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
