Again I bet it depends on the application but our experience with the older Intel 710 series is that their performance out-runs the CPU, at least under our PG workload.How many people are using a single enterprise grade SSD for production without RAID? I've had a few consumer grade SSDs brick themselves - but are the enterprise grade SSDs, like the new Intel S3700 which you can get in sizes up to 800GB, reliable enough to run as a single drive without RAID1? The performance of one is definitely good enough for most medium sized workloads without the complexity of a BBU RAID and multiple spinning disks... -Dave :-) - |
