Sorry but that is the primary reason to not fully trust the client when it is your neck stuck out not theirs. My guess is they did not want to spend for the enterprise drives got some hack in to “build” the server then when the guy figured out they were going to lose money supporting it they backed out.

I took the word of the client, and since I didn't see any yellow exclamations in the iDRAC it didn't dawn on me that these are consumer drives but that is what they told me the server is using Samsung SSD 850 _____ From: [email protected] <[email protected]> on behalf of Richard Stovall <[email protected]> Sent: Tuesday, September 20, 2016 6:21 PM To: [email protected] Subject: Re: [NTSysADM] Re: raid 5? in 2016- If you don't have seriously high iops needs, I doubt you need raid 10.

As for your question, “aside from a losing some space wouldn't a raid 6 and hot spare make MUCH more sense?” Well, the answer is, “it depends” (probably, but I like throwing that out there). J This site has been around for YEARS, and provides a good overview of the differences (pros/cons/uses) for different RAID configurations: <http://www.acnc.com/raidedu/5> http://www.acnc.com/raidedu/5 <http://www.acnc.com/raidedu/6> http://www.acnc.com/raidedu/6 I used it about 7 or 8 years ago to help me decide whether to go with RAID 10 or 0+1 on an Oracle DB configuration. (and no, I don’t remember which option I chose, or why).
