How to Calculate Storage IOPS and Capacity Like an Expert

How do you accurately calculate storage capacity and performance? When you buy ten 1TB drives, you don't actually get 10TB of usable space. And why does writing data to a RAID 5 array suddenly cripple your performance?

In this animated masterclass, we break down the complex mathematics of Enterprise Storage Sizing, IOPS, and the Data Performance Pipeline.

What you will learn in this video:
• RAW vs. Usable Capacity: Understand exactly how much space you lose to mirroring (RAID 10) and mathematical parity (RAID 5 & RAID 6).
• Calculating Base IOPS: How to measure the raw speed of your physical disks.
• The RAID 5 Write Penalty: A visual breakdown of why a single host write explodes into four distinct backend operations (Read, Read, Write, Write).
• The Performance Pipeline: Why true performance depends on Cache Hits (fast RAM) vs. Cache Misses (slow spinning disks), and how network bottlenecks choke your data flow.

Whether you are a Junior SysAdmin, a Storage Engineer, or studying for your IT certifications, this visual guide makes complex storage math easy to understand!
