Thanks to all for your replies.

I do have a ID41 card that is in my 808v5 so that is the end point.

My question was is there a possibility that M may go to SSD's for the MD600 to help with the problem of drive concerns?

Hector I really appreciate your filling me in on the issues that I may come across if I decide to move forward now after gaining more insight on this unit. I do have a location that the unit will be remote so the noise of the fan or drives won't be an issue. I am just concerned about the loss of storage and the money spent to have something that may be prone to disappoint.

I would want to stick with the MD600 but it seems like a roll of the dice. Hector if I may ask how many hours, or time in months or years did you have on your unit before it became unstable and was it only the drives and nothing else contained within the MD600 that was of concern?

I see you still gave the unit some thumbs up. Is there anyone else who has experience with this unit that would chime in and either recommend it or should I seriously consider going down another avenue.

I see that many others do have them listed in their equipment kit list in their postings.
