SD-card does not equal SATA-SSD or mSATA.
SD-card = Secure Digital http://en.wikipedia.org/wiki/Secure_Digital
SSD = Solid-State Drive http://en.wikipedia.org/wiki/Solid-state_drive
NAND = http://en.wikipedia.org/wiki/Flash_memory
SD (Secure Digital) card should not be used as storage for the operating-system, caching, logging, or any other operations that require a intense amount of read and writes.
You will want to use either embedded-NAND/SATA-SSD/mSATA, or a mechanical hard drive, or a combination of the two for the operating-system partitions, and any partitions used for caching or logging.
Best value is to keep a smaller embedded-NAND/SATA-SSD/mSATA for the operating-system partitions, and any partitions used for caching or logging that need fast read performance and is access often, and a cheaper mechanical hard drive for any large media mass storage, such as the users movies, music, and pictures.
This is why Hybrid harddrive sulutions are becoming more and more popular http://en.wikipedia.org/wiki/Hybrid_drive as they combine the best of both worlds in order to offer the best value for your money.
For Linux based embedded systems there are also several hybrid software solutions such as bcache, dm-cache, and Flashcache
