IOPS for optical-media

[Preeti Gupta]

Hello,

I am looking for data on IOPS and bandwidth provided by optical-media. I am doing it to do the cost-benefit analysis of using hard disks, SSD, optical-media, and tape. I see that while bandwidth for tape, hard disks, and SSD is defined in terms of MB/s, for optical-media, it is defined in Mb/s. I found that for optical-media bandwidth is approximately 60 Mb/s which would be close to 8MB/s. This seems quite low. However, when I use CD or DVD in my laptop they don't run that slow.

I could not find any data on Input output operations provided by optical-media. Do you guys have any numbers on that?

IOPS = (MBps Throughput / KB per IO) * 1024

MBps = (IOPS * KB per IO) /1024

where MB = megabyte KB is kilobyte
