        @obsolesce Nice to confirm what most of us have been saying already.

          Yeah its nice to see the numbers.

            There is also the reliability rate to consider. SSD drives have 3 to 4 times lower annualized failure rate.
            And you're more likely to use more 15K drives and do RAID 10 instead of RAID 1 with SSD.

            Regarding SAS/SATA SSD they will all disappear soon. NVME drives in the U.2 format have superior performance and a small price premium per GB compared to the same drive in SATA.

            As far as I'm concerned SATA/SAS SSD should be bought for legacy use only.

              That is totally not useful as the server manufacturers are not manufacturing servers to use those generally. Once that changes then I would recommend switching to those.

                That might have been true in the past. But just looking at Dell Poweredge servers with one or two sockets, the following support hot-swap NVME drives : R6415, R7415, C4140, R440, R740xd, R640, R7425.

                  Good eye Pete. I would consider moving to NVME at some point! It's going to be a game changer.

                    Yes, it is becoming standard, but it is not ubiquitous yet.
