A particular application has a need for two different types of data to be stored. One part of the application generates small block, highly random I/O, while another part of the application generates large block, sequential I/O. Which of the following provides the BEST combination of performance and cost effectiveness?
A. SAS for small block/random I/O, SATA for the large block/sequential I/O
B. SATA for small block/random I/O, SAS for the large block/sequential I/O
C. SATA for both types of I/O
D. SAS for both types of I/O
