      I set up my servers with RAID 10 and 10 or 15 K RPM Drives and a dedicated RAID card and an SSD Drive for CacheCade.

      However with the decrease in pricing for SSD drives, I would like to start using them more in servers.

      1. Still do RAID 10 with SSD's?
      2. Is a dedicated RAID card still needed if using SSD's?
      1. Usually RAID 5 makes sense. Still RAID 10 if you want maximum performance. Be aware that you can saturate almost any SATA/SAS controller with the performances of 6-7 SSD.
      2. Apply the same consideration for the HDD.

      I actually came here to ask about #1 - is that 6 drives in raid10? Has anyone measured this / tested it etc?

      Yes, xByte tested that. It saturated REALLY low.

      That's interesting. I didn't know that.

          That's not a way to measure RAID reliability. I actually a video about why we never mention "number of lost drives" in the SAMIT queue.

          Which one? You have several RAID videos.

          It posted.
