Briefly described, the RAIDBank4 is a 4.85 x 6.5 x 9.1 inch box which holds four SATA hard drives (in this case, there were four decent quality Western Digital 500 GB drives). Micronet bills this unit as the "world’s smallest RAID". While I don’t know this to be true, I don’t think it could get much smaller.
