Cost Per GB Formula:
| From: | To: |
Cost per gigabyte is a metric used to evaluate the price efficiency of storage solutions. It represents how much you pay for each gigabyte of storage capacity, allowing for easy comparison between different storage options.
The calculator uses a simple formula:
Where:
Explanation: This calculation provides a standardized way to compare storage costs regardless of the total capacity or price of different devices.
Details: Calculating cost per GB is essential for making informed purchasing decisions, budgeting for storage needs, and comparing value across different storage technologies and vendors.
Tips: Enter the total cost in dollars and the storage capacity in gigabytes. Both values must be positive numbers, with storage capacity greater than zero.
Q1: Why calculate cost per GB instead of just comparing total prices?
A: Cost per GB normalizes the comparison between storage devices of different capacities, giving you a true apples-to-apples comparison of value.
Q2: Does this calculation account for performance differences?
A: No, cost per GB is purely a capacity-based metric. For a complete evaluation, you should also consider performance, reliability, and other factors.
Q3: Should I include additional costs like cables or installation?
A: For accurate comparisons, include all necessary costs to make the storage functional. This might include adapters, enclosures, or installation fees if applicable.
Q4: How has cost per GB changed over time?
A: Storage costs have consistently decreased over time, with cost per GB dropping dramatically as technology advances and production scales.
Q5: Are there different cost per GB calculations for different storage types?
A: Yes, different storage technologies (HDD, SSD, NVMe, cloud storage) typically have different cost per GB profiles, with faster technologies generally costing more per GB.
