我想请问一下各位大神第11题
为什么答案不用再乘上10个track per cylinders 呢
: 10.An IDE hard disk spins at 7200 RPM, 1000 cylinders,10 tracks per cylinder
,
: 100 sectors per
: track, and 512 bytes per sector. The disk is formatted by a file system
: which the logical block
: size is 1024 bytes.
: 11.The raw disk speed of the above hard drive is about:
: (a) 120 MBytes/sec
: (b) 60 MBytes/sec
: (c) 12 MBytes/sec
: (d) 6 MByte/sec.
: (e) 600 KBytes/sec
: 请问这题怎么算呢？
: 7200RPM＝> 1秒120圈
: 1圈100 sector
: 1个 sector 512byte
: 120*100*512=6 MByte/sec
