Hitachi HDS723020BLA642 2TB 64MB Cache

I just put this drive in an Ultra 6 today. Passed the self check and so far seems to be working without issues.

Thanks for the quick reply. Appreciate it !!!

Just a follow up. I now have 4 of these drives in an Ultra 6 plus system for a month now and I have had no issues.

I have 4 as well. No problems at all. I am putting another in this weekend.

Yes, would be nice if Netgear would test and validate this disk and the 5K3000 (5400 rpm) disks. The 7K2000 disks are going away soon so its gonna be necessary to provide a new set of Hitachi's (at least until WDC completes the acquisition and destruction of Hitachi's great disks).

I just bought 2 of these HDS723020BLA642 2TB 64MB Cache drives since they had the same number at fry's as my other two HDS722020ALA330 drives. Of course I just found out they're a newer version or not exactly the same in terms of numbers. In any case, I figured readynas has been slow and probably will never update their compatibility lists so I just went ahead with these instead of the 3 Terabyte drives since the first two have been working fine an now I see them on the list. I also thought I saw something about no support for the 3 terabyte drives on the NV+. Not sure about the 3 terabyte support, but I got one question? Do I need a jumper on the two pins to bring it down to 3GB/s? There's nothing in the box or sheet of paper that Hitachi includes. They normally tell you this, but I don't want to mess it up if they changed this. I read something about people doing this with software which makes no sense since they all have the pins, but I just want to make sure this is correct. Has anyone seen this information. I can't find it anywhere on the Hitachi site for these models. Also, they use a different number on the site than what's on the drive box so it's nice and confusing just finding the correct drive, at least for me anyway. Any help is appreciated. I haven't looked at this stuff since I set up my other drives and now I'm back trying to make it bigger since it's been nagging me that it's almost full for the last year or more. thanks.

Just a side note in case anyone is looking, fry's has the 3 terabyte drives for $109, but since I can't tell if they would work on this I'll just stick with the 2 since I already have two of them. This should keep me going until the others really come down even more.

Well, I decided to pop the drive in after reading a bit more on the sata specifications. I did a hot swap, but there was no change other than a message telling me the drive in bay x was pulled out. So after putting the new one in (HDS723020BLA642) I just powered off and rebooted, then I got "UNKNOWN 465 GB" since I'm still using the 500gb drives. So far the light on that drive is still blinking green, so I'll let it go and see if it does anything eventually because it's not telling me anything else. It does say the drive is DEAD. I sure hope it works, I don't want to have to go back and return these because I don't know what else to get since I couldn't find the same ones I had. I need the space anyway.

Jaime - if you are still having problems, please open a discussion in Upgrade (Under Boot, Installation, Upgrade and Expansion) for further assistance. This area is for experiences positive or negative, not extensive problem solving.

There are a couple of questions to be asked and answered to assist you.

I posted here because this is what you find when you search for this specific drive. So that's why I do it this way. I saw the other threads but didn't find anything that would help me. Thanks for pointing out the other thread though.

I understand. You were giving feedback. It's just that a solo discussion in the Ugrade or Expansion area is more appropriate for solving problems, for some of the discussions can get quite lengthy as we suggest something to try and then you give us the response. You did ask about the 6GB/s interface on the drive. These drives will automatically adjust to the fastest available speed of the MB SATA port. In the case of the entire Ultra and Pro series, that is 3GB/s.
