Small mSATA SSD drives slowly become more and more popular since, due to their tiny size, they are ideal for use in ultra-portable notebooks and on motherboards. Gigabyte has a long list of motherboards with mSATA slots which initially were meant only to be used as a caching solution with small SSDs installed; as NAND flash prices dwindle however, it quickly became possible for mSATA drives to replace even the main drives of either desktop PCs and or ultra-portable notebooks. Today we are having a look at such an mSATA device, the Crucial m4 256GB drive, which has the full potential to become the primary disk of either ultra-portable notebook or desktop systems with an available mSATA port.
