      Yeah. And not only did he lose everything on RAID 5, but it was on an MSA
      Didn't read the thread, but saw that on the link..

      (the MSA didn't fail, but seriously people, who is buying this stuff) and then practically everyone in the thread including the OP and the main person responding, literally don't know what RAID 5, have no idea that it is bad or know how it works. At least the OP and the main person are unclear and can't be convinced that two lost drives on RAID 5 means that the data is lost!

      RAID 5 is single drive parity and even Wikipedia clearly says that if you loose more than one drive, you're screwed. If someone doesn't understand that by 2016, he/she should probably better look for some new profession.

      Well, he come on now, we still fully recommend RAID5 SSD arrays.

      SSD is a whole different story

        It's a different condition for the same RAID configuration. So to say "never RAID5" needs to be adjusted to "Never RAID5 with classic drives and you must be prepared to replace any failed drives immediately"

          Sure. RAID can never replace a backup, that's something else people need to understand.

            That isn't the difference between SSD and Winchester drives in OBR5.

                  This is a lab environment already running hyper-v with 10-12 VM's per host, and he's now trying to determine what RAID configuration to use.

                  Um how?

                      I saw that as well, but whatever floats his boat (if it's a lab fine use RAID0 if you want)

                      Just hope he realizes what he's doing wrong.

                        Not sure where else to post this. . .

                        What does that even mean, "have you tried increasing the number of IOPS" . . . .

                                Continued to use a SAN way out of warranty / support options, and has dual controllers failing. Along with didn't make a backup of the VM he needed.

                                Damn.. that sucks, best practiced he's eschewed, not replacing critical equipment regularly and not checking his backups!

                                  And using an appliance without being in support. Black box approach has a vendor dependency.
