SAS controller, I could use SATA drives or SAS and it work. However, I have SATA controllers and can not hook up that SAS drive. They make a adapter and I found those on sale but I'm not willing to spend $150 to see if it works. It might, it might not. Either way, I get the difference between SATA and SAS now. Different connector but seems to be a much more durable drive. I thought I read a year or so ago the connectors was different but I wasn't sure. I thought maybe I misunderstood something or was just wrong. Turns out, it is different. The one thing I wasn't sure at all on, PMR or SMR. It appeared to be PMR but I couldn't confirm it with certainty. It seems drive makers are being pretty deceptive on what drives use. I did find a WD Red 8TB drive. It costs a good bit more. It's a good deal but still costs more. I'm going to keep looking. Eventually I'll either spend the money on the drive or find a really good deal. My home directory is at 69% so I got some time left. Of course, my collection is still growing. o_O Thanks for the extra info. Dale :-) :-)
