  Re: what is disk interleaving? why is disk interleaving adopted?
Answer
# 1
A group of disks may be interleaved to speed up data 
transfers in a manner analogous to the speedup achieved by 
main memory interleaving. Conventional disks may be used 
for interleaving by spreading data across disks and by 
treating multiple disks as if they were a single one. 
Furthermore, the rotation of the interleaved disks may be 
synchronized to simplify control and also to optimize 
performance. In addition, check- sums may be placed on 
separate check-sum disks in order to improve reliability. 
In this paper, we study synchronized disk interleaving as a 
high-performance mass storage system architecture. The 
advantages and limitations of the proposed disk 
interleaving scheme are analyzed using the M/G/1 queueing 
model and compared to the conventional disk access 
mechanism.
