Any performance and encryption needs and specifications need to be understood. Cost-effective SSDs are an affordable upgrade to existing storage installations and provide flexibility to support read and writes of different block sizes. Reliability is both the expected lifespan, and a way to ensure that data was written properly and will be secure. The SSD product has additional standard-compliant features that should be considered. Some examples include HIPPA for medical applications, as well as FIPS 140–2, TCG Enterprise and Opal 2.0.
