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...
