What are the top three mistakes people make when switching data from HDD to SSD storage?
First, the biggest mistake I see people make is not understanding the unique behavior of solid-state storage and treating solid-state drives (SSDs) the same way as hard disk drives (HDDs), and overprovisioning them the same way, too.
Another mistake is looking at price rather than value when purchasing solid-state storage. The common metric in purchasing HDDs is usually price per gigabyte. This metric does not demonstrate the value they will be getting from using solid-state storage. The metric needs to change to price per performance. When a price-per-performance metric is considered, it is possible to calculate the true total cost of ownership of a solid-state storage purchase.
Third, people expect the "out-of-the-box" performance they see on the first day will be the same level of performance they will see months later. When SSDs are first used, they yield a temporary artificial performance hike, but then settle down to a steady performance level once the cells have been written to.
